Oshlun Professional Grade Saw Blades

I've just installed it on my DeWalt DWS 782, so I can't speak to longevity. However, it works and the laser line is right on the money. Bonus points for including extra batteries. Also, the hardest part of installing it was the process I would normally have to follow for changing the blade on my saw. Lastly, make sure you tighten the bolt on the blade properly. I thought I tightened it enough without ham handing it, but once the blade brake turned on the blade broke most and kept spinning.

Great blade for the price. I've been using this daily for over a year, and it still cuts clean and crisp. I make sure to remove any build-up of material behind the teeth, so it doesn't burn the wood, but other than that it's been no trouble at all. Definitely a decent alternative to the Festool blades.

This is my new favorite demo blade.

I spent a day with this blade. It cuts rough, but for demolition work that doesn't matter. It managed to cut through a few hundred deck screws, and rip up a few sheets of plywood that had been coated in 1/4" thick epoxy and fiberglass. This blade is a beast - after all that it's still perfectly sharp and hasn't taken any damage. Besides being so durable, it's really QUICK cutting.

Prior to using this, I had been doing demo work with a sawzall with demo blades. This thing lasts way longer and cuts much quicker. After putting this in an old circular saw, I barely touched the sawzall.

I bought this to cut up left over Ipe decking. That stuff is harder than the hub of hell. I am very sure on softwood even 20 years Doug fir it would cut like butter. The Ipe is too dense and the blade need more teeth to cut quickly.

Good fit. Initial cuts worked well. I made 80+ cuts through that were 1-7/8" deep in 1" thick alum flatbar.
About 2/3s of the way through the blade started to struggle, but we were able to complete the project. Would probably recommend a cutting lubricant next time.

Product was shipped and delivered promptly after order was placed.

The blade set I received was in the aluminum case with heavy foam support around perimeter and foam sheets in between all blades. I am a weekend hobby woodworker and never used dado blades before the purchase. These work great for me! All the blades and shims in my set came clearly marked and I found it easy to make slight adjustments and dial in the exact width of cut I needed. I have a 15+ yr old JET JWTS series contractor saw and the blades and shims went on and off my factory 5/8" arbor with no problems. I will say that the shims can be a little tricky as they tend to find their way down into the arbor threads so be careful with that. All the blade teeth were complete and sharp (no nicks or quality issues as some other reviewers have cited). I have used once so far making many dado slots in MDF. The cuts were clean with a smooth, flat bottom. As the manufacturer clearly explains in the included literature the outer blade teeth are angled and slightly deeper intentionally to cut a crisp clean edge and bottom with minimal tearout. The minimal bottom corner groove produced by the outer blade teeth is barely noticeable and not a concern for me. Another positive for me was the full chipper blade design. I was down to this set or the similarly priced set from Freud. I had read a few reviews that indicated the partial chipper blades in the Fred set were not so easy to align and hold in place when installing on the arbor. That was a key factor in my choice of the Oshlun set. I have to say that even with the full chipper blades, aligning multiple blades for wider cuts can be tedious, especially if you need to use a few shims. I am very glad I went with the Oshlun in that regard because I understand now how much more difficult it would likely be with partial blades.

Overall I am 100% happy with my purchase and I highly recommend to anyone considering.

I never post reviews. Haven't even had this blade 24 hours, but this thing is awesome. I used this on a Dewalt 20v circular saw, the regular one, not the metal cutting saw. I wasn't sure if my little battery powered saw would cut what I was wanting to cut, and I saw no reviews using this blade on a regular 20v circular saw. I cut a 4'x8' sheet of 1/4" steel lengthwise. I didn't try to go super fast, but I was putting pretty good pressure. I was cutting at about 1" per 15 seconds, so it took a while to go the full 8'. I cut 2 feet at a time with 5 minute breaks in between. used 2 full 5ah batteries, plus needed a third battery to do the last 3 inches. I tacked a piece of angle to my plate to ensure a straight cut. The cut quality is perfect, way better than what my plasma would have done, or even a shear for that matter. Took a little while, took some planning on how and what to use to hold it in place during the cut, but I couldn't tell any difference in cut speed near the end at all. Still looks sharp and ready to cut more plates of steel. As long as you use your head, this blade will do wonders. I would bet you could even cut 1/2" plate with no problems, just using lots of batteries. I highly recommend this blade.

Bought the 30 tooth for thicker ferrous metals and 50 tooth for thinner ferrous and both cut great for there specific intention. Bought 5 3/8" size and used on my M18 Milwaukee metal saw. No complaints other then wish they made it in a
5 1/2" or 5 7/8" so that I can fully cut through a bundle of light gauge 1 5/8" studs in one shot as the blade wears down. They do sell the 5 7/8" for thicker ferrous metal but not ideal for light gauge studs because leaves thicker burrs and not as clean cut.

Bought this blade to cut 1/8" thick rectangular tubing for a project I'm making. I got about 50+ cuts on it now and seems to wearing out just a tad now. I could not tell the difference between this blade and the Milwaukee metal blade and this blade is a lot cheaper.

I love Festool, I buy their sanding pads for my rotex 150, I think you can't beat their quality products. I have to admit, forking out $125 for a replacement blade from Festool seemed steep. Went for this blade instead and let me tell you, this blade cuts just as good as the festool one, can't tell the difference, go for it. P.S: I cut wood only, not sure, if that's the case for other materials. Really glad I found this on Amazon.

Makes a clean cut on Glu Laminated Beams. Even cuts well at long angles. Got almost 100 cuts out of the blade on 5 1/8 deep glue laminated beams before signs of dulling showed. Would recommend this to anyone cutting large glue laminated beams or timbers.

Yep! This expensive blade cuts through stainless exhaust tube like BUTTER!!! Replaced the garbage cutting blade on my cheapo Harbor Freight chop saw with this bad boy and went from 45 second cuts to 5 second cuts with almost no pressure to cut through!

Nothing like making a cheezy tool work way better than it was ever intended! WIN!!!

We bought this for removing a breezeway between two buildings. We had to cut walls and the shingled roof, and then removed pieces with an excavator. This made the job pretty easy.
This blade is really heavy, and takes a bit ti spin it in the saw, but once it gets going, will cut through anything without issue. Cutting with it is pretty easy, if you can handle the hefty weight, otherwise it's easy to control.
Only downside was that it was definitely getting dull towards the end of the job. We had it sharpened, but haven't used it since, so we'll see if it's still usable or not.

I was doubtful that a blade costing less than half its competitors could be good. The consistently positive reviews convinced me to try it. This blade is a treat. I used it with a high school robotics team to cut aluminum plate and square section tube with 0.125in wall thickness. We made more than 100 cuts. I kept the blade lubricated (started with a liquid lubricant - messy- and switched to wax) and didn't force it, just let the blade do the work. The cuts were easy, clean, and smooth. I did use good practice to clamp each piece to the miter saw before cutting, not using hands to hold the workpiece. We didn't lose a single tooth and plan to use the same blade in the coming year.

I admit...I haven't used this yet. I bought it based on reviews from several woodworking friends and decided on this set rather than cheaper dado versions. I've been a woodworker for decades and used the old wobble dado version by Craftsman and wanted something that was easier to fine tune the width. This has it! The blades are plenty substantial, very heavy, with a variety of thinner spacers to fine tune the dado width. I'm looking forward to using this and can tell it's going to be perfect for my dado needs.

Cuts through metal like butter! I installed this blade on my Evolution Rage2 saw and it works flawlessly. Having recently upgraded to the Rage2 from an abrasive saw (NEVER again) the difference is amazing. No abrasive/metal dust everywhere, you get small metal shavings, but they are much easier to clean up and next to no sparks. The cut is smooth, clean, and accurate. No dross to clean up like with the abrasive saw.

Be mindful though that you rate of cut and amount of downward pressure must be carefully monitored. You should apply steady, LIGHT pressure, and let the blade do it's work. If you push too hard/fast you'll kill the blade. I expect this blade to last quite a while before needing to be resharpened ($20 at local shop). HIGHLY recommended!!!

Saws right through steel tubing. I was cutting up an old 1 3/4" farm gate for scrap and the blade got stuck. I could not get it out of the cut as it was pinched in the cut and I could not restart my saw. It was stuck tight. I jerked the saw out of the cut and one of the teeth on the blade popped off. This is a very good blade and I just pass this experience on to other users. If the blade gets pinched and you can't wiggle it out, be careful.

I used this in my 20v dewalt circular saw for cutting 26ga corrugated galvanized metal roofing (for raised garden beds). I ripped 2 panels at a time, lengthwise down the middle. Then i cut them across the corrugation and it did a beautiful job, and pretty quickly. I had to mount this blade on my saw with the label side in, so make sure you wear some goggles and gloves as the backward-pointing teeth will send sparks flying toward you.

I have been using these blades for several years as an economical alternative to Festool branded blades and I believe they may in fact be the same blade! Performance wise there is no difference at all. Would 100% recommend them to all serious woodworkers and DIY as well.

In addition to cutting sheet plastics, this blade cuts styrofoam sheets, leaving smooth edges and minimal "saw dust". I cut 1-inch and 2-inch thick sheets of styrofoam with excellent results. If you want to cut styrofoam with straight line rips, miters, etc. and have a table saw, this blade is the ticket.

Since there aren't many reviews on this blade I figured I'd give it a rating. I bought this to attach to a husqvarna 165rx clearing saw. Having previously used another carbide tipped blade (husqvarna Christmas tree attachment) and after wearing that blade out I was in search of another as rebuilding the blade alone would cost 1.5x the cost of this blade. Sharpen style blades just don't cut it so I figured I'd give this blade a try for what it costs.

I am throughly happy with this blade purchase as it mets my expectations with flying colors. I am mostly using this blade for pasture brush control (hedge, cedar, and locust). Cuts trees like a hot knife easily cutting down a 6" tree, can cut bigger with a back cut but trees get fairly tall with that diameter and could potentially fall towards you without a way to stop it due to having to hold saw. I have not hit any rocks or wire with it yet so I can't tell you how it would hold up to that but I feel like it would. If I happen to hit a rock or wire I'll report back with details if teeth fall off. Eventually I know the blade will get dull, hopefully I will cut enough trees coupled with not having to sharpen it to justify the cost and order another.

There is one thing that I am disappointed with is the blade is manufactured in China. I didn't rate it negatively for this because I feel that if it was a USA made blade it would probably be in the $80 -$100 range.

I would highly recommend this blade for a similar situation as mine. If by rare chance you have a clearing saw with a Christmas tree attachment (used for husqvarna clearing saws and allows use of 12" blade, normally only accepts 10" without attachment) that you want a blade for.

I got this to cut damaged engineering wood flooring. The flooring is over concrete so I didn't want to chance the expensive Festool blade. So glad I made the purchase, the cuts were just about perfect. After I was done, I was able to use this to break down plywood sheets. Not as good as the Festool blade, but I can buy 3 of these for the same price.

Was looking for a replacement blade about a year ago when my original Makita beam was blade started getting dull. Found the Oshlun blade on Amazon and resisted buying it at first due to the low price. I just ordered my second one after using the first one 6 days a week for 10 months. We cut large Western Red Cedar, cypress, fir and spruce beams all day long with this blade (both rips and cross cuts). This blade has never warped under heating (and we really heat this thing up some days). Good blade at any price.

Have done a lot of wood working projects over the years. Have done carpentry on houses. Have done fiberglass work for boats. This was my first foray into Aluminum/Metal cutting. Purchased a 16' X 16' Mechanical Pergola kit for my home and needed to trim the beams, louvers, posts for the install. Purchased a 12" Compound Miter saw from Northern tool and upgraded the blade to this 120tooth metal cutting blade and OMG it was good! Cut 1000lbs of aluminum and it was cutting just as good on the last cut as the first cut. Well worth the money for the quality of the cutting. Beware though cutting metal is nothing like cutting wood! Clamp everything and be sure to keep the items you R cutting firm otherwise you'll get into trouble. I quickly learned as several items kicked and I broke a 2 teeth from this blade but for the rest of the project it kept cutting like they were not even missing.

I was looking for a reasonably priced full-kerf blade for my 12" miter saw. I had been having issues with a big-name HATB thin-kerf blade deflecting, causing inaccuracies and in some cases actually grabbing the work. After checking out several alternatives I settled on the Oshlun as a kind of low-cost experiment mainly to see if a thicker blade would solve my problem. This one has a .134" kerf with a thick plate and no noticable runout. The results have been stunning. Besides the fact that the blade seems to cut truer with almost no drag, the cuts are clean both on top and bottom sides! We'll see if that keeps up as the blade wears but I have been delighted so far. My blade has C-3 carbide. I think the blade now comes in C-4, which would probably last longer. One thing to look out for is that the mass of this blade is greater than most, which will cause it to coast longer when shut down or put more strain on your blade brake if you have one. Oshlun has won my loyalty with a great product at a great price.

This is the third dado set I've bought over the years. The Freud that I'd used for well over five years needed replacing.

I bought the Oshlun after thinking about it for a while. I liked the Oshlun full-blade inner cutters. My previous versions had vane cutters on the inside with two carbide chipper points separated by 180°. Aligning the Freud stack required an inner chipper arrangement from experience to preclude nick-cuts and occasionally reshuffling the inside blade saw spindle balance. No knock on Freud ... the dado was worked hard and lasted a long time.

My first project for this Oshlun was on 14 4x6" half-lap joints. The Oshlun dado is noticeably heavier - more blade, more carbide tips. Noticeably tighter tolerances on the saws 5/8ths shaft. The tighter tolerancing extends to flatness. The blades arrive lightly oiled and oddly joined with a tight vacuum weld between the uber-flat blades.

The dado cut at max thickness was like a hot knife through warm butter.

Much better than expected. It's the best dado set I've owned.

I have found this dado blade to be excellent. The price was great, ease of use and setting up is far superior to the HF dado blade I returned after one of the shims jammed on the arbor of my Delta uni-saw and damaged the arbor threads on the 2nd use. That cost me $150.00 to for the purchase of a replacement arbor! Many customers complain that the storage box it comes with is not suitable. It is just a cardboard box. When mine arrived the box was broken on three sides. However the dado blades are very well packaged in foam and arrived with no damage. I simply made my own storage box from 1/2" plywood and utilized the foam packaging to safely store the dado blade.

I love Festool, I buy their sanding pads for my rotex 150, I think you can't beat their quality products. I have to admit, forking out $125 for a replacement blade from Festool seemed steep. Went for this blade instead and let me tell you, this blade cuts just as good as the festool one, can't tell the difference, go for it. P.S: I cut wood only, not sure, if that's the case for other materials. Really glad I found this on Amazon.

This blade turned my vintage metal cutting saw a beast. Using this blade in the vintage Zip Cut metal cutting saw, I test cut some 1/8" x 3/4" aluminum flats and was thoroughly impressed. The flats were cut with perfect and clean cuts that do not require any follow-up deburring. I then test cut a brass bar - 1" x 1/2" and the results were simply perfect.

I only wish I'd bought this blade sooner.

This is a great blade. I’m using it on a radial arm saw. Cuts are clean and accurate. The negative hook gives me much greater control when cross cutting with the radial arm saw because the blade isn’t so aggressive while traveling through the wood. When ripping “one by” pieces of pine or plywood I don’t have to push so hard and it allows me to feed the wood through at the optimum rate. It’s much safer than using a blade that’s intended for a table saw.

I've just installed it on my DeWalt DWS 782, so I can't speak to longevity. However, it works and the laser line is right on the money. Bonus points for including extra batteries. Also, the hardest part of installing it was the process I would normally have to follow for changing the blade on my saw. Lastly, make sure you tighten the bolt on the blade properly. I thought I tightened it enough without ham handing it, but once the blade brake turned on the blade broke most and kept spinning.

I was cutting 1:4 inch fiberglass panels and it performed very well cut as expected and was smooth. Checked after cutting and teeth was sharp

This is an excellent dado set that produces a true flat bottom dado. The number of chipper blades and shims enable very precise measurements. They are as good as dado sets costing much more.

I have an old 8" table saw, and NOBODY stocks, or even sells- that size, I shopped around to all the hardware and hardware box/super stores, (you know the twi I mean), and even Grainger could not get them!
When I went online, this was the only company that had 8" blades at a decent price, I found a couple others at 2 to 3 times the cost.
It cuts great, enough so that I got a 7.5" blade for my circular saw!

I used this blade to cut 1/4" diamond plate. I had about eighty feet in cuts to make. At first the blade cut the metal like butter and the finish edge on the cut was smooth. The finish edge began to deteriorate with use and after cutting about sixty feet of material the cuts began to become very difficult. I tried cleaning off a buildup of aluminum on the teeth but this didn't help and I considered the blade to be worn out. I then lubricated my cuts with cutting oil and I was amazed. The blade began to cut better than my very first dry cut and the finish edge was very smooth. I wish I had lubricated all of my cuts. It would have extended the life of the blade considerably. Be careful and use eye protection because aluminum chips will be flying. I used goggles to ensure that a chip didn't get up behind my safety glasses.

One of the best blades I've owned over the last 30 years.

I bought this blade in May of 2014, bolted it up to a 10" Dewalt crosscut saw and started cutting 3 x 5 aluminum extrusion and several other types of aluminum. I've also cut PVC, ABS, and soft woods with it. The only thing I ever do to it is run a bit of beeswax over the teeth and sides once every month or two.

3-1/2 years later, and that same blade is still bolted up and cutting like the day I bought it.... minus all of the pretty red paint of course. 🙂

It's a good value. Of course it's made in China. Be sure to order a lube stick to use with it. If you are cutting thinner material like angle or box tubing, get the 120 Tooth. If you are cutting heavier bar stock, large rounds, get the 80 tooth. I ran the 120 tooth on some 3"x4" 7075 bar stock and it wanted to plug up even with plenty of lube.

Purchased to use in Wood! Why? The 1" bore.

To explain, we have a 12" "Original Saw Company" Radial arm saw in the shop. The 12" blades we have tend to be deafeningly loud, the outer rim speed is so high.
To combat this, we use 10" blades thus reducing the outer rim speed a good deal. This was easy to do with my old Delta R.A.S. that had the arbor more common in 10" blades ( 5/8" ) .
Since upgrading to the "Original" with the 1" Arbor (proper for 12" blades) I have had a very hard time finding any non custom made 10" blades with 1" arbor,.. until this one.
It makes very clean cross cuts in pine and hard woods. No tear out, super smooth.

And it is Soooooo quiet in the big R.A.S. we can no longer hear it over the dust collection.

Other blade replacements I have found have a kerf to thin to clear the Dewalt tracksaw's riving knife. This Oshlun blade's kerf is wide enough to clear the knife and the resulting cut is excellent. It could use a bit more rake (tooth angle) to make the cut a bit easier, but overal this blade is a good replacement.

I bought this blade for my Stihl TS 420 block saw. Although I'm sure the manufacturer would call it ill advised to say the least, I've shoved this blade into wood with embedded steel plates and bands, rocks, dirt, you name it. If your segmented concrete blade or disc shouldn't be used to cut it, then this is the answer. If you have a demo saw/block saw, this blade is the necessary third for a complete collection, for with all three there is virtually nothing you can not cut. Be forewarned, this blade is not for the meek. It is not like a chainsaw. It makes a chain and bar seem like kid stuff. Sawzall for pre-school girls. This will grab ahold of and rip apart virtually anything it comes in contact with, and isn't so forgiving like the discs and segmented concrete blades. With that said, it is way easier to use than you might expect. Look closely and you will see the carbide tips are set at a slightly negative angle, so it doesn't rip the saw out of your hands as easily as you might expect. DEFINITELY have the full blade guard properly installed and angled to protect from the shrapnel, and be wearing proper leg, hand and eye protection because this thing removes serious chunks of whatever is unfortunate enough to come in contact with it. I've put alot of miles on mine already, and it is fine. I can tell it isn't as fast as it was new, but for what i've done to it, it is impressive. I highly recommend this blade for commercial applications by qualified operators. You will not be disappointed. I would caution DIY folks to be sure you are competent to safely operate such an aggressive machine and blade combination, and that such an extreme setup is necessary. It is neat, and it is kinda fun, but definitely not a toy.

After ruining countless jigsaw blades cutting aluminum planks for a large porch replacement project, I decided to investigate whether a circular saw approach would be faster and provider cleaner cuts. The porch planks were aluminum extrusions that were one inch thick and 6.5 inches wide. I used this Oshlun blade in a cordless lithium based circular saw from Porter Cable. It worked wonderfully, but must warn the user to wear eye and ear protection. The project moved along at least ten times faster than it would have otherwise.

I recently purchased the Oshlun LG-M01 Miter and Portable Saw Laser Guide for my miter saw, and I must say that it has been a game-changer for my woodworking projects. This laser guide has significantly improved the accuracy and precision of my cuts, making my work much more efficient and professional-looking.

The installation of the laser guide was straightforward and hassle-free. It fit perfectly on my miter saw and the alignment was easy to adjust to ensure that the laser line was accurate with my saw blade. Once installed, the laser guide provided a clear, bright line that helped me visualize exactly where my cuts would land, resulting in precise and clean cuts every time.

I particularly appreciate the portability of this laser guide. It is compact and lightweight, making it easy to transport and use on different job sites or workstations. The durability of the guide is also impressive, as it has held up well to regular use and has not required any adjustments or maintenance since I installed it.

Overall, the Oshlun LG-M01 Miter and Portable Saw Laser Guide has exceeded my expectations and has become an essential tool in my woodworking arsenal. I highly recommend this laser guide to anyone looking to enhance the accuracy and efficiency of their miter or portable saw cuts. It is a small investment that yields significant improvements in the quality of your work.

I was hesitant to buy this blade since there were no reviews to vouch for its quality.I am a professional trim carpenter and needed a blade that could last and cut cleanly.I decided to take a chance rather than spend three times more $ on the festool brand or one of the other alternatives out there.I have been extremely impressed with this blade and have found the blade indistinguishable from the festool in use and in long life between sharpenings.I am buying a couple more since I like to have several blades on hand at all times.

I needed to cut many aluminum cleats that were 34" down to 29.75" to fit on the back of the cabinets. I bought a DeWalt Atomic 4 1/2" saw during Xmas, and this blade was all I could find that would fit the saw. So I bolted this up and made my cuts with ease. Being too lazy to change blades, I use this blade to cut the wood rail buffers, and it cut the wood as good as the wood blade. After making about 20 cuts, the blade showed no signs of wear or loss of cutting power. The blade is very quick in speed and easy to control. Sure beat using a hack saw like I did last time. Kind of pricey, but time was not on my side. I searched all over the internet and Home Depot, but they only offered 7"+ blades.

I love this blade. I installed it in my cabinet saw and so far I've cut hardwood, plywood, and plexiglass without any issues. The surface that is left is super smooth - feels as if it were sanded by a 300+ grit sandpaper!
I can't comment on the longevity of the blade sharpness but after owning it for couple of months it's held up very well.

I had never cut aluminum. After some research I decided for safety reasons it was best to purchase a product designed for the job. Right tool for the job. I cut channelled aluminum 2" X 8" (Bleacher Seat or Plank). I saved the first cut so I could compare to my last cut. I made 90 cuts. The blade held up very well for my purpose. You have to cut slightly slower than you would cut wood, Although, as I neared the final cut, it seemed in my mind that the cutting ability of the blade was getting oh so slightly slower, but that is to be expected. There was no noticeable difference in quality of the 90th cut from the 1st cut. I think the blade will cut plenty more with no problem. There were no lost teeth or blade damage. Probable because aluminum is the product cut here, it leaves a large amount of debris. Probably no more than wood really, but because it is metal, it must seem like more because it won't lay flat on the ground after the cuts. You will want to wear eye, ear and leg protection. I am pleased with this product

Using this on a Makita demo saw. Had a cheaper(McGills Warehouse) blade with 80 teeth on it. The McGills blade heated up and warped the blade plate while cutting so it wasn't much use. Fewer teeth on this blade and the way the carbide attaches(big shoulder on the plate behind the carbide) will make this blade much more durable and usable. Haven't seen any blade deflection yet but there's no wood sap build up on it yet. Cuts fast, doesn't jump or bounce much(use light pressure with the low tooth count as it cuts very aggressively).

I have never used a saw blade designed specifically for plastic before so I wasn't sure what to expect but this blade goes through plexiglass like butter. It cuts 1/8" and 1/4" thick sheets leaving a decent edge ready for 220-400 grit sanding. No nicks, cracks, chipping or melting. If you need to cut plastic this blade will do the job.

Bosch CM10GD dual-bevel miter saw owner. If you purchase it on AMZ you can get the preinstalled laser guide for $80 more or without. I chose without, and after a year figured I'd spend the $20 on the separate module. This thing is great.

How to install: Seriously takes longer to write it up than do it. Unscrew two screws on the blade guard, unscrew (CLOCKWISE) main blade screw, put on laser, screw back in (COUNTERCLOCKWISE to tighten!) and replace blade guard screws.

MAYBE it took me all of 15 seconds. Maybe.

The laser line is exactly to the left of the kerf. The saw blade is exactly to the right of that line. If you're a half-blind half-fingered woodworker, position the line so it's just left of your offcut... and cut.

Why did I go a year without buying this... do yourself or your loved woodworker one a favor and get one of these. This was easier to install than any of the DIY projects i've done in ten years. I could gush for another hour.
