OSHLUNLG-M01 Miter and Portable Saw Laser Guide, Miter & Portable Saws , grey

This Portable Saw Laser Guide has completely transformed my woodworking projects. As someone who values accuracy, I was blown away by how effortlessly it aligns cuts every single time. The laser beam is bright and easy to see even in well-lit workshops, eliminating the guesswork of traditional marking methods.Setup took less than 2 minutes—it clamped securely onto my saw without any wobbling, and the adjustable angles made angled cuts a breeze. I’ve used it on plywood, hardwood, and even PVC piping, and the results are consistently razor-sharp. No more wasted materials from misaligned cuts!What really stands out is the durability. The build quality feels industrial-grade, yet it’s lightweight enough to toss in my toolbox for on-site jobs. The battery life is impressive too; after weeks of use, I still haven’t needed a replacement.Whether you’re a DIY enthusiast or a pro contractor, this gadget is worth every penny. It’s saved me hours of frustration and elevated the quality of my work. Don’t hesitate—buy it now and thank yourself later!"

I've got a couple of these laser guides on miter saws. One of another brand I added, one came with the saw. I put this one on my radial arm. It's the best of them. The line is finer than the others and it falls EXACTLY on the edge of the cut. What you see is where it cuts. The other washer lasers and another projected laser line I have require some interpolation and guessing due to the misalignment and width of the fuzzy laser line. This one illuminates the edge of the uncut wood with a very narrow and crisp line and doesn't "fall over" into the kerf at all. I'm using it with the RAS to cut dados in cabinet boxes. It's accurate enough that I can cut half the groove, maxing out the the cross cut of the saw,- flip it around, line up the laser with the pencil mark and the other half of the groove, and finish the cut. Saves a lot of measuring and setup.

It works exactly like it should. However I HIGHLY recommend getting a 1"+ diameter washer to place on the outside to seat the bolt on. The center of this laser guide isn't very strong, and the bolt will eventually squeeze through without a washer to distribute the pressure. Discovered this when my blade came loose out of nowhere.

Works perfect. I should have bought one of these years ago.

Works on My Dewalt DWS779 miter saw.

I was a little concerned about the brightness after reading several reviews. Ordered anyway. I have LED lights on both sides of my miter saw and the laser showed up just fine. I'm not sure about durability but if I have a problem later I'll add a new review. Hardest part of installation was Loosening the Arbor nut.

I bought two of these to add to a Ryobi TS1343L 10 Inch Miter Saw, so that I can have a laser guide line on both sides of the blade. There is a company who sells dual laser guides, but they do not list this saw as compatible, and I read reviews for the Oshlun brand in which an Oshlun company representative is quoted as saying theirs are brighter than other brands. Since the one Ryobi uses is all but invisible in bright daylight, I was hoping to improve the situation.The first thing I did was remove the saw blade, and mount one of these Oshluns next to the OEM Ryobi laser guide, and run the saw. The lines are identically bright. I do not see any more brightness from the Oshlun at all.There is one thing the Oshlun LG-M01 has going for it that the Ryobi laser guide cannot do. The Oshlun model will work no matter which way you mount it on the arbor. The Ryobi model that came on the saw MUST be mounted with the label side out, or the laser doesn't come on when it spins. Because I wanted to use dual guides, I need to have one replace the inner blade washer, and so must be mounted in reverse to keep the laser close to the inside of the blade.Note the round hole on the face of the Oshlun in the picture shown in this review. Ryobi uses a "D" shaped hole all the way through the guide. The back side of the Oshlun has a similar modified hole which is about 7/16" by 1/2" rectangle with rounded corners, to allow it to slide onto the flats on a typical 5/8" arbor shaft. It is their intention this guide be mounted right under the head of the blade bolt, so the smaller round hole on the face of the device works fine if used singly as intended. But to make it slide to the inside of the blade, I had to machine the round hole you see in the picture to match the contour of the rectangular hole on the back side. Once I did that, it slid into place nicely, with the label side toward the motor, placing the laser along the inner blade edge.I then mounted the blade and the Ryobi laser guide, and was able to use the OEM bolt, with plenty of threads screwing into the shaft. It works very well, showing a line on either side of the blade now when the motor is started. There is a slight difference in the positioning of the Oshlun's line, such that after a straight cut is made in the stock, the inner laser line falls IN the kerf, up against the inside bottom edge. The Ryobi guide's line on the outside of the blade remains on top of the edge of the cut after it is made. I was able to correct most of this by adding a paper shim washer between the blade and the Oshlun guide, much as you would do to fine-adjust the width on a set of dado blades. Because this worked with the original Ryobi guide, I did not open the second Oshlun guide, and will keep it as a spare.I was hoping to see a lot brighter line from the Oshlun brand, to make it easier to work in the sun, but the brightness of the 2 lines is equal. It is fine for indoors, even in a brightly lit shop. But for bright sunlight the laser lines are only the tiniest bit visible if you look very hard to see them. Oddly, the Ryobi brand uses a pair of LR44 cells, and the Oshlun uses 3 of them. When I saw that I thought it might be brighter, but it is not.
