RS-1 Laser Cutting Guide/Special Father's Day Gift

I got this product in place on my saw (a DeWalt 713 "type 2," the version in which DeWalt omitted the access panel that formerly allowed owners to install DeWalt's own laser or LED guide) with no problem at all. Like another reviewer, I was installing a new blade (a Freud LU91M010, which I LOVE) so adding the laser guide was a piece of cake.Except that it did not work.I tried installing new batteries, changing how I put it back together...nothing. I'll be returning it to Amazon for exchange, because fits fine and i know from another review that it can work with my saw. Hoping for better luck next time...EDITED TO ADD: returned to Amazon for replacement. Return was easy and quick, and the new laser guide is amazing. I can't believe it was only $10. It works beautifully, was incredibly easy to install, and is a huge upgrade to my saw. I am now a very satisfied customer. I am changing my rating from one to five stars.

These are great quality, easy to install cutting guides. I installed one on the outside of my Dewalt DW708 12" compound miter saw, but had ordered two and intended to install on both sides of the blade. Well, the one worked so well that I decided to modify the other one as needed to fit on the inside of the blade. It had U shaped flats on the 5/8" opening to so I had to drill it out to fit the 5/8" round shaft on the inside. I removed the original mandrel and had to install three 5/8" x 1" machine washers to space it out like the original mandrel fit. I had to slightly thin those three washers to get the correct depth so that the outer laser with the flats would grip the drive flats on the shaft with the retaining bolt installed. Got it to fit and it works Fantastic!! Both lasers project onto the wood and outline the kerf perfectly on both sides of the blade. Now it's a breeze to use the saw from both directions!

works very well, no alignment needed just remove the bolt and washer on your saw and replace washer with this, only issue I had, was I put it on a miter saw, the laser beam is all diffused because of the plastic safety shield. so I have to start the saw and lower it until the laser is clear of the protector. then it shoots a nice clear beam to line up on. the other thing is that the laser is wider than the washer so the bolt stuck out further than before and the housing wouldn't fit right. so I had to grind the head of the bolt a bit. the only reason I don't give it a 5 star is it takes 3 button cell batteries, I find those kinds of batteries don't last and are way to expensive to replace all the time.

This is totally useless. The line is so dim that it is not visible in my garage with the door open. I thought that the batteries that came with the device may be bad so I bought a new set of batteries but the line is still so dim that it is not useable. Unless you plan to cut your wood in the dark (I would advise against this), do yourself a favor and avoid this product.

I added this to my 10" Hitachi miter saw in about 5 minutes. Nothing much to do - unscrew back, add included batteries, replace washer on the left of the blade with the RS-1. I've posted a picture of the unit when I first started it up.I purchased this on Amazon for $14.95, but it is listed under a slightly different description at $21 on Amazon. I think this may cause some confusion, since the specs are not stated for this particular listing ... anyway here they are:1. This product is the Infiniter RS-1 (I've posted pictures of the unopened carton)2. It fits 5/8" arbor with squared end and internal threading (most saws, particularly at the lower end like mine)3. It is activated on/off by centrifugal force (turns on when the blade is spinning)4. The insides are very simple -- a laser, 3 batteries, centrifugal switch, and small board (I've posted a picture of the inside of the unit)5. When you take off the washer that came with your saw, tape it to your user manual; you will be less likely to lose it (picture added)

For the money, this works fine. I am buying two more because they are worth it for my uses.Installed on 10" Harbor Freight sliding chop saw and DeWalt Cordless DW939 circular saw.On the HF chop saw the laser is not as bright as I would like and not visible in direct sun light. The line is just slightly to the left of cut, about the width of the light but easy enough knowingly adjust for. It's not a high quality saw either, plenty good enough.Install easy.On the DeWalt the laser is easier to see (closer to the materials) and lines up to the actual cut line nicely.Install a little tricky because the arbor on the DeWalt is too small. Once centered and tightened it hasn't moved after a few hours of use, yet.Next two going on another chop saw and corded circular saw.

The laser line appears on the work piece (about) 1/16" to the right of the cut edge. This occurs on standard kerf carbide tipped saw blades and is more significant on thin kerf blades. Not the level of precision I had expected.The arbor on my saw had a flat only on one side, I filed a second flat to allow the laser to fit the arbor. The bolt hole in the laser was smaller than the threads on my bolt. I drilled the bolt hole in the laser to allow the bolt to pass through. I did not mind making the modifications but I am disappointed that the laser line appears "so far" from the actual cut line.

I have an older model Pro-Tech 10 inch compound miter saw, model 7207. I ordered the Rs-1 laser cutting guide for this saw and it fit as if it was custom designed for it. The instructions were clear and easy to follow, the installation was quick (taking less then 5 minutes), the laser beam is bright, and the cost with shipping was less than $15. The beam is extremely accurate. I purchased the guide to aid in the accurate cutting of over 80 feet of crown molding. I was able to cut pencil marks in half. I would highly recommend this product. A great buy at a great price.
