The DW7187 DEWALT Miter Saw Laser System provides an accurate adjustable laser line that allows the user to adjust line to the left or right side of blade. The bright laser line delivers enhanced visibility in low and high light locations while the diode is positioned in an optimum location to provide long-term durability while keeping the laser diode clear and visible. The On / Off switch allows the user to operate the laser without the blade spinning and since it is powered by the saw there is no need for batteries. The DW7187 is designed exclusively for use on the DW715, DW716 and DW718 DEWALT 12 in. Miter Saws and will not fit any other DEWALT miter saw or any other miter saw brand.

Rated 5 out of 5 by Makes using your DeWalt mitre saw a breeze! Bought one a few years ago for my DW718 sliding compound mitre saw. Makes it almost mindless to make accurate cuts every time, whether I'm doing framing, decks, trimwork, or custom cabinetry. If you have a DeWalt mitre saw, this mod is for you! (Just check the list of compatible saws!) September 6, 2009
Rated 4 out of 5 by Once set up it is very handy. and the line is clear and easy to read March 17, 2009
Rated 5 out of 5 by Should Have Bought This Years Ago! This is an adjustable laser guide that can be set to either side of your blade. While the instructions are okay and clear, I chose to set the laser up myself, having worked with lasers in industry. Attached is a picture of my DeWalt chop saw; guard retracted. Shop lights off. The laser beam is set just skimming the left surface of the bade lighting up all the teeth. Way cool. One can even check their blade runout with it! Picture doesn't capture it. Using it outside, the laser is hard to see in direct sunlight, but otherwise fine. Plan accordingly. Working after dusk can treat you to an amazing light show. Adjustments are straight forward once you get the hang of it; however, setting the cut line to the right side does max out the adjustments and might be a concern with fatter kerf blades. I treat all my power tools with the same respect as a firearm so I love the trigger lock. This is a well thought out precision (for woodworking) piece. I have used laser guides on other makes; this one is among the best. I kick myself for being "too cheap" all these years sticking to my speed square and pencil. Wish I had bought it years ago. Really speeds up one's accuracy and productivity, especially in nested cuts. December 11, 2014
Rated 1 out of 5 by Didnt work with Dewalt Miter Saw 716 I am sure this is a great product, but couldnt use it on my Dewalt Miter Saw DW716. Before you purchase this laser or the LED work light, look at the top of the yellow handle on your miter saw. If you have a small rectangular access panel with two screws that attach it to the yellow handle (should be right next to the black handle you can lift the saw with), then the laser and the worklight is compatible with your miter saw. If you do not have an access panel like mine then you are out of luck for these products. August 20, 2014
Rated 1 out of 5 by Does not work with the newest version on the DW715 Contrary to what it says on the packaging, this does not work with all DW715 miter saws. The newest version of the DW715 is series 3, and this is incompatible with it. It doesn't say that anywhere on the packaging, and you can't tell which version of the saw you have until you look at the saw itself. I contacted DeWalt and they confirmed this. They don't have a solution at this point and they say they are working on a new laser, but as of now, nothing. I'm very disappointed in both DeWalt and Home Depot for selling a product with inaccurate and misleading labeling, especially since it's been pointed out and they are aware of it. September 16, 2014
