The Irwin Miter Saw Laser Guide allows you to convert your miter saw into a precision laser-guided power tool! It's simple to install by replacing the saw's outside blade washer with the self-aligning Laser Guide. The guide projects a clear line just to the left of the cut, and turns on and off automatically at 400 RPM.
