Saddlemakers Groover: Heavy duty version of the groover on next page, with a blade that cuts a slightly wider groove. But the neat thing about this one is the easy adjustment feature! No screw driver needed, just loosen the chuck with your fingers, position the blade and re-tighten! Makes a clean groove from 1/16" to 1-1/2" from edge. Blade included. Item #011-806900.
