Product Introduction
Cutting square holes for electrical boxes the old way takes forever — mark it, cut it, chisel it, clean it up. This tool does it in one step. Mount it to your hammer drill, position it over the mark, and drill. The hole comes out clean, square, and perfectly sized for 86-type junction boxes. No measuring twice. No chasing edges with a chisel. One hole, one try, done.
