Contains: 1" and 2-1/8" 4/6 Tooth Hole Saw, 3/8" Hex Arbor, Arbor Spacer and Arbor Adapter.
This kit includes everything you need to install a door lock. It consists of a 1 inch hole saw, a 2-1/8 inch hole saw (both with 4/6 tooth configuration), a 3/8 inch hex arbor, the arbor spacer and adapter. The 4/6 tooth design with varying tooth sets and gullet depths provides a more efficient chip clearance and less heat build up, and requires less feed pressure to accomplish the drilling of the holes.
