Description

The Switchback® step drill is your solution for precision hole cutting in a range of materials including metals, plexiglass, plasterboard, and plastics. It is designed to cut faster and last longer when performing repetitive hole cutting or enlargement for electrical, automotive, and sheet metal applications. The spiral flute design allows for faster cutting, and all but the largest sizes are compatible with the ¼” impact shank. Longer steps on the drill bit offer enhanced control and precision when cutting, and the 135-degree split point tip allows for faster penetration in every cut.
