Vari-Bit Step Drill Bit, 3/16-Inch to 1/2-Inch Range, 1/4-Inch Shank

This product is a step drill bit designed to drill multiple hole sizes in thin materials using a single tool. It covers a 3/16-inch to 1/2-inch hole diameter range and features a 1/4-inch shank with a three-flat design to prevent slipping in drill chucks.
Manufactured from high-speed steel, the drill bit incorporates a double-flute cutting geometry for faster, burr-free drilling and longer tool life.
It also features a self-starting drill point that allows for drilling without pre-punching, enabling smooth and precise hole starts.
