Vari-Bit Step Drill Bit, 1/4-Inch to 3/4-Inch Range, 3/8-Inch Shank

This product is a step drill bit engineered for drilling multiple hole sizes in thin materials using a single tool. It provides a 1/4-inch to 3/4-inch hole diameter range and features a 3/8-inch shank with a three-flat design that prevents slippage in drill chucks.
Constructed from high-speed steel, this bit features a double-flute cutting design for fast, burr-free hole drilling with extended tool life.
It includes a self-starting drill point that eliminates the need for center punching, allowing for precise and easy starts.
