Vari-Bit Step Drill Bit, 7/8-Inch to 1-3/8-Inch Range, 3/8-Inch Shank, 5-Step Design

This product is a step drill bit designed to drill multiple large hole sizes using a single tool. It covers a 7/8-inch to 1-3/8-inch hole diameter range across 5 stepped increments and features a 3/8-inch shank with a three-flat design for anti-slip performance in drill chucks.
Manufactured from high-speed steel, this bit incorporates a double-flute cutting geometry to deliver faster drilling, burr-free finishes, and extended tool life.
It also includes a self-starting drill point for fast starts without center punching, allowing for smoother hole enlargement and consistent drilling performance.
