7/16 COBALT HYPER-STEP REDUCED SHANK MECHANIC'S LENGTH DRILL BIT DBCHS28 | eBaydiy Tools

SUPERIOR DESIGN. Matco Exclusive Patented Cobalt Hyper-Step set is made from the strongest material tough enough to drill through the hardest jobs like stainless, grade 8 fasteners, hardened alloys and cast irons
MECHANIC’S LENGTH. Approximately 75% the length of traditional drill bits for increased drill bit rigidity and improved tight space access
ELIMINATES THE NEED FOR PILOT HOLES. Patented Hyper-Step design in large sizes eliminates the need for up to two pilot holes that traditional drill bits require
REDUCED SHANK. Designed to fit both 3/8\” and 1/2\” drill chucks with three-flatted shanks on both sizes below 3/8\” and on the 3/8\” reduced shank sizes up to 1/2\” to prevent slipping
INNOVATIVE. The multi-stepped tip acts like a step drill, allowing for laser like holes through sheet metal and prevents walking on curved surfaces
