Hex-Shank Drill Bits
Hex-shank drill bits have a hexagonal shank that provides maximum surface contact with a drill chuck on handheld power tools. This prevents the bits from slipping in the chuck during drilling. Drill bits with a hex shank insert into a standard 3-jaw drill chuck or a drill chuck specifically designed for hex shanks.
