Bosch BL21A
Bosch Black oxide metal drill bits have been designed to satisfy contractors, electricians and other pros who need solid, reliable bits for general application drilling in wood, plastic and light-gauge metal. The split-point tip has been engineered for no-skate starts and clean, accurate holes. The bit provides longer life than standard drill bits, thanks to the tip design and black oxide coating. The three-flat shank design on bits 3/16 in and larger promotes better gripping and guards against slipping.
