RUKO 1000027010 HSS-G Twist Drill Bit 14.0 mm DIN 338 Cross-Ground

Drilling precise holes in metal, wood, or plastic can be a challenge with ordinary bits that wander or wear quickly. The RUKO 1000027010 twist drill bit solves this with a cross-ground split point that starts on contact without center punching, and HSS-G high-speed steel that stays sharp longer. This 14.0 mm bit is ground from solid to DIN 338 standards, giving you accurate holes and a long service life in demanding workshop tasks.
