RUKO SPB-DIN345-12.5mm-HSS Morse Taper Twist Drill Bit, DIN 345, HSS, 12.5 mm

Precision-ground from solid HSS to DIN 345, this 12.5 mm twist drill bit features a Morse Taper MK1 shank for secure, high-torque mounting in stationary drilling machines. Its 118° point angle and right-hand cutting geometry deliver clean, accurate holes in steel, cast iron, non-ferrous metals, and plastics.

Overview

The RUKO SPB-DIN345-12.5mm-HSS is a professional-grade twist drill bit engineered for reliable performance in demanding workshop environments. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, the bit is ground from solid for superior concentricity and edge retention. The Morse Taper shank (MK1) ensures a positive, self-locking fit in matching machine spindles, minimizing slippage under load.
