Dormer A022 HSS TiN Coated Stub Drill Bit 4mm Pack of 10

Crafted for precision and durability, this 4mm stub drill bit delivers exceptional performance in demanding materials. The titanium nitride (TiN) coating reduces friction and heat build-up, enabling faster drilling speeds and a cleaner finish while extending tool life significantly. Designed for use in steel, cast iron, and non-ferrous alloys, it offers consistent, accurate holes with minimal wander. The straight shank ensures a firm grip in standard chucks, and the stub-length geometry provides added rigidity for controlled, vibration-free drilling in tight spaces.
