Dormer HSS TiN Coated Stub Drill Bit 4.1mm Pack of 10

Product Description

A compact, 4.1 mm stub drill bit made from high-speed steel, treated with a titanium nitride coating to boost surface hardness and wear resistance. The 135-degree split point provides self-centering action, reduced thrust, and easier penetration, helping to achieve accurate holes with a cleaner surface finish. Suitable for use in both machine-mounted and hand-held drilling setups, and sold as a pack of ten. The TiN coating extends tool life and helps maintain hole quality over multiple cuts in appropriate materials.
