Dormer A002 HSS-TiN Coated Jobber Drill Bits, 4.20mm (Pack of 2)

The Dormer A002 Metric HSS-TiN Coated Jobber Drill Bits are designed for professionals seeking high-performance cutting tools. Each bit features a pointed web and fluted tip design, ensuring efficient cutting with reduced axial force for accurate centring. The optimised web design enhances strength and rigidity, improving the feed of the drill bit, while the flutes promote efficient chip formation and evacuation.

These drill bits include visible, in-situ tool markings for easy identification. The optimised helix angle provides greater stiffness across the diameter range, ensuring precision and durability. The bright body enhances cutting performance on ductile materials, and the Titanium Nitride (TiN) coating resists flank and crater wear. This low-friction coating also allows for increased cutting speeds, making these bits ideal for demanding applications.
