Dormer A022 HSS TiN Coated Stub Drill Bit

The Dormer A022 HSS TiN Coated Stub Drill Bit is a high-performance drilling solution engineered for precision and durability in demanding applications. Constructed from premium high-speed steel (HSS) with a titanium nitride (TiN) tip coating, these drill bits deliver exceptional heat resistance and extended tool life, even under intense working conditions.

The stub length design provides superior rigidity, minimising deflection during use and making these bits ideal for high-precision tasks in both professional workshops and home DIY projects. The 135° split-point geometry facilitates easy self-centering and eliminates the need for pre-drilling, ensuring accurate hole placement when drilling by hand or machine.

Compliant with DIN/ANSI standards, the A022 series features a straight cylindrical shank, standard spiral flute design, and right-hand cutting rotation. Optimised for 2.5×D drilling depth without pecking, these bits excel when working with steel, cast iron, and other tough materials. Available in diameters from 0.5mm to 16mm in packs of 1, 5, or 10, depending on size.
