Dormer A022 HSS TiN Coated Stub Drill Bit 9.9mm Pack of 10

Crafted for precision and durability, this pack of ten Dormer A022 stub drill bits delivers outstanding performance in demanding drilling applications. The titanium nitride (TiN) coating significantly reduces friction and heat build-up, enabling faster cutting speeds and extended tool life even in tough materials such as stainless steel and alloy steels. The stub-length design provides exceptional rigidity and reduces deflection, making it ideal for accurate hole making in tight spaces or when working with hardened workpieces.
