Dormer A520 HSS TiN ADX Stub Drill Bit 4.4mm Pack of 1

The Dormer A520 is a 4.4mm stub drill bit made from high-speed steel with a titanium nitride coating for improved wear resistance. At 58mm long, its compact length provides extra rigidity, making it suitable for confined spaces and applications requiring precision. The bit features a 130° split point to reduce walking and ensure quick starts, with ADX geometry designed to optimise chip removal. It works across steel, aluminium, and plastics. This is a single bit conforming to DIN 1897 standard, intended for general-purpose drilling where durability and accuracy matter.
