Dormer A520 HSS TiN ADX Stub Drill Bit 3mm Pack of 1

This high-performance stub drill bit delivers exceptional accuracy and extended tool life, making it the ideal choice for demanding drilling applications in a wide range of materials. Its optimised design ensures clean, precise holes with reduced cycle times, even in challenging production environments.

- Titanium Nitride (TiN) coating reduces friction and increases surface hardness, allowing for higher cutting speeds and improved chip flow

- High-speed steel (HSS) substrate provides excellent toughness and wear resistance for consistent performance

- ADX geometry with a 140° split point enables self-centring and reduces thrust, minimising walking on contact

- Stub length design offers maximum rigidity, reducing deflection and improving hole accuracy in shallow-depth drilling

- Suitable for use on steel, stainless steel, cast iron, and non-ferrous metals, including in automated and manual operations

- Precision-ground flutes enhance chip evacuation and reduce heat build-up during cutting

- Pack of 1, 3mm diameter, manufactured to Dormer’s exacting quality standards

Ideal for professional machinists and maintenance teams who demand reliability and repeatability from their tooling.
