Dormer A520 HSS TiN ADX Stub Drill Bit 8.2mm Pack of 1

This drill bit delivers exceptional performance and longevity in demanding metal drilling applications. Its short, rigid stub length provides superior stability and reduced deflection, making it ideal for producing accurate holes in tough materials such as stainless steel, alloy steels, and high-strength steels. The premium Titanium Nitride (TiN) coating dramatically reduces friction and heat build-up, enabling faster cutting speeds and longer tool life compared to uncoated bits. Designed for professional use, this bit ensures consistent hole quality and minimises reworking.

- Titanium Nitride coating for enhanced hardness, wear resistance, and reduced cutting friction

- HSS (High-Speed Steel) substrate for toughness and resistance to high drilling temperatures

- ADX (Advanced Drill Geometry) point optimised for self-centring and reduced thrust, improving positional accuracy

- Stub length design increases rigidity and allows higher feed rates with less chatter

- 8.2mm diameter suitable for precision clearance and tapping preparation

- 118 degree point angle with split point for effective chip evacuation and no wander on entry

- Suitable for use in both manual and CNC drilling operations

- Pack of 1 with individual packaging for protection

The Dormer A520 delivers consistent, high-quality results in industrial environments, offering excellent value for demanding drilling tasks.
