Dormer A520 HSS TiN ADX Stub Drill Bit 3.9mm Pack of 1

This stub drill bit delivers outstanding performance in demanding engineering applications, offering superior wear resistance and chip evacuation thanks to its advanced Titanium Nitride coating and ADX geometry. Designed for high-speed drilling in a wide range of materials including steels, cast iron, and stainless steel, it ensures consistent accuracy and extended tool life even under tough workshop conditions.

- Titanium Nitride (TiN) coating reduces friction and increases surface hardness, allowing faster cutting speeds and longer intervals between regrinds

- ADX (Application Driven eXecution) flute design provides excellent chip flow and reduces cutting forces, minimising breakthrough burrs

- Stub length geometry offers maximum rigidity and stability, ideal for precise, shallow hole drilling and CNC operations

- High-Speed Steel (HSS) substrate combines toughness with heat resistance, suitable for both manual and automated use

- 3.9mm diameter with a 118 degree point angle ensures clean starting and accurate centring

- Suitable for use with or without coolant; works effectively in ferrous and non-ferrous materials

- Manufactured to Dormer's exacting tolerances for reliable, repeatable performance across multiple workpieces

Perfect for professional engineers and machinists who demand precision and durability from every drill bit.
