Dormer A520 HSS TiN ADX Stub Drill Bit 3.4mm Pack of 1

This drill bit delivers outstanding penetration rates and extended tool life, thanks to its advanced Titanium Nitride coating and innovative ADX point geometry. Designed for stub-length drilling in a wide range of materials – including steels, stainless steels, and cast irons – it offers exceptional rigidity and positional accuracy, reducing the need for centre punching and minimising walking on curved or uneven surfaces.

- Titanium Nitride (TiN) coating significantly reduces friction and heat buildup, enabling higher cutting speeds and longer intervals between regrinds

- ADX self-centring point geometry allows drilling without a centre punch and improves chip formation for cleaner holes

- High-speed steel (HSS) construction provides a robust balance of toughness and wear resistance for reliable performance in production environments

- Stub-length design maximises stiffness, reducing deflection and improving hole straightness in shallow drilling applications

- 3.4mm diameter precision ground to tight tolerances for consistent, accurate results every use

- Suitable for use with coolant or lubrication to further extend tool life and surface finish quality

Perfect for machinists and engineers who demand high productivity and precision in repetitive drilling tasks.
