Dormer R458 HM High Performance TiAlN Coated Force X Drill Bit 5.4mm

Designed for precision and durability in the most demanding applications, the Dormer R458 HM drill bit delivers outstanding performance in stainless steel, high-tensile materials, and hardened steels up to 55 HRC. Its advanced TiAlN coating combined with a specialised point geometry ensures faster penetration, reduced heat generation, and exceptional tool life, making it the go-to choice for professional machinists and engineers.

- TiAlN multi-layer coating provides high hardness and thermal resistance, enabling dry or minimum-quantity-lubrication drilling

- 130-degree split point with a reinforced core geometry for accurate starting, reduced walking, and excellent chip evacuation

- High-performance carbide substrate with a fine-grained microstructure for superior edge retention and strength

- Optimised flute design promotes efficient swarf removal, minimising cutting forces and preventing built-up edge

- Manufactured to tight tolerances for consistent hole size and surface finish across batch runs

- Suitable for use on CNC machines, manual milling machines, and high-speed drilling applications

Whether you are drilling deep holes in tool steel or tackling tough aerospace alloys, this bit offers the reliability and speed your work demands.
