Key specifications

Selecting the right option

Built from VHM, these tools deliver superior hardness and wear resistance — the right choice for high-speed machining, hard materials and demanding production runs. The TiCN surface treatment reduces friction, improves chip evacuation and extends service life compared with uncoated tools — particularly valuable in harder or abrasive materials. The 140°° point angle is optimised for the materials and applications this range is designed for. Match the drill diameter to your required hole size and ensure adequate feed rate and coolant for best results. Maximum cutting depth is rated at 3xD — keep within this limit to maintain hole quality and avoid overloading the tool.
