Key specifications

Selecting the right option

Manufactured from HSS, this range offers an excellent balance of toughness and wear resistance suited to general-purpose production and maintenance work. The TiN surface treatment reduces friction, improves chip evacuation and extends service life compared with uncoated tools — particularly valuable in harder or abrasive materials. The 90°° 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.
