Key specifications

Selecting the right option

Built from VHM-ULTRA, these tools deliver superior hardness and wear resistance — the right choice for high-speed machining, hard materials and demanding production runs. The Aldura surface treatment reduces friction, improves chip evacuation and extends service life compared with uncoated tools — particularly valuable in harder or abrasive materials.
