Key specifications

Selecting the right option

This range is manufactured from PM-HSSE V3 for enhanced heat resistance and longer tool life when machining harder steels, stainless grades and tough alloys. The TiCN surface treatment reduces friction, improves chip evacuation and extends service life compared with uncoated tools — particularly valuable in harder or abrasive materials. Select the correct Metric thread form and size to match your fastener specification. Verify thread tolerance class 6HX meets your assembly requirements. Maximum cutting depth is rated at 2xD — keep within this limit to maintain hole quality and avoid overloading the tool.
