Key specifications

Selecting the right option

Manufactured from PM-HSS Co, this range offers an excellent balance of toughness and wear resistance suited to general-purpose production and maintenance work. 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 Unified thread form and size to match your fastener specification. Verify thread tolerance class 2BX meets your assembly requirements. Maximum cutting depth is rated at 1.5xD — keep within this limit to maintain hole quality and avoid overloading the tool.
