Product Selling Points

This MIR 4A60 L10 R0.12 internal threading tool adopts solid tungsten carbide substrate with premium black high-hardness coating. With 4mm shank, 60° thread angle and 10mm depth, it reliably processes HRC50 steel and stainless steel micro threads on Swiss-type lathes.

Precision-ground 60° thread edges with R0.12 nose radius ensure accurate tooth profile and smooth chip evacuation in ultra-narrow inner bores. The advanced black coating effectively reduces friction and built-up edge, maintaining stable precision and fine surface finish in continuous production.

Its compact rigid shank perfectly adapts to the limited working space of tiny small-bore workpieces. Enhanced wear resistance prolongs tool service life, cuts tool-change downtime, and greatly boosts mass production efficiency of miniature threaded steel and stainless steel parts.
