Product Selling Points

This MIR 7A60 L22 R0.2 small-bore internal threading tool is built from solid tungsten carbide substrate with advanced black high-hardness wear-resistant coating. Featuring 7mm rigid shank, 60° thread angle and 22mm cutting depth, it reliably machines HRC50 steel and stainless steel on Swiss-type micro lathes.

Precision-ground 60° thread cutting edges with R0.2 nose radius ensure accurate tooth profile and smooth chip evacuation in narrow confined inner bores. The black high-performance coating reduces friction and built-up edge effectively, maintaining stable dimensional precision and fine surface finish in long heavy-duty production runs.

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