Ken Yi St-Mir 6A60 L15 High Hardness Stainless Steel Thread Knife Oblique Positioning Internal Thread Drill Bits 6mm Shank 60mm
This ST-MIR 6A60 L15 small-bore internal threading cutter features a bevel-positioning structure that ensures precise repeated clamping without tool offset reset. Built from solid carbide with premium nano-blue hard coating, it offers outstanding rigidity for micro internal threading of stainless steel on Swiss-type CNC lathes.
The precision-ground thread cutting edge ensures standard thread profiles and smooth chip removal in confined inner bores. The wear-resistant nano-blue coating effectively suppresses built-up edge, delivering stable pitch accuracy and fine surface finish when machining high-hardness steel and stainless steel workpieces.
Its slim compact profile perfectly fits the limited working space of small-aperture internal threading. It cuts tool-change downtime, reduces tool consumption, maintains consistent quality in mass production, and boosts overall efficiency for manufacturing miniature precision metal parts.
