MIL 1.4R0.03 L4 Anti-XN-60° KEUE CNC Carbide Boring Tool Stainless
This MIL reverse-hand small-bore internal threading tool features solid tungsten carbide base with premium high-silicon coating. Engineered for steel and stainless steel workpieces up to HRC40, it delivers exceptional cutting rigidity for precision micro threading on Swiss-type automatic lathes.
Precision-ground 60° thread edges guarantee standard tooth profiles and smooth chip evacuation in tight inner bores. The wear-resistant high-silicon coating effectively suppresses built-up edge, ensuring stable pitch precision and excellent surface finish throughout long continuous machining.
Available in multiple sizes and angle options to meet diverse processing needs, its compact reverse structure fits narrow inner-hole space ideally. It reduces tool change downtime, extends service life and greatly lifts overall efficiency for mass production of miniature threaded components.
