MIL 3.9R0.05 L12 Anti-XN-60° KEUE CNC Carbide Boring Tool Stain
This MIL reverse‑thread small‑hole threading tool is built from solid tungsten carbide with premium high‑silicon coating. It features outstanding hardness and thermal stability, specially optimized for machining steel and stainless‑steel workpieces up to HRC40, widely used on Swiss‑type automatic CNC lathes.
Precision‑ground cutting edge delivers stable reverse internal thread forming inside tiny bores. It effectively resists built‑up edge and high‑temperature wear. Well‑tuned chip geometry guarantees smooth chip removal in confined inner‑hole space, securing consistent thread profile and dimensional accuracy.
A complete range of angle and size options are available to fit diverse reverse‑thread production tasks. Compact rigid shank adapts to limited small‑aperture working space. It reduces tool wear risk, prolongs service life, lowers defective rate and improves efficiency for mass‑produced miniature threaded parts.
