MIL 3A55 L15 Anti-55° KEUE CNC Carbide Boring Tool Stainless St
This MIL series reverse‑thread boring tap is made of solid tungsten carbide with high‑silicon coating. It delivers outstanding wear resistance for machining steel and stainless‑steel workpieces up to HRC40. The robust integrated structure greatly improves rigidity for small‑hole internal reverse‑thread processing tasks.
Optimized 55‑degree thread angle geometry fits 0.5‑1.0 thread pitch range perfectly. Sharp precision‑ground cutting edge ensures stable chip removal inside narrow inner holes. It forms clean reverse‑thread profiles and maintains consistent thread accuracy during continuous CNC turning production.
Designed specially for Swiss‑type lathe small‑hole reverse‑thread machining, it covers multiple shank sizes and working‑length options. Reliable service life lowers tool‑replacement frequency, reduces operation downtime and effectively raises productivity for miniature precision component mass‑production.
