MIL 7.9R0.1 L22 Anti-XN-60° KEUE CNC Carbide Boring Tool Stainless
This MIL reverse‑thread boring tap is built from solid tungsten carbide with premium high‑silicon coating. It targets reverse internal thread machining for stainless steel and steel parts up to HRC40 hardness. The high‑rigidity shank fits Swiss‑type automatic lathes for small‑hole internal thread production.
Precision‑ground 60‑degree thread profile delivers sharp cutting edges for reverse thread forming. It keeps stable cutting performance under heavy load, effectively reduces tool wear and built‑up edge. Smooth chip removal inside confined small bores ensures consistent thread dimensional accuracy.
Various angle‑specification options satisfy diverse reverse‑thread machining requirements. Compact tool geometry adapts to limited inner‑hole working space. It lowers defective‑part rate, extends tool service life, reduces frequent tool‑changing downtime and boosts mass‑production efficiency of miniature threaded components.
