MIL 1.9R0.03 L6 Anti-XN-60° KEUE CNC Carbide Boring Tool Stainless
This MIL reverse small‑bore internal threading cutter adopts premium solid tungsten carbide with high‑silicon hard coating. Designed for left‑hand inner thread machining of micro holes, it processes steel and stainless steel up to HRC40, ideal for precision production on Swiss‑type CNC lathes.
Precision‑ground thread profiles ensure standard tooth shape and smooth chip removal in confined inner‑bore spaces. The wear‑resistant high‑silicon coating effectively suppresses built‑up edge, delivering stable pitch accuracy and excellent surface finish for long‑running continuous machining.
Available in various specifications with 60° and 55° angle options, its slim rigid shank fits narrow machining space perfectly. It prolongs tool service life, cuts tool‑change downtime, and greatly boosts overall efficiency for mass manufacturing of miniature threaded components.
