MIL 3A55 L10 Anti-55° KEUE CNC Carbide Boring Tool Stainless St
This MIL 3A55 L10 reverse-hand small-bore threading tool adopts solid tungsten carbide with premium high-silicon hard coating. With 55° thread angle and 3mm shank, it is tailored for reverse internal threading of HRC40 steel and stainless steel in micro bores on Swiss-type CNC lathes.
Precision-polished 55° thread cutting edges guarantee accurate tooth profile and smooth chip removal in narrow inner-hole spaces. The wear-resistant high-silicon coating effectively reduces built-up edge, maintaining stable thread precision and fine surface finish in long-term continuous production.
Its compact reverse tool body perfectly adapts to limited micro-bore machining space. It prolongs tool service life, cuts tool-change downtime, and notably boosts overall manufacturing efficiency for mass production of miniature reverse-threaded precision parts.
