MIL 5A60 L22 Anti-60° KEUE CNC Carbide Boring Tool Stainless St
This MIL 5A60 L22 reverse-hand small-bore threading tool adopts solid tungsten carbide with premium high-silicon hard coating. Its 60° thread angle and 5mm rigid shank with reverse-cut design suit reverse internal threading of HRC40 steel and stainless steel on Swiss-type CNC lathes.
Precision-polished 60° thread cutting edges guarantee standard tooth profile and smooth chip removal in narrow inner-hole spaces. The wear-resistant high-silicon coating effectively reduces built-up edge, keeping stable thread accuracy and fine surface finish in long-term continuous machining.
Its compact reverse tool shank perfectly adapts to limited micro-bore working space. It prolongs tool service life, cuts tool-change downtime, and notably boosts overall efficiency for mass production of miniature reverse-threaded precision parts.
