MIL 3A60 L15 Anti-60° KEUE CNC Carbide Boring Tool Stainless St
This MIL 3A60 L15 reverse-hand small-bore internal threading tool adopts solid tungsten carbide with premium high-silicon hard coating. Its 60° thread angle and 3mm rigid compact shank deliver excellent rigidity for reverse threading of HRC40 steel and stainless steel on Swiss-type CNC lathes.
Precision-polished 60° thread cutting edges guarantee accurate standard tooth profile and smooth chip removal in narrow confined inner-hole spaces. The wear-resistant high-silicon coating effectively suppresses built-up edge, maintaining stable pitch precision and fine surface finish during long continuous production runs.
Its compact reverse-cut tool body perfectly adapts to limited micro-bore working space with 15mm effective machining depth. It prolongs tool service life, cuts tool-change downtime, lowers production costs and greatly boosts overall efficiency for mass production of miniature reverse-threaded parts.
