MIR 4A60 L15 Carbide Alloy Right Hand Spiral Flute Internal Thread Boring Tool with High Coating for Small 5A55 Holes

Product Selling Points

This MIR 4A60 L15 internal threading insert adopts solid tungsten carbide with premium black‑high coating. It has a 4mm rigid shank, 60‑degree thread angle and 15‑mm cutting depth, designed for Swiss‑type lathes to process steel and stainless steel below HRC50 hardness.

Precision ground 60° threading edge supports 0.8‑1.5 pitch range for small‑diameter internal threads. Advanced black‑high coating reduces friction and suppresses built‑up edge, delivering stable thread profile and fine surface finish under continuous heavy‑load machining conditions.

Slender‑shank structure adapts well to narrow inner‑bore space of miniature precision parts. Excellent wear resistance extends tool service life, lowers tool‑replacement frequency, and improves overall productivity for mass‑production of micro‑threaded metal components.
