Product Selling Points

The MIR 4A60 L15 R0.12 small‑bore internal threading tool adopts solid tungsten carbide substrate with premium black‑high coating. Equipped with 4mm rigid shank, 60‑degree thread angle and 15mm cutting depth, it suits Swiss‑type lathes for machining steel and stainless steel within HRC50.

Precision‑ground 60° threading edge with R0.12 nose radius delivers accurate thread profile inside tiny inner holes. Its black‑high coating effectively lowers cutting friction and avoids built‑up edge, keeping stable dimensional accuracy and excellent surface finish during continuous processing.

Its slim and compact shank perfectly fits the narrow inner‑hole space of miniature precision workpieces. Superior wear resistance extends tool service life, reduces tool‑change frequency, and improves mass‑production efficiency of micro‑threaded metal parts for turning workshops.
