Precision Tungsten Carbide MQL 4R0.1 L15 Internal Turning Tool Small Bore Counterbore Cutters for Stainless Steel Boring Tools
This MQL 4R0.1 L15 reverse small‑bore turning tool adopts solid tungsten carbide substrate with premium high‑silicon nano coating. Its reverse‑cutting structure and 4mm shank are tailored for back boring and profiling of HRC40 steel and stainless steel on Swiss‑type CNC lathes.
Precision‑polished R0.1 cutting edges deliver stable cutting performance and smooth chip removal in confined inner bores. The wear‑resistant high‑silicon coating effectively reduces built‑up edge, ensuring consistent dimensional accuracy and excellent surface finish for continuous machining.
Its compact reverse tool body perfectly adapts to narrow micro‑hole machining spaces. With a full range of specifications, it extends tool life, cuts tool‑change downtime, and greatly boosts overall productivity for mass production of miniature precision parts.
