KEUE CNC MKR 4R0.4 L10 High-Precision Carbide Arc Groove Milling Cutter-4mm Diameter 1 Year Warranty Various Sizes Available
This MKR 4R0.4 L15 small‑diameter internal groove cutter adopts high‑quality solid tungsten carbide substrate. It supports both forward and reverse cutting for inner groove machining, suitable for inner holes above 4mm. The rigid tool body delivers stable performance for Swiss‑type lathe small‑part processing tasks.
Precision‑ground arc‑shaped cutting edge forms smooth arc grooves with high dimensional consistency. Optimized chip‑breaking geometry ensures smooth chip evacuation inside narrow inner holes. It effectively resists wear, reduces burrs and guarantees fine surface finish for steel and stainless‑steel workpieces.
Multiple sizes of MKR series are in stock to meet various inner‑groove processing demands. Compact tool profile fits narrow inner‑hole space well. It lowers scrapping rate, extends tool service life, cuts downtime for tool replacement and improves overall efficiency of miniature component mass production.
