KEUE CNC MKR 4R0.75 L10 High-Precision Carbide Groove Cutter Set-MKR Series for Boring & Milling Tools
This MKR 4R0.75 L10 small‑diameter internal grooving tool adopts solid tungsten carbide substrate with high‑hardness coating. It supports inner groove machining for holes above 4 mm, both forward and reverse cutting styles are available, well‑matched for Swiss‑type lathe small‑part turning operations.
Precision‑formed circular arc cutting edge delivers smooth arc‑shaped inner groove profiles. Optimized cutter geometry ensures stable chip breaking and smooth chip evacuation inside narrow inner holes. It effectively reduces tool chipping risk and maintains consistent dimensional accuracy during continuous grooving processes.
Rich‑size options cover various inner‑groove processing demands for steel and stainless‑steel workpieces. Compact rigid tool body fits narrow internal working space. It helps lower defective rate, extend tool service life, cut down tool‑replacement time and boost mass‑production efficiency of miniature components.
