KEUE CNC Tungsten Steel Coated Groove Cutter Shaft MGR 3B0.5 L10 H0.6 0.5mm Effective Cutting Depth 3-Year Warranty ODM
This MGR 3B0.5 L10 H0.6 small‑bore internal grooving tool adopts integral solid tungsten carbide shank with high‑performance coating. The slim 3‑mm shank maintains decent rigidity, suppresses cutting chatter, and delivers stable grooving performance for ultra‑tiny inner hole machining tasks.
Precision‑ground grooving geometry ensures smooth chip evacuation in highly restricted inner‑hole space. The heat‑resistant hard coating effectively reduces built‑up edge, producing neat groove profiles, fine surface finish and reliable dimensional consistency for steel and stainless‑steel workpieces.
Optimized for miniature internal grooving and light parting operations, it fits Swiss‑type CNC lathes perfectly. Its slim profile adapts to minimal bore clearance, extends tool service life, lowers tool‑changing downtime and raises output for mass‑produced micro precision components.
