KEUE CNC High-Precision 0.001in Carbide 2-Flute Arc Groove Milling Cutter-4mm Diameter 0.5L/min Coolant Various Sizes Available
This MKR series small-bore internal arc grooving tool is forged from solid tungsten carbide with HRC92.6 substrate hardness. Available in both right-hand (MKR) and left-hand (MKL) versions, it fits bores above 4mm, delivering exceptional rigidity for precision grooving on Swiss-type CNC lathes.
Precision-ground arc cutting edges ensure highly consistent groove profiles and smooth chip evacuation in confined inner-hole spaces. The premium wear-resistant coating effectively suppresses built-up edge, guaranteeing excellent surface finish and stable dimensional accuracy for steel and stainless steel workpieces.
Offered in a full range of specifications with varied radii and lengths, it adapts to diverse internal grooving needs. Its compact rigid shank fits narrow machining spaces perfectly, prolongs tool life, cuts changeover downtime and significantly boosts mass production efficiency of miniature parts.
