KEUE CNC Nano Blue Coated 1.5*D4*50*60 High-hardness Spot Drill Double-edge Chamfering Cutter for Nonferrous Metals 3-year
These 2-flute solid carbide spot drills feature advanced nano-blue high-hardness coating, with 1.5mm cutting diameter, 4mm shank, 50mm overall length and 60° point angle. Designed for HRC60 hardened steel and stainless steel, they handle centering, spotting and chamfering on CNC machining equipment.
The specialized nano-blue coating provides exceptional wear resistance and thermal stability for high-hardness material machining. Precision-ground sharp cutting edges ensure precise centering, burr-free smooth chamfers and stable dimensional accuracy in continuous high-speed processing.
Ideal for pre-drilling centering, spot facing and edge chamfering of metal workpieces, they integrate multiple functions to reduce tool changeovers. They boast prolonged service life, lower comprehensive tooling costs and effectively improve overall machining efficiency.
