KEUE CNC 3-Year Warranty Nano Blue Coated Spot Drills 2*D4*50*60 High-hardness Double-edge Chamfering Cutter Tungsten for
These 2-flute solid carbide spot drills adopt advanced nano-blue high-hardness coating, with 2mm cutting diameter, 4mm shank, 50mm total length and 60° point angle. Built for HRC60 hardened steel and stainless steel, they perform centering, spotting and chamfering on CNC equipment.
The specialized nano-blue coating delivers exceptional wear resistance and thermal stability for high-hardness machining. Precision-ground sharp edges ensure accurate centering, burr-free smooth chamfers and consistent dimensional accuracy in continuous high-speed operations.
Ideal for pre-drilling centering, spot facing and edge chamfering of metal workpieces, they integrate multiple functions to cut tool change frequency. They offer extended service life, lower tooling costs and effectively boost overall machining efficiency.
