Cemented Carbide Drill Bit Tungsten Steel Internal Cooling 3 Times Diameter SFP203N-0500-06-01R
This SFP203N-0500-06-01R solid carbide drill features a 3×D length-to-diameter ratio with internal coolant design, engineered as a compatible replacement for Sandvik-standard drilling tools. Forged from premium tungsten steel with ultra-fine grain substrate, it delivers reliable performance across both stable and unstable cutting conditions.
Its curved cutting edge reduces cutting force significantly, while the optimized chisel edge ensures excellent centering accuracy without pre-drilling. The refined flute geometry guarantees smooth chip evacuation, and the nano-composite PVD coating extends tool life with outstanding wear and heat resistance.
It achieves H8–H9 hole tolerance and fine inner wall finish on steel, cast iron and alloy workpieces. Compatible with standard CNC machining centers, it offers stable batch consistency at competitive cost, ideal for general machinery, mold and automotive manufacturing.
