GRAFF solid-carbide drill bit (monolithic) 10,5 mm K10 with cylindrical shank is used for machining almost all steel grades (including high-strength and stainless steel. It’s ideal for hardened and spring steels, titanium alloys, cast iron, bronze, brass, copper and other hard-to-machine materials.
Drill bits are made of solid K10 carbide and have a high assurance coefficient.
Maximum strength of processed material is 1200 N/mm2.
Due to its short length, the carbide drill bit can be used at high RPM.
This series is analogues to DIN 6539 to the European classification.
