Cobalt Drill Bits (HSS-Co)

Cobalt drills are a preferred drill for harder materials especially stainless steel. The primary reason for this being they hold there rigidity and hardness at a higher temperature than HSS drill bits. All our cobalt drills are under QUNXING brand and as such have split points (self centering points). Cobalt drills are more suited to CNC machines, Pillar Drills and Drill Presses due to the brittleness of the material compared to standard HSS

Cobalt Drills are primarily for drilling in the following materials (Please see the coated variants for use on harder materials):

Alloyed and Non alloyed Steel up to 1000N/mm2Soft and Hard Stainless SteelSoft Cast IronAluminiumCopperBrass and BronzePlastics
