Cobalt Drill Bits (HSS-Co)


Cobalt Drill Bits (HSS-Co) - From £1.07 Each Online

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 the Phantom brand and as such have split points (self centring 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

Phantom: A range of HSS-Co drills bits that offer benchmark quality, precision ground drill bits that maintain precise diameters, thus leaving precision tolerances in drilled holes. Not only are Phantom HSS-Co drills precise, they also last longer under production conditions, excavate swarf quicker and feature a ‘split point’ or ‘self centring’ tip.
