This Bosch 12mm HSS-G drill bit is suitable for drilling alloyed and non-alloyed steel up to a tensile strength of 900 N/mm², cast steel, cast iron, malleable cast iron, sintered iron, non-ferrous metals and hard plastics.
This precision-ground drill bit enables up to 40% faster drilling and up to 50% lower feed pressure than a standard-ground HSS drill bit with a chisel edge.
It also features a self-centering split point tip, which means that you do not need to pre-punch or pilot drill up to 10mm in diameter.
