Bosch HSS-G 4mm dia Drill Bits (10 pack)
These Bosch 4mm HSS-G drill bits (10 pack) are 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.
These precision-ground drill bits enable up to 40% faster drilling and up to 50% lower feed pressure than standard-ground HSS drill bits with a chisel edge.
They also feature a self-centering split point tip, which means that you do not need to pre-punch or pilot drill up to 10mm in diameter.
Safety note: always use cutting oil when working with these Bosch HSS drill bits.
