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.
Bosch offer a standard 1 year warranty with all of their machines, batteries and chargers. You can extend this to a 3 year warranty for power tools or a 2 year warranty for batteries and chargers by registering your product on the Bosch Pro 360 portal here within 4 weeks of purchase.
Note: Due to the nature of their application, accessories and consumables do not have a wear and tear guarantee or warranty. If you are unhappy with your product then you can contact Bosch directly to discuss this.
