Description: The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics. The HSS Twist Drill Bit Ground is manufactured to DIN 338. The drill bit is Type N (flute angle) with a 135-degree tip and a diameter tolerance of h8. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers.

Review: Given up on cheap bits, wish I started buying these years ago. Use 2,3,4mm. Jobs much better and faster.

Review: I have quite a few Bosch drill-bits and generally they are o.k but these are absolutely terrible. Two snapped without much pressure and the rest just cannot go through anything thicker than a couple of mm. I have some old Piranha ones which I had lost but have since found. They have been used countless times and work. These are not fit for purpose. For those giving 5* reviews. What are you using them on?? I don't like leaving poor reviews but these are worthy of no stars......
