Product description

  • Better Hss Drill Bit Set Metal drills are made from a high-speed steel alloy (HSS4241), hardened at high temperatures, with excellent toughness and thermoplasticity. It is hard and wear-resistant and cuts faster than ordinary high carbon steel drill bits. Roll forged and manufactured to DIN338 standard.
  • Professional Drill Bit Tip precision 135 self-centring design prevents twist drill bit slippage for efficient drilling and faster removal of chips and particles. The straight shank design snaps easily into standard drills, providing a solid fit for precise drilling operations.
  • Sharp Drill Bit Edge Precision ground cobalt drill bit for fast drilling results with low contact force without pre-punching or pre-drilling. For everyday DIY jobs, drill quickly and accurately in soft metals eg. mild steel, copper, aluminium, iron, plastic, wood, plasterboard.
  • Long-life Oxide Coating The drill has a black oxide coating on the surface, which increases the surface hardness and lubricates the drill, improves wear resistance and sharpness by reducing friction and adhesion. And extends the life of the drill by approximately 50%.
  • Twist Drill Bits Sizes Cutting edge diameter 2.5mm 0.098"; round shank diameter 2.5mm 0.098"; cutting edge length 30mm 1.18"; overall length 57mm 2.24". Used with hand drills, drill presses, bench drills, machining centers, CNC lathes, etc.
