Twist Bits - Set of 19

This set of 19 twist drill bits can be used in a drill press or electric hand drill and are designed to be used on alloyed and non alloyed steel, non ferrous metal, cast iron and hard plastics. The bits have been fully ground to give precise concentricity to ensure a highly accurate hole. They have a split point and 135° drill point angle which gives the bit good centering properties meaning the bit will not wander as you start to drill. The split point and optimum drill point angle also mean little pressure is required to cut very quickly through your stock. The deep flutes allow fast chip clearance, even when drilling through thicker stock.

The drill bits are made from M2 high speed steel which is extremely hard wearing and retains hardness over prolonged use, even when heated. The material is perfect for metal drilling applications where the drill bit will naturally heat during use, the heat generated will not deform the bit and it will always keep the same cutting geometry over its lifetime. The drill bits are hardened to ensure they are highly resistant to deformation and tempered to reduce brittleness and increase ductility and toughness.

The twist bits are certified to ensure the dimensional accuracy of the hole. The set contains 19 drill bits from 1mm to 10mm in 0.5mm increments and the bits were chosen due to their superior cutting performance and durability. The bits have a high anti torsion capability and a low danger of fracture. ©
