Product information

Description

Twist Drill Bit Bosch HSS Twist Drill Bit Cobalt 4.1mm is a high-speed steel drill with cobalt content, designed for precise and durable metal drilling. Manufactured to DIN 338 as a Type N twist drill with a 135° split-point tip and diameter tolerance h8, it features a cylindrical shank equal to the drill diameter and is suitable for use in drill stands and drill drivers.

Advantages

The cobalt-enhanced HSS construction improves heat resistance and tool life when drilling stainless and alloyed steels. The two-cutters and two-flute geometry evacuate chips quickly to reduce wear, while the pointed split-point tip provides active cutting and accurate centring without wandering.

Suitable for

  • Alloyed and non-alloyed steel
  • Stainless steel
  • Cast iron and cast steel
  • Acid- and heat-resistant steels

How to use

Secure the Bosch HSS Twist Drill Bit Cobalt in a drill driver or drill stand with a suitable chuck. Mark and centre the drilling position, start at low speed to establish the hole, then increase speed as appropriate for the material being drilled. Use steady pressure and allow the bit to evacuate chips through the flutes. Apply cutting fluid when drilling stainless or heat-resistant steels to reduce heat build-up and extend bit life.

Usage recommendations

For best results when drilling stainless and heat-resistant steels, use cutting fluid, maintain appropriate drill speed for the material, and periodically clear chips from the flutes. Do not force the bit; let the split-point tip guide and cut at a steady rate.
