## Summary description

The KWB 421856 drill bit set includes 19 twist drill bits with sizes ranging from 1.0 to 10 mm. Designed for right-hand rotation, this set is ideal for various drilling tasks.

## Long description

Drill bit set KWB 421856 contains 19 titanium-nitrided HSS twist drills with sizes from 1.0 mm to 10 mm. The bits are right-hand cutting, precision ground with a 135° split-point tip and a cylindrical shank, finished in gold colour for reduced friction and extended tool life. Supplied in a metal case for organised storage and transport.
Advantages
The titanium nitride coating reduces wear and friction, increasing service life and cutting performance. Precision-ground flutes and a split-point (self-centring) tip improve drilling accuracy and reduce walking on the workpiece. The 135° tip angle is suitable for a wide range of materials, while the high-quality surface finish helps chip evacuation and resists heat and corrosion.
Suitable for
Alloy and non-alloy steel
Cast steel and malleable cast iron
Sintered iron and non-ferrous metals (copper, bronze, nickel silver)
Hard plastics and general workshop drilling tasks

How to use
Select the appropriate drill size for the hole required and secure the workpiece. Fit the cylindrical shank into a compatible chuck and tighten securely. Use suitable cutting speed and feed for the material being drilled, applying steady pressure and allowing chips to clear. For best results, especially in harder materials, use cooling or lubricant as appropriate and avoid excessive heat build-up.
Usage recommendations
Use lower speeds for harder materials and higher speeds for softer metals and plastics; apply cutting fluid when drilling steels to extend tool life. Replace worn bits to maintain accuracy and safety.
