## Long description

Drill Bit KWB 421105 5mm is a precision-ground HSS twist drill with a 5 mm diameter and a 1/4" hexagon shank to ISO 1173 (E 6.3). It has a 135° tip angle, right-hand cut type N and a natural (self) finish. The bit is supplied in a blister pack and is compatible with cordless drivers, drills and bit holders featuring a 1/4" hexagon drive to ISO 1173.
Advantages
The KWB 421105 combines a precision-ground flute geometry and high-speed steel material for accurate hole making and extended wear resistance. The 1/4" hexagon shank allows quick tool changes in chucks and bit holders, while the 135° tip angle improves centring and reduces walking on a range of materials. The single-bit blister pack keeps the tool protected and easy to store.
Suitable for
Alloyed and mild steel
Cast steel and cast iron
Sintered steel
Non-ferrous metals (e.g., aluminium, brass)
Hard plastics

How to use
Mount the 1/4" hex shank securely in a compatible cordless driver, drill or bit holder with ISO 1173 hex drive. Use appropriate drill speed and feed for the chosen material and apply steady pressure; for metals, begin with lower speed and increase as appropriate. Use cutting fluid when drilling steels and cast materials to extend tool life and improve chip evacuation. Retract occasionally to clear chips when drilling deep holes.
Usage recommendations
For best results on hard or alloyed steels, use a cutting lubricant and moderate speed. When drilling non-ferrous metals and plastics, higher speeds and reduced feed can improve finish; avoid excessive heat build-up to prevent material melting or tool wear. Regularly inspect the tip for wear and replace the bit when accuracy or cutting performance declines.
