Drill bit set KWB 423140

The KWB 423140 drill bit set contains six roll-forged, steam-hardened drill bits with a right-hand cut and a 118° tip angle. Finished in blue-black colour, these type N bits are suitable for drilling alloyed and mild steel, castings, non-ferrous metals and hard plastics. The set is supplied in a hanging box for convenient storage and transport.

Advantages

Roll-forged construction and steam hardening provide increased toughness and wear resistance. The 118° tip angle and type N geometry offer reliable centring and efficient chip removal. The blue-black finish reduces glare and helps protect the flute surface. Right-hand cut ensures standard rotation compatibility with most drills.

Suitable for

• Alloyed steel
• Mild steel
• Castings
• Non-ferrous metals (e.g., aluminium, copper)
• Hard plastics

How to use

Secure the appropriate drill bit in the drill chuck, set the drill to the correct speed for the material, and apply steady pressure while drilling. Use cutting fluid or lubricant when working with steel or alloyed materials to extend bit life and improve chip evacuation. Withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

For best results, match drill speed and feed rate to the specific material and use appropriate cooling or lubrication for metalworking. Inspect bits for wear or damage before use and replace when cutting performance deteriorates.
