Drill bit KWB 209650 — twist drill bit, right-hand rotation, 1 pc

kwb 209650 twist drill bit, roll-forged and steam-hardened with a blue-black finish, designed for right-hand rotation. The bit features a 118° tip angle and type N geometry (DIN 338), suitable for drilling alloyed and mild steels, castings, non-ferrous metals and hard plastics. Supplied as a single piece.

Advantages

The roll-forged shank offers dimensional accuracy and durability while steam hardening increases wear resistance. The blue-black surface treatment provides corrosion protection. The 118° tip and type N profile deliver stable centring and reliable chip formation across a range of materials. Compatibility with standard chucks and right-hand rotation makes the bit suitable for common drills.

Suitable for

• Alloyed and mild steel
• Castings
• Non-ferrous metals (e.g., aluminum, brass)

How to use

Secure the twist drill bit in the drill chuck and tighten firmly. Select an appropriate drill speed for the material being worked—lower speeds for steels and higher speeds for non-ferrous metals and plastics. Use cutting lubricant when drilling steels and castings to extend tool life and improve chip evacuation. Apply steady feed pressure and withdraw periodically for chip clearing when drilling deeper holes.

Usage recommendations

For best results when drilling steel and castings, use cutting oil and moderate speeds; for non-ferrous metals and hard plastics, use higher speeds and minimal lubrication. Match drill diameter and machine capability, and always follow safety practices including eye protection and secure workholding.
