Kierrep pora KWB 206568

Twist drill bit KWB 206568 is a precision-ground DIN 338 twist drill with right-hand cut, type N, supplied in natural (self) colour. The drill has a 135° tip angle and is cross-ground to DIN 1412 C for self-centering performance. It features a cylindrical shank and industrial quality suitable for drilling steel, alloyed steel, cast steel, die castings, sintered steel, non‑ferrous metals and hard plastics.

Advantages

The KWB 206568 offers precise, self-centering drilling thanks to its cross-ground geometry and 135° tip angle. Precision ground flutes improve hole quality and cutting consistency, while industrial-grade heat treatment increases wear resistance and service life. The cylindrical shank ensures compatibility with standard chucks and drill holders.

Key specifications

How to use

Secure the drill bit in a compatible chuck or drill holder with the cylindrical shank fully inserted. Select appropriate cutting speed and feed for the workpiece material; use lower speeds for harder materials and higher speeds for non‑ferrous metals and plastics. Apply steady pressure and allow the drill to cut without excessive force. For deep holes, periodically withdraw the drill to clear chips and reduce heat buildup.

Recommendations

For best results and extended tool life, use cutting fluid when drilling steels and alloyed materials, ensure correct speeds and feeds for the material, and keep the drill bit clean of chips. Inspect for wear or chipping before reuse.
