Burghiu elicoidal KWB 238645

The KWB 238645 twist drill bit is a precision ground, right-hand, Type N drill designed for accurate and reliable drilling. Finished with a titanium nitride coating in a gold colour, it features a 135° tip angle and a cross-ground geometry to DIN 1412 C for self-centring performance. Supplied as a single piece in a blister pack, this cylindrical industrial-quality drill bit is suitable for demanding applications and offers reduced friction and extended tool life.

Advantages

Titanium nitrided surface treatment provides low friction and increased wear resistance. Precision grinding and cross-ground tip ensure clean holes and improved centring. The 135° tip angle and high-quality finish deliver consistent performance in various materials, while the single-piece design gives robustness for industrial and workshop use.

How to use

Secure the material and select an appropriate drill speed and coolant based on the workpiece material. Clamp the cylindrical shank in the drill chuck and start drilling with steady, even pressure. For best results in harder materials, use reduced speed and intermittent pecking to clear chips. Allow the drill to cool if it becomes hot to preserve the titanium nitride coating and maintain cutting performance.

Recommendations

Use appropriate personal protective equipment (eye protection, gloves) and follow machine safety guidelines. Match drill speed and feed to the material: lower speeds for hardened or tough alloys, moderate speeds for non-ferrous metals and plastics. Inspect the cutting edges regularly and replace the drill when wear affects hole quality.
