Spiralno svrdlo KWB 206585

Twist drill bit KWB 206585 is a precision-ground, right-hand twist drill manufactured to DIN 338 standards. The bit is type N with a 135° tip angle and cross-ground according to DIN 1412 C for self-centering performance. It is finished in its natural (self) colour and supplied as a single cylindrical piece suitable for industrial use.

Advantages

The drill bit offers precise self-centering thanks to the cross-ground tip and a 135° point that reduces walking on the workpiece. Precision grinding to DIN 338 and DIN 1412 C ensures consistent geometry and hole quality. Its cylindrical shank and single-piece construction provide robustness and straightforward mounting in standard chucks and holders.

Key specifications

How to use

Clamp the cylindrical shank securely in a compatible chuck or drill holder. Select appropriate spindle speed and feed for the work material—lower speeds for hard materials like alloyed steel and higher speeds for non-ferrous metals and plastics. Use steady pressure and allow the drill to clear chips frequently to maintain hole quality. For deep holes, withdraw regularly to remove chips and reduce heat buildup.

Recommendations

Use cutting fluid when drilling steel and alloyed steel to improve tool life and hole finish. For non-ferrous metals and plastics, a light lubricant or air cooling is usually sufficient. Inspect the drill for wear or damage before use and replace if the cutting edges are chipped or blunted.
