Vrták do kovu KWB 205070 1 kus pravotočivý

The KWB 205070 twist drill bit is a precision-ground right-hand drill compliant with DIN 338. It features a 135° tip angle and is cross-ground according to DIN 1412 C for reliable self-centering. Finished in natural (self) colour, the cylindrical shank drill is made to industrial quality standards for use in a range of materials including steel and alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics.

Advantages

The drill bit offers accurate centring due to the cross-ground geometry and a wide 135° tip suitable for general-purpose drilling. Precision grinding ensures consistent performance and dimensional accuracy. Its industrial-quality manufacture provides durability for repeated use across different materials when paired with appropriate drilling speeds and cutting conditions.

Key specifications

How to use

Secure the drill bit in a compatible chuck with the correct clamping for a cylindrical shank. Select appropriate spindle speed and feed based on the material being drilled and use cutting lubricant when recommended (for steels and alloyed steels). Start drilling with steady pressure to allow the self-centering tip to engage, then maintain consistent feed until the hole is complete. Retract periodically for chip clearance when drilling deep holes.

Recommendations

Use suitable cutting speeds and lubricants for the material chosen; for ferrous materials apply cutting fluid, and for non-ferrous metals and plastics use higher speeds with light feed to prevent clogging and melting. Inspect the drill for wear and replace when cutting performance degrades.
