Spirálfúró KWB 209700 1 darab jobbmenetes

The KWB 209700 twist drill bit is a right-hand rotation, type N drill designed for general-purpose drilling in a variety of materials. It is roll forged, steam hardened, and finished in a blue-black colour. The drill has a 118° tip angle and is suitable for drilling into alloyed and mild steel, castings, non-ferrous metals and hard plastics.

Advantages

Roll-forged construction and steam hardening provide enhanced strength and wear resistance while preserving precise geometry. The 118° tip angle offers good centring and controlled cutting for common metal and plastic applications. Blue-black surface finish gives moderate corrosion resistance and a professional appearance. Single-piece design ensures rigidity and consistent concentricity during drilling.

How to use

Mark the drilling location and secure the workpiece to prevent movement. Select an appropriate drill speed and feed for the material being drilled; use lower speeds for hard or non-ferrous metals and higher speeds for softer materials. Use cutting lubricant when drilling steel or alloyed metals to extend tool life and improve chip evacuation. Apply steady, even pressure and withdraw the drill occasionally to clear chips. After use, clean the bit and store it dry to avoid corrosion.

Recommendations

For best results when drilling metal, start with a centre punch on the marked point to improve accuracy and reduce wandering. Use recommended cutting fluids for steel and periodically back the drill out to clear chips when drilling deep holes.
