Vrták KWB 209660 — špirálový vrták, pravotočivý, 1 ks

kwb 209660 twist drill bit for right-hand rotation. Manufactured to DIN 338 standards with a type N geometry and roll-forged shank, this single drill is steam-hardened and finished in a blue-black colour. The tip has a 118° point angle and is designed for drilling alloyed and mild steel, castings, non-ferrous metals and hard plastics.

Advantages

The DIN 338 specification and roll-forged construction provide consistent concentricity and strength for general-purpose drilling. Steam hardening increases wear resistance while the 118° tip angle ensures good centring and chip formation across a range of materials. The blue-black finish offers surface protection and visual identification.

How to use

Secure the drill bit in a compatible chuck rated for twist drills, set the drill for right-hand rotation, and select an appropriate speed and feed for the material being drilled. Use cutting fluid when machining steels and castings to improve tool life and chip evacuation. Apply steady pressure without excessive force to avoid breakage; withdraw periodically to clear chips when drilling deep holes.

Recommendations

For best results, match rotational speed and feed to the material (lower speeds for harder steels, higher for non-ferrous metals and plastics) and use suitable lubrication when drilling ferrous materials.
