Broca helicoidal KWB 209720 1 ud. Rotación a derechas

The KWB 209720 twist drill bit is a right-hand rotation, roll-forged tool with a type N geometry and a blue-black finish. Steam hardened and ground to a 118° tip angle, it is intended for drilling a range of materials including alloyed and mild steel, castings, non-ferrous metals and hard plastics. Supplied as a single piece, this drill bit is suitable for general-purpose metalworking and workshop tasks.

Advantages

Roll forging increases the strength and concentricity of the drill; steam hardening improves wear resistance while the blue-black surface finish offers corrosion protection. Type N geometry with a 118° point angle provides reliable centring and efficient chip evacuation across a variety of metals and hard plastics.

How to use

Secure the drill bit in an appropriate chuck, set the drill to right-hand rotation and select a suitable speed for the material being drilled. Use cutting fluid when working with steels and harder alloys to extend tool life and improve chip removal. Apply steady, even pressure and withdraw periodically to clear chips when drilling deep holes.

Recommendations

For best results, match drill speed and feed to the material: lower speeds for harder alloys and castings, higher speeds for non-ferrous metals and plastics. Keep the cutting area cool with adequate lubrication when drilling steels to maintain hardness and to prolong life of the KWB 209720 drill bit.
