The KWB 206630 twist drill bit is a precision-ground, right-hand rotation drill bit manufactured to DIN 338 standards. It features a type N profile with a 135° tip angle and cross-ground geometry to DIN 1412 C, providing self-centering performance and industrial-quality durability. The bit is supplied in natural (self) colour and is suitable for drilling in a range of materials including steel, alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics.

Advantages

This drill bit offers a precisely ground cutting geometry for accurate holes and reliable self-centering thanks to the cross-ground tip. The 135° tip angle reduces walking on hard surfaces and improves centring in tough materials. Manufactured to DIN 338 and DIN 1412 C specifications, the bit provides consistent industrial quality for professional and DIY applications.

How to use

Secure the KWB 206630 twist drill bit in a compatible drill chuck, ensuring correct concentric clamping. Select an appropriate drilling speed and feed rate for the material being drilled. Use steady pressure and allow the bit to cut without excessive force; withdraw periodically to clear chips when working in deep holes or soft materials. For harder materials, use cutting fluid or coolant to extend tool life and improve hole quality.

Recommendations

Match drill speed and coolant use to the workpiece material: higher speeds for non-ferrous metals and plastics, reduced speeds with coolant for alloyed and cast steels. Inspect the bit for wear before use and replace when cutting edges become dull to maintain hole accuracy and safety.
