Punta elicoidale KWB 205080 1 pz. rotazione destra

The KWB 205080 twist drill bit is a precision-ground, right-hand rotation drill made to DIN 338 standards. It features a Type N geometry with a 135° tip angle and cross-ground cutting edges to DIN 1412 C, providing self-centering performance for accurate starts. The bit has a cylindrical shank, industrial quality finish (self colour), and is supplied as a single piece for general drilling tasks in a range of materials.

Advantages

This drill bit offers precise, repeatable drilling thanks to its precision-ground flutes and cross-ground tip. The 135° tip angle reduces walking and improves centering on flat surfaces, while the Type N geometry and cylindrical shank ensure compatibility with standard chucks and holders. Manufactured to DIN standards, it provides consistent quality suitable for workshop and industrial use.

How to use

Secure the cylindrical shank in a compatible chuck or holder and set the drill press or handheld drill to right-hand rotation. Use appropriate cutting speeds and feed rates for the material being drilled; start at a lower speed for harder materials to avoid overheating. Apply steady, even pressure and clear chips frequently to maintain cutting performance and prevent clogging.

Recommendations

Use suitable cutting fluid for metal drilling to extend tool life when working with steel and alloyed steel. For small-diameter holes or delicate work, consider a pilot hole and gradual step-drilling to improve accuracy and reduce stress on the bit.
