RUKO SPB-DIN338-HSS-G spiraalboor 10,5 mm kruisslijping

Precision-ground HSS twist drill bit with a 10.5 mm diameter and 135° split point for self-centering accuracy. Complies with DIN 338, ideal for alloyed and unalloyed steel up to 900 N/mm², cast iron, non-ferrous metals, plastics, and wood.

Overview

The RUKO SPB-DIN338-HSS-G is a high-performance twist drill bit manufactured from high-speed steel (HSS) with a ground finish (HSS-G). Its split point geometry (Kreuzanschliff) eliminates walking and reduces thrust, enabling precise hole positioning without center punching. The bright finish provides clean cutting edges and efficient chip evacuation.

What stands out

• DIN 338 standard dimensions ensure compatibility with standard drill chucks and collets.
• Versatile across steel, cast iron, non-ferrous metals, plastics, and wood.
• Cylindrical shank with h8 tolerance for secure clamping in keyless or keyed chucks.
