RUKO SPB-DIN338-HSS-G Twist Drill Bit 10.5 mm Split Point

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.
