High-quality steel drill bits with exact dimensional accuracy for precise drilling

The greenteQ twist drills HSS-G DIN338 are made of high-quality HSS (High Speed Steel) and ground from solid material, which results in high breakage resistance and good chip removal. The specially ground flank face (cross cut) reduces drilling resistance. This enables fast and durable drilling. The main areas of application are drilling in steel, various types of cast iron, graphite, bronze, brass, aluminum and plastics.
