HSS drill bits made from selected grade steel . Solid and rigid construction. Shank and helical section forged from a single piece. Optimal concentricity. High hardness ensures durability and elasticity. For working with metal, non-ferrous metals, plastics, base plates, and hard and soft woods. Speed: soft materials approx. 8,000 rpm, hard materials approx. 3,000 rpm. Shank diameter 2.35 mm. All dimensions are in mm.

Note: The term HSS tool for this group comes from the drilling equipment used. High-speed steel (HSS) is a highly alloyed steel that is wear-resistant and, due to its manufacturing process, resists deformation up to approximately 600°C. It is advisable to use a cutting oil or cooling emulsion when machining steel. White spirit or petroleum is used when machining aluminum. Plastic and wood can generally be machined dry.
