Steel HSS drills, Ø 1.2 mm, 3 pieces Proxxon

Set of 3 drills in wolfram-vanadium steel, diameter 1.2 mm, Proxxon.

Steel HSS drills of selected quality. Solid and rigid construction. Axis and helical part forged in one piece. Optimal concentricity. Good hardness ensures longevity and elasticity. For metal work, non-ferrous metal, plastic, turntables, hard and soft wood. Speed: soft materials approx. 8,000 rpm., hard materials approx. 3,000 rpm. Priority Ø 2.35. All dimensions are in mm.

remark: The term HSS tool for this group comes from the drilling equipment used. High-speed steel (high-speed steel = HSS) is a high-alloy steel, which is wear-resistant and up to about 600°C resistant to deformation by its manufacturing process. It is advisable to use a cutting oil or cooling emulsion during the machining of steel. White spirit or petrol is used during aluminum machining. Plastic and wood can be worked generally dry.
