Drills made of high-speed steel (M35), hardness 66 ° HRC (+/- 1 °), point angle 135 °, cut with chamfer correction, giving self-centering properties without the need for punching or drilling. ground, highly flexible and torsionally resistant, maximally protected against breakage.

Diameter tolerance h8.

Cylindrical handles corresponding to the diameter of the drill bits. Drill bits enable 40% faster drilling progress and 50% reduction of feed force. Cutting material structure reinforced with 5% cobalt (Co) alloy ensures low coefficient of friction, reduces the risk of chips sticking to the drill bits and increases drilling efficiency.

The chemical-thermal process of hardening and precise 2-cut sharpening reduce the wear of drills and increase the resistance to internal stresses occurring during operation. Designed for industrial applications, for machining alloy and carbon steels with a strength up to 900 N / mm², stainless steel, acid and heat-resistant, gray cast iron, cast steel, titanium and its alloys. Compliant with DIN-1412.

Drill bits recommended for stationary use, using a drill stand, column drills, lathe chucks or milling heads.
