Four-edged cobalt step drill for thick sheets - up to 10mm Suitable for metal, steel, stainless steel, acrylic glass and non-ferrous metals, sheets and beams Range: 6-12mm Diameters: 6 - 7 - 8 - 9 - 10 - 11 - 12 mm(no need to pre-drill or punch) Number of blades: 4 Shank diameter: 8mm, with three faces against rotation in the chuck Total length(vč. stopwatch): 105mm Max. drilled material thickness: 10mm Special geometry of 4 cutting edges reduces working time by up to 75%. Thanks to the tip, there is no need to punch or pre-drill the sheet. An excellent helper for hard-to-reach places, eg for drilling into T-beams. Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC) Coating: TITAN-TEC, increases the life of the drill when drilling with very limited cooling(spray, paste), as well as when dry cutting. We recommend using cutting oil. Smaller diameters can be drilled at higher speeds, with increasing drilling diameter it is necessary to reduce the cutting speed and speed. Failure to maintain the speed or overheating the drill may cause it to become dull. Transitions to a larger diameter also perfectly needle the drilled hole. Thanks to the spiral groove, the drilling is smooth, the chips do not stick, low cutting forces, the drilled material has fewer burrs and the tool has a longer endurance. Suitable for sheets with a thickness> 2mm.
