Product information
Cobalt step drill for metal, steel, stainless steel, acrylic glass
and non-ferrous metals
Range: 6-30mm
Diameters: 6 - 8 - 10 - 12 - 14 - 16 - 18 - 20 - 22 - 24 - 26 - 28 - 30 -(32needing diameter) mm
Number of edges: 2
Shank diameter: 10mm, with three faces against rotation in the chuck
Total length(incl. shank): 98mm
Max. drilled material thickness: 4mm
Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC)
Coating: uncoated
Cutting conditions - steel: 1100 to 260 rpm
Cutting conditions - stainless steel: 550 to 120 rpm
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.
