Product information
Cobalt step drill for metal, steel, stainless steel, acrylic glass
and non-ferrous metals
Range: 6-38mm
Diameters: 6 - 9 - 13 - 16 - 19 - 21 - 23 - 26 - 29 - 32 - 35 - 38 mm
Number of cutting edges: 2
Shank diameter: 10 mm, with three faces against rotation in the chuck
Total length(incl. shank): 100mm
Max. thickness of drilled material: 4,5mm
Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC)
Coating: BLUE-DUR, increases the life of the drill when drilling with very limited cooling(spray, paste), as well as for dry cutting
Cutting conditions - steel: 1100 to 180 rpm
Cutting conditions - stainless steel: 550 to 100 rpm
Smaller diameters can be drilled at higher speeds, as the drilling diameter increases, the cutting speed and speed need to be reduced. 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.
