Cobalt step drill for metal, steel, stainless steel, acrylic glass and non-ferrous metals - for cable connections Range: 7-32,5mm Diameters: 7 - 10,5 - 12,5 - 14,5 - 16,5 - 18,5 - 20,5 - 23,5 - 25,5 - 30,5 - 32,5 mm Number of edges: 2 Shank diameter: 12mm, with three flats against rotation in the chuck Total length(incl. shank): 100mm Max. drilled material thickness: 3mm / 6mm Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC) Coating: BLUE-DUR, increases drill life when drilling with very limited cooling(spray, paste), as well as for dry cutting Cutting conditions - steel: 1000 to 250 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.

Cutter - core drill bit, set of six top drills and four centering pins Karnasch SILVER-LINE 25 in practical case Set includes drills: 12 , 14, 16, 18, 20, 22 mm Set of centering pins: 6,34 x 77 mm (2pcs) Recommended drilling depth - max. - HSS-XE - Special High Alloy Steel Hardness of Teeth: 68HRC Cat. No.: 38720.1474 These core drills are made of special HSS-XE high-alloy steel, extreme hardness on tooth tips (up to 68 HRC), high wear resistance and long durability. Only a few manufacturers are able to produce HSS hardened core drills in several stages. hard tooth tips (68 HRC) and flexible and durable drill body. HSS-XE / ASP j core drills For different diameters and drilling depths, five different geometry of the drill are applied, so that the result of the work is always perfect.
