Step drillS the next generation SMooth run. preciSe cut. long life. + up to 4 times longer service life + improved centring with quicker hole drilling + extremely smooth run eliminates 'grabbing' material + Significantly reduced cutting forces + highly efficient chip removal, reduces heat build up + reduced 'feathering' in the hole + Drilling productivity significantly increased + optimal performance in all drilling machines including hand-held drills helix angle point cut the helix angle optimisation leads to reduced axial feed forces, enabling the drilling cycle to be performed significantly faster in less time. the improved point cut geometry facilitates easier centring whilst supporting faster drilling in the workpiece. the new point cut geometry dramatically reduces lateral forces. improved centring / drilling Very smooth run considerably reduced feathering 3-edge Shank cutting edgeS the optimised cutting geometry enables very smooth operating performance. hole roundness and surface finish quality of the hole is significantly improved, avoiding any feathering on the edges. chip Space geoMetry the optimised chip geometry ensures ideal chip and heat removal. the service life of the step drill is substantially improved thanks to the significant reduction in heat development. the ideal balance between optimised cutting and service life is achieved through the step drills special wedge angle. the specially modified cutting geometries facilitates an extremely smooth transition between each of the steps. radial forces are dramatically reduced by up to 80% when drilling. every step on the tool is designed with a special optimised relief, clearance angle, which prevents the edge from breaking out and from catching in the workpiece. the smooth drilling operation of the step drill means there is no 'warping' when drilling thinner materials. reductions in torque forces from the step drill, protect the drilling machine from overload and enable an 'easy to use' hole making solution. the 3-edge shank provides a secure hold within the chuck, eliminating any possibility of slippage. this provides the maximum force transfer to the cutting edges of the tool. ideal for use in hand-held drilling machines. Ø2 C HSSE Co 5 HSS Ø1 118° 90° Step drills HSS and HSSE-Co 5, CBN ground, spiral fluted with split point L1 The CBN ground and spiral flutes guarantee quiet running and high cutting performance. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. The cone makes it easier to withdraw the tool from the material. available July 2018 Ø3 Packing unit: in plastic tubes of 1 - Cooling - Adjust speed - Do not press - Step drill is pulled automatically into the plate Steel (N/mm2) < 900 Brass Steel (N/mm2) < 1100 Bronze Steel (N/mm2) < 1300 Plastics Rust-resistant steel Cast iron Aluminium Titanium alloyed Size no.
