STep drills - the next GENERATION

Point cut: The improved point cut geometry facilitates easier centring whilst supporting faster drilling in the workpiece. The new point cut geometry dramatically reduces lateral forces. Helix angle: The helix angle optimisation leads to reduced axial feed forces, enabling the drilling cycle to be performed significantly faster in less time. 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. 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. 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. 3-edge shank: 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.
