1. Point cut
The improved point cut geometry facilitates easier centering whilst supporting faster drilling in the workpiece. The new point cut geometry dramatically reduces lateral forces.
step drill generation
Up to 4 times more holes
Smooth and quiet drilling
Significantly improved drilling result
The improved point cut geometry facilitates easier centering whilst supporting faster drilling in the workpiece. The new point cut geometry dramatically reduces lateral forces.
The helix angle optimisation leads to reduced axial feed forces, enabling the drilling cycle to be performed significantly faster in less time.
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 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.
Up to 4 times longer service life
Improved centering 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
