- Up to 4X 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
- The helix angle optimization 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 centering whilst supporting faster drilling in the workpiece
- The new point cut geometry dramatically reduces lateral forces
- The three-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
- The optimized 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 optimized 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 optimized cutting and service life is achieved through the step drills special wedge angle
- The smooth drilling operation of the step drill means there is no 'warping' when drilling thinner materials
