The latest generation, multi-performance, stepped drill bits with TiAIN coating for maximum service life, significantly faster drilling with quiet processing as well as greatly reduced burr formation in the processing of almost all thin-walled materials such as conventional steel up to 1300 N/mm2 strength, stainless steel, aluminium, cast iron, brass, bronze, wood and plastics.
9 times longer service life and up to 50% higher cutting speed
compared to conventional uncoated stepped drill bits
Improved centring and up to 100% faster spot drilling
Exclusive Speed grinding
Acceleration of the overall drilling process
Significantly lower feed forces
Optimised cutting geometry
- Completely smooth running without getting caught in the workpiece
- No distortion of sheet metal
- Improved roundness of the hole
- Greatly reduced formation of burrs on the edges
Up to 80% reduction in force exerted on the tool during the drilling process
Optimised cutting profile with smoother transitions between the individual stages
3-face shank
- No twisting in the drill chuck: faster, more comfortable working
- Optimum transmission of forces
- Protection of the drill chuck from damage
- Little effort required to open and close the drill chuck
