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
- Centring, drilling, core drilling and deburring of sheet metal, pipes and profiles in a single step, when using both hand drills and stationary equipment.
- The latest generation, multi-performance, stepped drill bits are ideal for processing sheet metal, plates, profiles and pipes made of conventional non-alloyed steel up to 1300 N/mm2 in strength, aluminium, cast iron, brass, bronze, wood and plastics with a thickness of up to 4.0 mm. Alloyed steels with strengths of up to 1300 N/mm2 can be processed up to a thickness of 2.0 mm.
- Cooling not absolutely necessary, but significantly increases service life
- Make sure that the feed is even
- Observe the speed table
- Do not push during core drilling — the stepped drill bit will automatically retract into the sheet metal
