Precise circular holes
No tool changes and shorter machining times
- Eliminates predrilling with smaller twist drill bits, precise tap without the bit running-out of centre
- Saves extra deburring, as the next larger step diameter performs this function
- Combines numerous bore diameters in a single tool
- Very fast tap and faster drilling process due to four high-performance blades and SMART STEP technology
Flexible, “smart” use
- Now also suitable for 10 mm strong material thickness (compared to conventional step drill bits, which are limited to 4 mm material thickness on sheet metal)
- For use in cordless drills as well as on hand-held, pillar, and upright drills.
- Compared to using core drill bits with magnetic core drills, there are no problems with hard-to-reach places (e.g. on T-beams) or problems due to insufficient adhesive forces
Very comfortable drilling
- Drilling with less strain
- Completely smooth running without getting caught in the workpiece
- No sheet metal distortion
- Simple re-drilling or enlarging of an existing drill hole
- Reduced force exerted on the tool during the drilling process
AlCrN multi-layer wear protection coating
- Extremely high temperature resistance of up to 1050° C
- Very high coating hardness of 3000 HV
- Multilayer construction for optimum chip removal and improved cutting properties (prevents material wear)
3-face shank
Prevents turning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage
ORSY® system compatible, compact and practical system cassette with useful details, such as stackability, optimised joint, and easy opening
- Ensure that there is sufficient cooling/lubrication
- Make sure that the feed is even
- Observe the rotation speed table
- Do not push during core drilling – the stepped drill bit will automatically retract into the sheet metal
- Pay attention to the total length of the stepped drill bit during drilling
