- Performs centering, drilling, core drilling and deburring in one step when using both hand drills and stationary equipment on sheet metal, pipes and profiles.
- Latest generation Multi Performance step drill bits are ideal for processing sheet metal, plates, profiles and pipes made of conventional unalloyed steel up to 4.0 mm thickness with strength up to 1300 N/mm2, as well as aluminum, cast iron, brass, bronze, wood and plastic materials. Alloyed steels with strength up to 1300 N/mm2 can be processed up to 2.0 mm thickness.
- Cooling is not mandatory but significantly extends service life
- Ensure that the feed rate is constant
- Follow the speed table
- Do not push during core drilling - the step drill bit is automatically pulled by the sheet metal
