Precise, circular drilling
No tool changes and shorter machining times
- Saves pre-drilling with smaller twist drill bits, precise tapping without running off centre
- Saves extra deburring, as the next largest step diameter performs this function
- Combines numerous drill hole diameters in a single tool
- Very fast tapping and accelerated drilling progress due to four high-performance cutting edges and SMART STEP technology
Flexible, smart use
- Now also suitable for thicker workpieces with a material thickness of up to 10 mm (compared to conventional stepped drill bits, which are limited to sheet metal up to 4 mm thick)
- Specially designed version that combines all core hole dimensions (dia. 3.3-10.2 mm) for through hole threads M4-M12 to 1.5xD in a single tool
- For use in cordless screwdrivers and hand, box column and pillar drills.
- Compared to using annular cutters with magnetic core drills, there are no issues when accessing hard-to-reach places (e.g. on T-beams) or due to adhesive force being too low
Extremely comfortable drilling
- Effortless drilling
- Completely smooth running without getting caught in the workpiece
- No warping of sheet metal
- Simple boring 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 up to 1,050 °C
- Very high coating hardness of 3,000 HV
- Multi-layer structure for optimal chip removal and improved cutting properties (prevents material becoming welded)
3-flat shank
Prevents spinning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage
Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
- Ensure that there is sufficient cooling/lubrication
- 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
- Pay attention to the total length of the stepped drill bit during drilling
