Highly precise circular holes
No tool changes and shorter machining times
- Eliminates predrilling with smaller twist drill bits, precise tapping without running-out of centre
- Saves extra deburring, as the next larger step diameter performs this function
- Combines numerous bore diameters in one tool
- Very fast spot drilling and faster drilling process thanks to four high-performance cutting edges and SMART STEP technology
Flexible, “smart” use
- For the first time, also suitable for up to 10 mm thick workpieces (in comparison, conventional stepped drill bits are limited to sheet thicknesses of 4 mm)
- Specially designed version that combines all core hole dimensions (Ø 3.3–10.2 mm) for through hole threads M4–M12 to 1.5xD in a single tool
- 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 in hard-to-reach places (e.g. on T-beams) or difficulties due to insufficient adhesive force
Extremely convenient drilling
- Low-effort drilling
- Completely smooth running without getting caught in the workpiece
- No distortion of sheet metal
- Easy to bore or enlarge an existing drill hole
- Less force exerted on the tool during drilling
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 spinning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage
Sustainable product packaging made from 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
