Specially machined shaft end for maximum impact energy throughput.

Multicutter head with two additional cutting edges flanking the central HM bit plate ensures very smooth running and constant borehole geometry with optimal advance performance. Additionally, HM elements deeply embedded by high-temperature copper brazing guarantee maximum break-out resistance.

Four-channel helix allows for the best possible drilling progress through simultaneous discharge of the drill dust via four large helix channels.

Centre point enables precise, pinpoint starting.

Application examples: for circular and exact dowel holes from 16mm to 30mm.
