RD-piles are designed for the toughest conditions in order to penetrate hard rock. This means, that the drill bits have to be top-notch as well.
Designed and manufactured by drillers, we know what it takes to produce the best drill bits available.
- Single Piles:
- 168mm – 1220mm
- RD-Pile Wall

Specialized pile diameters available upon request (for example 1400mm).
Our products include pilot bits, ring bits, casing shoes and ring bit sets in all diameters. Our patented Radial Flush-system does not disturb surrounding soil and has excellent pilot bit durability. This means more drilling meters per pilot bit compared to conventional ones.
