Spiral Flush

PPV Finland designs, develops and sells innovative contracting tools for the foundation and well drilling industries. The products are especially useful for complex ground conditions, and where ground disruption must be minimized, such as heavily built up areas, or off-shore works. Utilizing the patented “Spiral Flush” technology the PPV products offer significant advantages vs. conventional DTH tooling. Some of the advantages of this revolutionary technology are;


  • Flushing improves drilling speed
  • Drilling speed enhances pilot bit life
  • Cutting edges improve drilling in hard clay
  • Spiral grooves push material out when rotating


  • All cuttings and flushig air are kept inside of the casing - so there is no air escape to the surroundings 
  • Removes the danger of over drilling (sandy formations) 
  • Removes the danger of air escape (clay formations)
