Rock Auger
This tool was developed
to give maximum penetration at a constant rate while digging in hard
soils and rocky ground conditions. The carbide tipped teeth are set
on an increasing spiral configuration to give a constant cut at a
staged rate during penetration.
Kelly Box
Top end of solid steel mandril is squared and inserted into the Kelly
Box thus giving maximum resistance to shear. The Kelly Box is manufactured
from heavy plate to suite customers dimensions.
Flights
The lead flights are manufactured from 40mm plate and succeeding flights
are 30mm thick. A carbidetiped pilot is fitted as standard
Double helix construction is used for all but the smaller diameter tools.
