Made for Jeffrey Machine’s rock augers, the sharp, angular
dragon teeth are treated with high-grade carbide. As the
auger spins, the teeth turn as well, breaking up rock more
efficiently than the traditional bullet-style teeth.
Another Jeffrey Machine innovation that’s invaluable
when crews drill into unexpected conditions is the .990 Tri-
Holder (or pocket). The holder is engineered for use with
multi-purpose augers equipped with a .990 Tri-Holder. It
accommodates three different types of teeth: the .990 dirt
tooth, the standard .990 tooth also known as C-31 and the
.990 Dragon tooth.
“The tri-pocket is perfect for unexpected conditions.
Swapping out the teeth will help eliminate damage to equipment,”
said Krueger.
Anthony Royan, a sales manager with Caisson Consultant
Inc., knows a thing or two about drilling deep foundations
into rocky terrain. He works in Ontario, home to some of the
oldest rocks on Earth. In Ontario, younger sedimentary rocks
and soils overlay ancient Precambrian igneous and metamorphic
rock which is extraordinarily hard on equipment
and wear parts.
FEATURE
“You can drill soil with a rock tool, but you can’t drill
rock with a dirt tool. Selecting the right tools for
the job is critical. Just about every order has some
customization specific to the soil and job.”
