One of Caisson Consultant’s most successful wear parts
is the BK47-02 tooth because of its ability to chomp through
rock. The teeth are hot dipped in high-quality carbide powder
which creates a rough surface area, enabling better rotation.
The design and coating help to maintain the sharp cutting tip
for more linear drilling metres with teeth consumption.
“It’s been a great success in the Canadian market,” said
Royan. “We sell 3,000 to 4,000 of them a year.” Royan has
received feedback from customers that for every 10 to 12
metres of rock drilled, just two to four teeth will need replacing.
Most small, 540-millimetre-rock augers have around 10
to 12 teeth, but as the diameter goes up, and with a progressive
style, the number of teeth can exceed 25.
Different soil types will determine the type of auger used.
For instance, for soft to medium dense soil, a single-cut auger
with earth teeth will be most effective. A flat rock auger will
be effective for drilling a smooth, level foundation if the
rock strength is around 60 to 80 megapascal (MPa). For rock
strength above 80 MPa, a progressive rock auger will deliver
the more concentrated force required to break up the rock.
As with Jeffrey Machine, Caisson Consultant’s team provides
recommendations based on sample corings. “If you
encounter an unexpected underlying factor, do not blame
us,” Royan joked, adding. “We tell customers to let the soil
determine the auger – and don’t mix applications.”
How to sustain the life of the equipment, tools and
If you ask manufacturers how long equipment, tools and
wear parts will last, they will invariably say, “It depends.” It
depends on the applications. It depends on the competency
of the operator. It depends on whether the core samples give
the team the information they need for seamless execution
of the project.
Of course, selecting the right equipment for the right application
is the first step to prolonging the life of equipment,
but daily maintenance is also essential. “Daily maintenance
involves inspecting the tool in the morning before the work
begins and as it comes out of the hole every time you drill,”
