Powerline Drilling


Earthing Augers

TEBCO have developed a unique 150 OD x 4.2m long auger with a rock cutting head. The auger comes in 2 pieces and can be used as a 2.1m or 4.2m auger with the option of adding more sections if you require. This is great for use in height restricted areas and eliminates the need to bring in a separate machine for drilling earthing holes. This is proving to be very cost effective and useful for all operators who concentrate on the drilling for the powerline industry, but can be used in many other applications as well.

Triad & Double Rock Augers

The TRIAD series is a precision engineered auger designed and developed by TEBCO. The revolutionary design utilises three cutting edges to increase your drilling efficiency. The quality, drilling efficiency and increased consumable life, set a new benchmark for the rock and powerline drilling industries. The TRIAD is fast becoming our signature auger as the word spreads in drilling circles.

We have had instances of rigs being on site for days, drilling, drilling, drilling and getting nowhere. A recent example being a powerline site in the Greater Sydney district where an operator began drilling at 1:00pm and finished at 6:00pm, then began again at 6 am, the next day, our auger arrived onsite at 2:30pm and the hole had only reached a depth of 1400mm. The required depth was 3.8m, a TEBCO triad was fitted to the machine and within 40 minutes the operator had reached the 3.8m target, the only difference being the TEBCO triad! The results speak for themselves!

Core Barrels

For some applications such as bluestone, ryalite and granite, TEBCOre barrels are more efficient for pendulum-style borers. TEBCOre Barrels are set up by our experienced fabricators, with the cutting teeth at just the right angle for the most effective rock coring. The teeth are easily replaceable and the quality hard facing on the outside of the barrel means your core barrel will remain operational for a long time. The lower barrel which holds the cutting teeth is strengthened even more to prevent any distortion, as always delivering top quality, effective drilling to make your job easier. Please give the TEBCO team a call to discuss your needs.
