Great success
Dragon’s Tooth four times better than rival tool

Bored pile jobs in difficult geological conditions are appreciably more effective with the ‘Dragon’s Tooth’ than with other tools. A great example of this comes from the experience on a construction site in Venezuela, where switching to Betek tools got the cost-to-performance ratio back on track.

The successful tool test is confirmed by the executives of Resansil, Betek’s business partner in Venezuela, who markets the tools. Cimarpi, a local operator, reported immense difficulties with bored pile work. They were supposed to be driving 800 piles 12 to 17 metres into the ground. But after just eight metres a gravel and quartz stratum created difficulties that could not be overcome with the tools they were using, a competitor’s flat teeth. Under these conditions Cimarpi was only managing one bored pile a day. The company’s profit margin was thus virtually nil.

A complete tool change produced a sensational impact: by using Betek’s Dragon’s Tooth BFR07 and the associated BHR 133 holder the work progressed significantly more quickly and effectively. The machine operators and workers on the construction site were very happy and reported enthusiastically on their success. They were now finally making good progress, achieving four bored piles a day. The drilling machine ran much more easily and quietly. Wear and the cost of upkeep and retooling were also substantially reduced – in turn resulting in the use of fewer personnel and linked to that a lower risk of workplace accidents.
