The launch of Epiroc DTH drill bits, Epiroc says, signals a new era for down-the-hole drilling, with increased productivity and profitability.

Thanks to a new design and the use of the new Epiroc carbide, these drill bits will last up to 20% longer compared with an older version of the company’s drill bits, according to the company.

An all-new face design results in optimised flushing and handling of drill cuttings, while the addition of more buttons on the drill bits increases the overall energy when drilling, Epiroc says.

There are also three different button shapes to choose from to tackle different drilling needs and types of rock: Epiroc Trubbnos, spherical and ballistic buttons.

On top of the new carbide inclusion, these DTH drill bits are produced with improved heat treatment and increased face hardness, resulting in a more durable, sturdier and robust bit, with increased service life, it added.

Fredrik Gransell, Global Product Portfolio Manager at Epiroc Rock Drilling Tools, said: “If we add up the new design features and the improved materials usage, it’s safe to say that Epiroc DTH drill bits will last up to 20% longer compared to an older version of our drill bits.”

Delaney Erickson, Global Product Manager DTH at Epiroc Rock Drilling Tools, added: “You can expect more drilled metres per shift from high-performing Epiroc bits, which is good for both your revenue and profitability.”

Longer service life also means fewer interruptions and more undisturbed drilling, one of the most sought-after improvements, Epiroc says. “Put simply, with less time spent lifting and changing heavy bits, workdays will not just be more productive, they will be more convenient too,” the company added.

Finally, Epiroc DTH drill bits reduce the customers’ footprints as they can drill more and still use fewer bits. As a result, less energy and raw materials are used to produce bits, with less waste and associated transportation.
