Terelion, a manufacturer of rotary drill bits to the mining industry, is gearing up to expand into the down-the-hole (DTH) market with its latest product release at MINExpo 2021 in Las Vegas.

In addition to the existing rotary bits range, Terelion now offers the Warrior product line of DTH hammers and bits in sizes from 4-8 in (102-203 mm.

Traditionally, DTH is used for drilling up to 10 in production blastholes in quarries and surface mines, with the ability to drill fast with minimum hole deviation in hard and fissured rock earning its popularity. It is also used for drilling pre-split and buffer holes in large surface mining operations where production drilling is done by rotary.

Rahul Obla, DTH product line director at Terelion, said: “This makes our new Warrior DTH range a perfect complement for our customers, who mostly use our rotary tools in their production drilling.”

Introducing the Warrior DTH product line with a full range covering 4 in, 5 in, 6 in, 7 in and 8 in hammers is a natural step for Terelion’s new growth strategy, it says.

“Having both rotary and DTH offerings allows Terelion to be the productivity partner of choice for large mining customers who use both methods of drilling,” the company said.

Obla added: “Our rotary drilling customers appreciate our premium product offering and committed way of doing business. Now they can get their DTH tools in the same way from us as well. And, of course, we address any operations using DTH also for production drilling that seek an agile and committed tools supplier.”
