Mining and construction manufacturer and servicer Epiroc has released its new Grey line drill bits specifically developed for European quarrying and surface construction drilling conditions. Epiroc says in a release that the line, manufactured with high-quality steel, can help increase rock drilling efficiency and is ideal for less-demanding rock conditions.

The company says the new drill bits are compatible with Epiroc’s industry standard T-thread drill string. They can be use on the Epiroc Yellow line rods, and on other manufacturer’s rods using the same common thread type.

“With the new Epiroc Grey line bits, we have a fantastic opportunity to supply the surface construction segment with a product that will boost productivity, but also provide the lowest cost per meter”, says Johan Thenor, head of product marketing – Tophammer Grey Line Products, Epiroc 

The Epiroc Grey line drill string will be manufactured in four different locations, ensuring availability, and making it more accessible to customers around the world.

Epiroc serves customers in the mining, infrastructure and natural resources industries in more than 150 countries. It develops and produces drill rigs, rock excavation and construction equipment, and also offers services and consumables. For more information, visit
