Sandvik Alpha™ 340 - New Top Hammer Thread

Sandvik Mining and Rock Solutions is launching Sandvik Alpha™ 340 asymmetric drilling tools, a new thread concept within its top hammer drilling offering for mining and tunnelling.

Designed for use in face drilling and bolting, with hole sizes ranging from 43mm-51mm, the Sandvik Alpha™ 340 features an entirely new asymmetric thread profile and has a larger diameter on the bit end thread of the drifter rod, reducing stress levels in critical areas. Uncoupling is also easier than in previous designs, with perhaps the biggest potential lying in the increased service life of the drill rod: with the company claiming that customers can achieve an up to 30 percent longer service life – significantly increasing productivity and reducing cost per meter advanced.

“The Sandvik Alpha™ 330 concept has served our customers extremely well over the past 20 years, ensuring highly reliable and productive drilling. With the launch of its successor, we create a revolutionizing new way of working with top hammer rock tools, thanks to its asymmetric design. This new concept will deliver both immediate and long-term value for our customers.” said Robert Grandin, Product Manager Top Hammer Underground Rock Tools at Sandvik Mining and Rock Solutions.
