Sandvik Mining and Rock Solutions is launching Sandvik Alpha\u2122 340 asymmetric drilling tools, a new thread concept within its top hammer drilling offering for mining and tunneling. Replacing the proven Sandvik Alpha\u2122 330 thread system, the new concept delivers up to 30 percent longer service life and increased productivity.<\/strong><\/p>\n

The new Sandvik Alpha\u2122 340 thread is designed for use in face drilling and bolting in mine development and tunneling, with hole sizes ranging from 43-51 millimeters. It 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, saving both time and effort. Perhaps the biggest potential lies in the increased service life of the drill rod: with Sandvik Alpha\u2122 340, customers can achieve up to 30 percent longer service life \u2013 significantly increasing productivity and reducing cost per meter advanced.<\/p>\n

\u201cThe Sandvik Alpha\u2122 330 concept has served our customers extremely well over the past 20 years, ensuring highly reliable and productive drilling,\u201d said Robert Grandin, Product Manager Top Hammer Underground Rock Tools at Sandvik Mining and Rock Solutions. \u201cWith 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.\u201d<\/p>\n

The new thread concept also comes with improved drill bits. Sandvik\u2019s successful PowerCarbide\u2122 grades will be more widely available in the standard assortment, and many bits get design upgrades with more gauge angles or larger buttons for increased robustness.<\/p>\n

\u201cThe new system is the driller\u2019s choice,\u201d Grandin said. \u201cIt is very user-friendly and provides easy uncoupling \u2013 which saves a lot of frustration for the driller \u2013 but also increases productivity, leading to better drilling results.<\/p>\n

The new Sandvik Alpha\u2122 340 thread concept will replace its predecessor Sandvik Alpha\u2122 330 in a phase-out process over the coming quarters. The new products are available for order today.<\/p>\n
