MSD new top hammer drill bit underground offers faster penetration and longer

MSD bit underground has by far outperformed all standard bits during substantial testing carried out around the world, resulting in remarkable productivity improvement.

In tests it showed a higher penetration rate and longer intervals between regrinds, so miners will benefit from a more trouble-free, uninterrupted drilling.

“The new bit averaged 37% more drill meters before being discarded, peaking at a whopping 82% in one test round,” says John product line manager for Top hammer products at MSD. “At the end of the day, it’s about getting maximum capacity from your drill rig, and we are sure customers will be happy to see what MSD BIT underground can deliver.”

MSD BIT underground is a firm response to market demand for a bit that matches the high drilling speeds enabled by ever stronger rigs and rock drills.

With that said, it will prove just as game changing for customers using older rigs with lower water pressure, if not more. The excellent productivity is partly explained by the bit’s optimized flushing capacity, made possible by the hole configuration.

Flushing efficiency is key to a high penetration rate. MSD chose the hardest steel it has ever used in a drill bit. The configuration of the bit face is such that cuttings are removed faster than ever before.

 Customers will also be making their acquaintance with MSD's new and innovative trapezoid shaped buttons, which increase penetration rate and service life compared to conventional, semi-ballistic buttons. The first launch of MSD BIT underground is the 45 mm dimension, followed by 48 mm and 51 mm and then gradually several more dimensions.
