MACHINERY: Top Hammer Bit

Click photo for gallery• Atlas Copco Mining and Rock Excavation, Commerce City, Colo., introduces Powerbit, a range of top hammer bits for surface drilling designed to last longer with increased performance in any rock – hard to soft, abrasive to non-abrasive.

The range features an entirely new bit shape with a harder, stronger steel bit body. Previously incorporated semi-ballistic buttons have been replaced with Atlas Copco Secoroc’s unique, trapezoid-shaped buttons – Trubbnos.

Patented Enduro Extra surface treatment allows the bit to endure all rock types. Results of 20 test series conducted at 13 sites globally, drilling more than 164,000 feet in a variety of rock conditions, demonstrated increases in service of 20% or more than leading competitors’ bits with penetration rate increases of up to 10%.

“Our power bit testing domestically and abroad has consistently demonstrated substantial improvements in bit life when compared to our old assortment, and competitive product,” says Rosss Gjerde, Atlas Copco product manager.
