Boart Longyear announced the launch of a new IMPAKTTM line of rock tools bits. Boart Longyear continues to deliver safety, reliability, and productivity. The Rock Tools team at Boart Longyear used advanced computational modeling to identify a deadpool at the center of traditional bit designs.

This deadpool results in significant wasted energy due to inefficient flushing. The solution is the IMPAKT top hammer bit, featuring a patent pending "Raceway" face profile. Immediately recognizable as unique, the new IMPAKT bit eliminates the deadpool, improving drill string energy transfer and overall drilling performance.

After development and global 3rd-party testing, this design innovation has been proven to actively clear cuttings from the entire cutting face. With flushing speeds increased by 25%, the resulting penetration rate has been improved by an average of 18%. The IMPAKT line of tools will launch with a concise range of bits designed specifically for underground long hole drilling.

These bits are available with hemispherical or parabolic carbides in sizes ranging from 64mm to 89mm.
