Boart Longyear launches new IMPAKT rock tools bit

Boart Longyear has launched a new IMPAKT rock tools bit. 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%.

“We were fortunate to work with a major 3rd-party customer during development and testing,” said Jeff Hogan, global product line manager for Rock Tools at Boart Longyear. “Real world trials using a range of OEM drifters demonstrated alignment with our developmental testing and validated our innovation to deliver value for our customers.”

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.
