Diamond Bit Effective in the Hard Ground Conditions


Boart Longyear’s 10UMX bit is a high-performance diamond coring bit with the freest-cutting matrix available, enabling the bit to penetrate the very hardest rock formations in extreme conditions, according to the company.

“The 10UMX diamond coring bit completes the product range for our award-winning family of UMX bits, providing a bit for any type of ground condition encountered,” the company said. “We have tested these bits in all regions of the globe and take great pride in providing drillers the most advanced line of diamond bits in the industry to maximize their productivity.”

UMX bits are engineered to outperform existing bit technology in a wide range of drilling conditions and ground formations. UMX bits use advanced metallurgical formulas to provide increased penetration capabilities, turning easily from one ground formation to another. The optimized life of the UMX bits translates to less tripping and increased productivity.

UMX bits also utilize Boart Longyear’s patented Stage waterway design. The geometry of these windows sustains the integrity of the bit through the entire life of the bit, allowing for a variety of crown heights including the original 25 mm, providing maximum bit life. The Twin-Taper design dramatically improves surface flushing, forcing debris through the windows while keeping the bit face clear and reinforcing the inner diameter.

The Razorcut protrusions on the face of the bit contain diamonds that enable the bit to begin cutting right out of the box. The arrangement of these protrusions also improves the tracking and balance in the hole when drilling begins.
