Boart Longyear has released a line of surface set bits, which include 11 configurations designed to yield deeper penetration and reduced rod tripping.
The company says Surface Set XP bits last up to three times longer than conventional surface-set bits and eliminate the need to use alternative bits in inconsistent ground formations.
Boart Longyear aimed to redefine the surface-set category and set a new benchmark for productivity in soft and sedimentary applications.
The Surface Set XP bits feature an impregnated crown with multiple layers of diamonds for a significantly increased lifespan.
According to the manufacturer, the Ultramatrix crown holds large, synthetic diamonds in place as it continues to cut, while traditional surface-set bits that use only a single layer of diamonds.
The Surface Set XP’s RazerCut face design further increases productivity by quickly exposing the impregnated diamonds.
Boart Longyear says the Ultramatrix design also can reduce maintenance downtime with its push-through capability in hard seams, which prevents unnecessary rod trips.
Hard seams in the ground often destroy traditional surface-set bits, forcing operators to pull the rod string out and change bits if ground formations vary as it cuts deeper.
