Boart Longyear has released what it describes as “a groundbreaking” new line of surface-set bits, including 11 configurations designed to yield deeper penetration and reduced rod tripping. The company says “Surface Set XPTM bits last up to three times longer than conventional surface-set bits” and eliminate the need to use alternative bits in inconsistent ground formations.”
“Our goal was to redefine the surface-set category and set a new benchmark for productivity in soft and sedimentary applications,” said Monika Portman, Product Manager for Coring Products with Boart Longyear. “Early testing of the new surface-set bits confirms the strength of the engineering and proprietary Boart Longyear technology applied in their development.”
The new surface-set bits feature an impregnated crown with multiple layers of diamonds for a significantly increased lifespan. Its patented UltramatrixTM crown holds large, synthetic diamonds in place as it continues to cut, compared to traditional surface-set bits that use only a single layer of diamonds.
The bits’ patented RazerCutTM face design should further increase productivity by quickly exposing the impregnated diamonds. This design delivers a “sharp-out-of-the-box” performance, with exposed cutting surfaces for immediate drilling capability. By delivering superior cutting and deeper penetration, the bit’s Ultramatrix design can reduce downtime where the bit is not cutting. 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. Boart Longyear Surface Set XP bits provide a “push-through” capability in hard seams, preventing unnecessary rod trips and enabling drillers to keep their rod in the ground longer.
With better, more sustained penetration rates, drilling contractors should also realise a significant cost-per-metre advantage. www.boartlongyear.com/surfacesetxp.
