SALT LAKE CITY, Utah – Boart Longyear unveiled its next generation of surface-set bits at the PDAC convention held earlier this month in Toronto. The new line of bits are said to last up to three times longer than conventional surface-set bits. Even better, using them may eliminate the need to use alternative bits in inconsistent ground formations.

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 utilize only a single layer of diamonds.

The bits’ patented RazerCutTM face design further increases 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.

Boart says that with better, more sustained penetration rates, drilling contractors will realize a significant cost-per-meter advantage.
