Boart Longyear Ltd. offers a new line of surface-set bits, including 11 configurations designed to yield deeper penetration and reduced rod tripping. The new surface-set bits feature an impregnated crown with multiple layers of diamonds for an increased lifespan. The Ultramatrix crown holds large, synthetic diamonds in place as it continues to cut. The bits’ RazerCut face design further helps increase productivity by quickly exposing the impregnated diamonds.
