Smith Bits, a Schlumberger company, released the ONYX 360° rolling polycrystalline diamond compact (PDC) cutter. This technology enables a PDC cutter to rotate 360° while drilling, improving drillbit durability in abrasive formations and extending drillbit life and footage drilled per run. The rolling cutter uses its entire diamond edge to shear the formation as the bit rotates, distributing wear over its full circumference, and allowing the diamond edge to stay sharp longer— increasing penetration rates and extending drillbit.
