IADC637 9 7/8 tricone bits for water well drilling in stock for hard rock formations

IADC 637 (Code X) TCI journal sealed bearing tricone bit, equipped with gauge protection, is specially designed for hard formations with high compressive strength ranging from 100-150 MPa (14,500-23,000 PSI) — a core advantage reflected in end-client feedback. With a size range of 9 5/8” to 9 7/8”, it adopts tungsten material to adapt to mud circulation requirements in water well drilling, and is matched with 3-side regular jets. Clients report its excellent wear resistance and stable mud circulation, enabling efficient operation in hard formations. Meanwhile, the sealed bearing and gauge protection design extend its service life, enhancing overall drilling efficiency and cost-effectiveness.
