Tricone BitsRC Reverse Circulation Tricone Bit
RC Tricone Bit 3 7/8"
3 7/8" RC reverse circulation tricone bit, API REG 2 3/8 thread, available in IADC 637, 647 and 737. Weight 8 kg.
Reverse circulation (RC): a drilling system that recovers cuttings through the inside of the tool using reverse airflow, allowing samples to be obtained quickly and cleanly. Reverse circulation (RC) tricone bit: a tricone bit designed for exploration drilling that combines cone cutting with sample recovery through reverse air circulation. SEALED AND LUBRICATED JOURNAL BEARING WITH A TUNGSTEN CARBIDE HARDENED RACE. LEG PROTECTION WITH FLAT TUNGSTEN CARBIDE INSERTS AND ABRASION-RESISTANT HARDFACING.
