Coarse Tong Die 1/2″ x 1-1/4″ x 5″ | BJ & Power Tong Compatible
The 1/2″ x 1-1/4″ x 5″ Coarse Tong Die is an aggressive gripping insert designed for high-torque drilling and casing operations. Specifically engineered for BJ Type SDD/C/F/LF manual tongs and heavy-duty Power Casing Tongs, the coarse tooth geometry provides a deep, mechanical “bite” that penetrates through drill pipe scale and mud, ensuring zero slippage during critical make-up and break-out sequences.
Description
Technical & Engineering Data
Aggressive Biting Technology
The “Coarse” profile features wider, deeper grooves compared to standard dies. This design is essential for:
Self-Cleaning Action: The deep valleys allow drilling fluids and debris to escape, ensuring the tooth peaks maintain direct contact with the tubular steel.
Surface Penetration: Optimized for pipes with heavy oxidation or protective coatings where a finer tooth might fail to engage.
Metallurgical Strength: Forged from AISI 8620 alloy steel and case-hardened to 58-62 HRC on the biting surface, supported by a shock-resistant inner core.
