Coarse Tong Die 3/8″ x 1″ x 4-1/4″ | Web Wilson Type C & D
The 3/8″ x 1″ x 4-1/4″ Coarse Tong Die is a high-strength gripping insert engineered for precision performance in Web Wilson (Type C, D, and ADF) and BJ manual tongs. Featuring deep-etched coarse teeth, it provides the aggressive mechanical penetration required to secure drill pipe and tubing strings in high-torque environments, especially when surface contaminants are present.
Description
Comprehensive Technical Data
Advanced Grip Engineering
For smaller tong configurations, maintaining a secure grip is critical to prevent pipe damage or rig floor accidents. Our Coarse series offers:
Deep-Bite Technology: The coarse tooth geometry is specifically designed to cut through thick drilling fluids, rust, and scale, ensuring direct steel-to-steel contact.
Controlled Metallurgy: Forged from high-tensile 8620 alloy steel and precision case-hardened to 58-62 HRC. This allows the teeth to remain razor-sharp while the ductile core absorbs high-torque shock.
Self-Cleaning Design: The wide valleys between teeth facilitate the rapid discharge of debris, maintaining a constant coefficient of friction.
