Pyramid Tong Die 3/8″ x 1″ x 7-5/8″ | Extra-Long API 7K Insert
The 3/8″ x 1″ x 7-5/8″ Pyramid Tong Die is an extra-long gripping insert engineered for high-torque drilling and well-servicing applications. Its extended 7-5/8″ length provides a massive contact area, distributing clamping forces more evenly across the tubular to ensure a secure, non-slip grip while protecting the structural integrity of your drill pipe and casing.
Description
Comprehensive Technical Data
Advanced Pyramid Tooth Engineering
In the demanding environment of the rig floor, standard-length dies may not provide enough surface engagement for heavy-duty torque. Our 7-5/8″ series solves this:
Aggressive Surface Engagement: Individual pyramid-shaped teeth provide a multi-point “bite” that penetrates through heavy mud, scale, and rust.
Superior Load Distribution: The extended length significantly reduces the risk of “teeth bite” damage and pipe deformation by spreading the radial load over a larger surface.
Controlled Hardening: Every die is forged from premium 8620 alloy steel and case-hardened to 58-62 HRC. This ensures the teeth remain sharp while the core remains ductile to absorb high-impact shocks.
