Vise Jaw Insert .375″ x 1″ x 4.25″ | American Augers & Astec
The .375″ x 1″ x 4.25″ Vise Jaw Insert is a high-precision gripping component designed for heavy-duty Horizontal Directional Drilling (HDD) breakout systems. Engineered specifically for American Augers (DD70, DD100) and Astec (3238) rigs, these inserts provide the aggressive mechanical bite required to handle high-torque make-up and break-out of drill pipe connections.
Description
Comprehensive Technical Data
HDD Performance Metallurgy
Breakout systems on mid-sized HDD rigs face extreme rotational stress and abrasive drilling fluids. Our inserts are built to survive:
Aggressive Tooth Geometry: Features a precision-machined pyramid or coarse tooth pattern that cuts through bentonite, drill cuttings, and rust for a fail-safe grip.
Specialized Heat Treatment: Every insert is forged from premium alloy steel and case-hardened to 58-62 HRC. This ensures the teeth maintain their sharp edge while the inner core absorbs the high-impact “snap” of hydraulic breakout cylinders.
Precision Dimensions: Manufactured to exact .375″ (3/8″) thickness and 1″ width to ensure a perfect fit in the jaw holder, preventing “chatter” or movement during high-torque operations.

Key Performance Advantages
Universal Rig Fit: Seamlessly replaces original equipment inserts on American Augers and Astec utility rigs.
Extended Wear Life: The high-hardness surface prevents “rounding off” of the teeth, significantly extending the time between maintenance cycles.
Drill Pipe Protection: Designed to provide maximum torque transfer with controlled penetration, reducing the risk of deep scarring on the drill rod.
Corrosion Resistance: Coated with a protective industrial finish to prevent oxidation during storage and wet drilling conditions.
Primary Applications
Directional Boring: Critical for gas, water, and fiber optic mainline installations.
High-Torque Breakouts: Reliable performance for breaking stubborn pipe joints in rock or hard soil.
Field Replacement: Standard dimensions allow for rapid “drop-in” installation to minimize rig downtime.
