Vise Jaw Insert 0.5″ x 1.25″ x 3.875″ | Vermeer & Universal HDD
The 0.5″ x 1.25″ x 3.875″ Vise Jaw Insert is a heavy-duty gripping component designed for the most demanding Horizontal Directional Drilling (HDD) breakout systems. Engineered for high-capacity rigs including the Vermeer D50/100, D80/100, Universal 160/240, and DD110, these inserts provide the aggressive mechanical bite required for high-torque pipe connections in challenging soil and rock conditions.
Description
High-Torque Engineering
On larger HDD rigs, the breakout system must manage massive clamping forces without slippage. Our 3.875″ inserts are built for peak performance:
Aggressive Tooth Geometry: Features a deep-etched pyramid or coarse tooth pattern that penetrates through thick drilling mud, bentonite, and pipe scale for a fail-safe grip.
Dual-Action Heat Treatment: Forged from premium alloy steel and case-hardened to 58-62 HRC. This creates a razor-sharp biting edge supported by a shock-resistant inner core to prevent brittle fracturing under hydraulic pressure.
Precision Fit: Machined to a strict 0.5″ (1/2″) thickness and 1.25″ width to ensure a perfect seat in the jaw holder, eliminating vibration and “chatter” during breakout.

Key Performance Advantages
Universal Rig Compatibility: Seamlessly replaces OEM inserts on Vermeer and Universal utility/pipeline rigs.
Extended Service Life: High-hardness tooth edges resist “rounding off” in abrasive environments, significantly reducing maintenance downtime.
Optimized Torque Transfer: Engineered to provide maximum grip with controlled penetration, protecting the drill rod from excessive scarring or stress risers.
Corrosion Protection: Treated with a high-durability industrial finish to prevent rust during storage and wet-weather drilling.
Primary Applications
Pipeline & Utility HDD: Essential for large-diameter gas, water, and infrastructure installations.
High-Torque Breakouts: Reliable performance for breaking over-torqued or stubborn joints in hard formations.
Field Serviceability: Standardized dimensions allow for rapid “drop-in” installation on the rig floor.
