A key advantage of the aluminum construction is that it prevents the magnets from magnetizing any steel parts held within the jaws. This ensures that the workpieces remain unaffected by magnetic fields, maintaining their original properties and quality. The combination of these features makes the jaw inserts an essential accessory for any gunsmith looking to enhance their bench vise's functionality.

Polyurethane prism jaw inserts are engineered to securely clamp delicate round and oval workpieces, minimizing the risk of surface damage during precision machining or assembly operations
Prism-shaped cutouts of varying sizes in the polyurethane facilitate the secure positioning of workpieces
The highly flexible soft polyurethane face resists deformation and permanent set, promptly reverting to its original shape post-pressure and maintains its pliability without hardening over time
