Enhance workpiece grip, stability, and versatility on precision modular machine vices with industrial-grade Jaws for Modular Vices (replaceable modular vice jaw inserts / grooved clamping plates). Engineered to fit standard precision modular vices, these hardened steel jaw inserts feature specialized horizontal and vertical grooving along with precision-ground contact faces. Designed to bite securely into unmachined stock or locate smoothly against pre-machined surfaces, they work in tandem with pull-down vice mechanisms to ensure rigid, slip-free workpiece clamping during heavy milling and grinding operations.
