This premium 4-inch or 6-inch Milling Machine Vise Hard Jaw Fixture provides superior clamping force and repeatable accuracy for demanding CNC and bench vise applications. Machined from high-strength aluminum alloy, its V-type jaw design securely holds round, square, and irregular workpieces, minimizing deflection and maximizing machining precision. Features and Benefits
- High-Strength Aluminum Alloy Construction - Offers an optimal balance of lightweight durability and rigidity, resisting wear while reducing overall fixture weight for easier handling.
- Precision-Machined V-Type Jaw Design - Features an integrated 90-degree V-groove to firmly and concentrically grip cylindrical stock, pipes, and round tooling without marring surfaces.
- Interchangeable Hard Jaw Format - Designed as a replacement or upgrade for standard 4-inch or 6-inch milling vises, easily swapping with soft jaws to expand your vise's capability.
- Flat and V-Groove Working Surfaces - Provides two clamping planes; use the flat surface for square stock and the V-groove for rounds, making it a versatile single-fixture solution.
- Enhanced Grip and Stability - The machined jaw face increases friction and bite, preventing workpiece slippage during high-vibration milling, drilling, or grinding operations. Applications
- CNC Milling Operations - Ideal for securing round stock for precise radial drilling, slotting, or end-milling tasks on CNC machining centers.
- Manual Mill and Drill Press Work - Provides a reliable, heavy-duty holding solution for repetitive production or prototype work on manual machinery.
- Toolroom and Fabrication Shop - Perfect for holding punches, pins, or shafts for secondary operations like grinding, deburring, or inspection.
- Bench Vise Enhancement - Converts a standard bench vise into a specialized holding fixture for working on plumbing fittings, shafts, or small-diameter tubing.
