Milling-Machine Vises
Use these vises for reliable workholding on CNC machines.
Premium vises are the industry standard for precision CNC milling and are made in the U.S.A. They're designed to prevent jaw lift, keeping the workpiece seated firmly on the vise bed as the jaws close for precise machining. You can also attach the jaws to the outside ends of the jaw holders to hold a wider workpiece.
Economy vises reliably position workpieces but don't provide the precision and tight tolerances of premium vises. They are imported.
Vise with swivel base rotates 360° in 1° increments and can be locked in place.

High-Precision Milling-Machine Vises
The vise body and stationary jaw are one piece for a repeatable clamping accuracy of ±0.0005", even under heavy loads. Ground flat to a parallel tolerance of 0.0005" on the base and three sides, these vises ensure accuracy whether mounted on the base, either side, or upright. They are designed for use with 3- and 4-axis CNC milling machines. To hold wider workpieces, you can attach the jaws to the outside ends of the jaw holders.

Self-Centering Machine Vises
The jaws move inward at the same time to consistently position your workpiece in the center of the vise. These vises are used on Bridgeport-style milling machines and drill presses. The base swivels 360° and locks in place.

Machine Vises
Our basic machine vises, these are used on Bridgeport-style milling machines as well as drill presses and surface grinders.
Vises with smooth and grooved jaws have one smooth jaw and one grooved jaw for clamping flat, round, and uneven workpieces.
Vises with swivel base rotate 360° and can be locked in place.

Air-Powered Machine Vises
Compressed air controlled by a foot pedal allows hands-free operation. Step on the pedal to instantly close the moving jaw; step again to release it. Use these vises in production applications with frequent insertion and removal of workpieces on Bridgeport-style milling machines and drill presses. Vises with a jaw height of 1 1/4", 1 5/16", and 2 1/2" can also be used on surface grinders.
To calculate the gripping force on your workpiece, multiply your inlet air pressure by the gripping force factor. Add an air regulator to control force.
Single-acting vises require the jaw to be manually set to the desired position before use, so these vises are best for repetitive clamping of consistent workpiece sizes. Once the jaw is set, activating the air pressure will move the jaw up to 5/8" to clamp. When air pressure is released, a spring return inside the air cylinder returns the jaw to the set position.
Double-acting vises use air pressure to open and close the jaws without manual adjustment, making these vises a good choice when clamping workpieces of varying size.

Ultra-Precision Machine Vises
Designed for precision grinding and inspection, the construction of these vises ensures workpieces are held perfectly square. To move the jaw, remove the screw using a 1/4" hex key (not included) and manually slide the jaw into position. Then replace the screw and tighten to firmly grip the workpiece. The base and three sides of the vise are ground flat to a parallel tolerance of 0.0002", enabling mounting on its base, either side, or upright. Mount through the base with screws or use setup clamps (not included). Vises can be used on Bridgeport-style milling machines as well as drill presses and surface grinders. They are also known as toolmakers’ vises.
