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.

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 plates.

High-Precision Cross-Slide Drill-Press Vises
The dials on these vises are graduated in smaller increments than standard cross-slide drill-press vises for finer adjustment. Turn the handles on the base to precisely position work on X and Y axes for drilling, tapping, and reaming applications. Turn the threaded main screw to move the jaw. Vises mount directly to your drill press.

Sine Vises
Lift the end of these sine vises by placing gauge blocks underneath—they hold tools and workpieces at precise angles for grinding, cutting, and inspecting. To determine how high to raise the end, multiply the sine of your desired angle by the distance between the vise’s dowels, which is the hypotenuse. They have a locking bar you tighten with a 5/32" hex key (not included) to secure the angle. Mount them to your work surface, or when you need to cut material on a compound angle, to a sine plate.
To grip workpieces—even small round parts such as pins and dowels—these sine vises have a jaw with horizontal and vertical V-shaped grooves. Adjust the jaw to workpieces of different sizes by loosening its screw with a 1/4" hex key (not included), sliding the jaw into position, and tightening the screw for a firm grip.

Cushion-Grip Precise-Control Pin Vises
A rubber-covered body provides a comfortable grip. Press the rotating end cap on the handle with your palm to apply constant pressure while turning the body of the vise with your fingertips. Turn the collar to close the collet around the material.

Parallels
Place a parallel against each vise jaw to create a rest for your workpiece. Precision ground to tight tolerances, these matched pairs raise the workpiece within a vise to allow more clearance for cutting tools.
Parallels with four precision-ground sides have tight parallel tolerances on the top edge, bottom edge, and both faces.
6" long parallels are ground to 0.0001"; 12" long parallels are ground to 0.0002".
