The Yost Vises 934-AS 4″ medium-duty all-steel combination pipe and bench vise has a 360-degree swivel base and mounts to a workbench to provide clamping action. The 360-degree swivel base adjusts the direction of the jaws for proper placement. Hand-tightening the two lock knobs on the base secures its position. The body is made of cast steel and has a black painted finish for mild corrosion protection. A flat portion on the body acts as a reinforced anvil and an additional work surface. The top jaws are made of hardened steel and can be replaced when worn, and the built-in pipe jaws are cast steel. Both the top jaws and pipe jaws are grooved for enhanced grip. The jaws draw closer together or farther apart by turning the vise handle clockwise or counterclockwise.
The main screw that controls the jaws has been continuous rolled for high strength and is covered by a bar to protect it from damage. A rubber washer on either side of the handle prevents unwanted sliding when turning, and the balls on each end unscrew to enable replacement of the handle if worn. The base has three 0.5″-diameter holes for mounting hardware (not included).
|Jaw width (nominal)||4″|
|Jaw opening (nominal)||3-1/2″|
|Throat depth (nominal)||2-1/4″|
|Pipe capacity||1/4″ to 1-1/8″|
|Overall dimensions*||5 x 5 x 13 inches (H x W x D)|
*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
Vises use the clamping action of jaws to hold a workpiece in place for applications such as drilling and sawing. Vise styles are categorized by how the device is mounted. For example, bench vises mount to a benchtop; drill press vises bolt to a drill press; and woodworking vises fit underneath, on top, or to the side of a workbench. A vise’s jaw opening and throat depth should be large enough for the workpiece.
Yost Vises manufactures a wide range of vises, including bench-mount, woodworking, and drill-press styles. The company, founded in 1908, is headquartered in Holland, MI.
