Metal vise jaws are usually made of aluminum or soft steel. They are sometimes heat treated, anodized, or coated with black oxide. Plastic vise jaws are usually made of polyurethane (PU), a broad category of polymers that resists abrasion and solvents to varying degrees.

I made copper caps for the jaws. This vise is mounted on a piece of 3/8 steel plate inset flush with the bench top. It is held to the bench with, if I remember right, 5/8 diameter thru bolts. The plate is pulled down by a mess of 3/8 studbolts, with holes tapped into the plate.

Vise jaws are designed for use with vises, machine tool accessories that hold workpieces in place during assembly, forming, inspection, machining, or welding operations. A vise consists of a screw, level, or cam mechanism that closes and holds two or more jaws.

The new imported vises are no subsititute. A traditionaL machinist's vise should have a rectangualr ram made from a machined casting- NOT pressed steel as seems to have taken over. The ram should be a good fit in the body of the vise with little or no slop. The screw should use a heavy butress thread.

Wide spacing between the jaws is used to accommodate longer or wider workpieces. Most vise jaws are black, silver, or gray in color; however, products that are made of die-cast metal are sometimes available in red, blue, green, or yellow.

Precision Slide Bar. OVERVIEW. Proudly made in the USA, the Machinist vise is designed to handle the most demanding clamping applications. Unlike most vises that have a fixed center nut the Machinist round channel vise nut is anchored at the rear to provide straight line pull and even pressure resulting in greater durability.

A machine vise that can be rotated. An engineer's vise, also known as a metalworking vise or machinist's vise, is used to clamp metal instead of wood. It is used to hold metal when filing or cutting. It is sometimes made of cast steel or malleable cast iron, but most are made of cast iron. However, most heavy duty vises are 55,000 psi cast steel or 65,000 psi ductile iron. Some vises have a cast iron body but a steel channel bar.

The round channel design also allows for a completely enclosed spindle and nut assembly which keeps debris out and lubrication in for a lifetime of smooth operation. The Machinist vise is equipped with main jaws and a machined anvil work surface.

This is mounted on a freestanding pedestal made of 4 steel pipe topped with a piece of 3/4 steel plate. The base is a large steel blind flange- a round solid pipe flange about 24 in diameter x 2 thick. By having the vise on this pedestal, I can move it around to where I need it.

Both the main jaws and the pipe jaws are fully replaceable. The Tradesman vise is also equipped with a swivel base with dual locking nuts. The open locking design of the Tradesman base allows for a full 360 degrees of rotation.
