How to choose?
When choosing, you should pay attention to the following nuances
Material. It is best to choose a cast iron tool with steel jaws.
The size of the fixing jaws. Before buying, you need to decide on the purpose of the tool. The choice of the jaw size is based on the dimensions of the workpieces to be processed.
Mounting method. For carpentry and locksmith work, choose a vice with a screw clamping mechanism. They are comfortable and do not require maximum effort when working. There are models that allow you to adjust the fixing of the part with one hand. For more serious and frequent work, it is recommended to use stationary models that are attached to the workbench.
Versatility
When working with workpieces of different shapes and materials, you should pay attention to the universal clamps. As a rule, these vices are equipped with replaceable jaws.
Tool size
Small and lightweight instruments are recommended if the clamp is to be moved.
Quality. An important factor when choosing. It is necessary to pay attention to the surface of the vice, to the condition of each detail. The tool must be free of defects, scratches, distortions. Quality product has the correct shape with clear straight lines. Threaded elements must be coated with grease. Movable mechanisms are smooth running.
The price depends on the destination. For professional purposes, it is better to purchase a more expensive model. For infrequent use, inexpensive models will do.

Peculiarities
Vise-clamps - an auxiliary tool that secures workpieces during carpentry and locksmith work. The vise design consists of two elements: a frame and a clamping mechanism. The frame provides the rigidity of the tool, and the clamping mechanism securely fixes the part. The body is equipped with fixing jaws, between which the workpiece is located. One jaw is motionless, the other is running. The movement of the lead jaw is carried out by rotating the lead screw with a handle.
There are models of vise-clamps for working with metal. They have different clamping forces and jaw widths. To fix larger metal workpieces, a tool with a large grip is used.
Some manufacturers produce anti-slip clamps. Such a tool is used to work with large parts. A special protective layer eliminates the change in the position of the part and its slipping.
All tools have their own characteristics and purpose. It is worth familiarizing yourself with the varieties of clamps-clamps in more detail.
Materials and sizes
Vise-clamps have a clamping property, the strength of which depends not only on the structure. The reliability of the clamp also depends on the material of manufacture.
Vices are made from the following materials.
- Cast iron is considered the most common vise material. Cast iron products are massive and durable, they can last for more than a dozen years.
- Steel. Cheaper clamps are made from low carbon steel. In the manufacture of expensive products, high-quality, durable steel is used.
- Aluminum / duralumin. The materials have low strength, therefore, small vices are made from them, the clamping force of which is not too high. They are used in the repair of electronic devices or for jewelry work.
- Wood. Wooden clamps are used when working with wood. Wood vise does not deform products. The whole structure is made of wood, except for the clamp screw.
The parameters of the clamps are important. Key parameters - jaw width and stroke
Based on these parameters, the depth and width of the workpiece are determined.
The sizes of the clamps are different. Some models have a jaw size from 50 mm. The maximum grip is 250 mm. The clamping force varies between 15-55 F. The length of the vice can reach 667 mm, height - 311 mm.
A vice is considered small if its length is 290 mm, height - 140 mm, jaw stroke - 50 mm. The average vice has dimensions - 370 mm, 180 mm, 126 mm. The parameters of large clamps are 457 mm, 221 mm, 161 mm.
