Throat depth
The depth of clamping provided by a vise or clamp (see "Type").
This parameter specifies how deep the clamped part can go between the jaws or stops until its edge rests against the tool. When choosing according to the depth of the clamp, note that a large depth accordingly affects the dimensions, weight and price of the tool.
Clamping force
Clamping force provided by a vise or clamp (see "Type").
This parameter describes the force with which the fixture is able to compress the fixed parts. It is measured in kilonewtons; Recall that 10 newtons approximately correspond to a force of 1 kg, so, for example, 1.5 kN is about 150 kg.
On the one hand, the greater the clamping force, the more powerful and advanced the tool is, the wider the potential scope of its application. On the other hand, high efforts are not always required, on the contrary: when working with soft or delicate materials, it is necessary to limit the pressure force, and not all tools have such an opportunity. Therefore, when choosing, you should proceed from what materials you plan to work with and what tasks to solve. Note that for general use, in most cases, a force of 1.5 – 2 kN is sufficient; more detailed recommendations for specific tasks can be found in special sources.
