Nut splitters: everything you need to know

Depending on the type of the mechanism:

• Mechanical. As a rule, they are cheap.
• Hydraulic. They make it possible to remove even large and durable fasteners quickly without much effort.

• Ring frame. These are tools with a frame that fully encircles a nut.
• C-frame. Thanks to the C-shaped frame, these tools are easy to place on and off the nut to be removed.

The body of both these models might be of the following types:

• Straight nut splitters. They are characterised by the simplicity of design. Sometimes, it is not very comfortable to use them if the fastener protrudes above a large flat surface.
• Angle nut splitter. These models feature the handle and frame placed at a small angle. This is a good option if you have to work in tight spaces.

Depending on the features of the working part, the following main kinds of the tools can be distinguished:

• with a movable chisel and fixed or adjustable anvil;
• with a movable anvil and fixed chisel;
• with two chisels: fixed and adjustable.

Operating principle

The main element of the tool is a chisel that splits the nut gripped by the frame. Mechanical models work due to the screw being turned, hydraulic devices are powered by the pressure of the liquid. It is contained in the hydraulic cylinder and, when the handle is operated, actuates the working element. If it is necessary to return the chisel to the initial position, the shut-off valve should be opened.
