Gasket cutters are manually operated tools used for cutting gaskets.
Types of gasket cutters include compass-style circle gasket cutters, bit brace circle gasket cutters, hollow gasket cutters (or hollow punches), and more sophisticated gasket cutting machines.
Compass-style circle gasket cutters have an aluminum frame that contains a graduated scale and a steel pivot pin. They can cut a wide range of diameters in plastic, paper, rubber, leather, wood, and other materials.

Bit brace gasket cutters are used for cutting circular gaskets. They are adjustable for different circle diameters, and are similar in construction to a beam compass used for mechanical drawing. They have a steel pivot pin and a one or two cutting blades and are used for cutting plastic, metal, hardwood, and other materials.

Gasket cutting machines are more sophisticated cutters. They are usually bench mounted and actuated by a handwheel. They may contain a gearing arrangement used to create higher forces for cutting heavier materials.

When choosing a gasket cutter it is important to consider the type of material since most cutters are not designed to work on metallic and non-metallic materials, the size needed for the job and if an extension is needed, and if additional components are required.
