Our circular knives are heat-treated to a hardness of 56 to 64 HRC in accordance with their diverse uses. Our rotary knives can be surface-treated with teflon or PVD coatings, while some of our circular knives are made without surface treatment.

If these rotary knives are employed in the grocery industry (for example, in the production of canned vegetables or circle knives for cutting deep-frozen products like fish, pork, etc.), they are made from stainless steel and range in diameter from 20 mm to 600 mm.

Given that these industrial knives are only made upon request, it is crucial to include the following information in client queries or orders:

the circular knife's diameter

the circular knife's thickness, central bore diameter, driving pin hole diameter, number, and pitch; 

the material that should be used for the body of the circular knife; 

the circular knife's cutting edge variant; its cutting geometry; 

the length of its cutting edge; and the type of material that the circular knife cuts;


The typical modification does not disrupt the industrial knife's cutting edge. It can have teeth like those seen on HSS circular saw blades for metal cutting, or it can have very particular tooth shapes. It is possible to create circular knives without teeth, as well as circular knives with grooves or ripples on the cutting edge.

Depending on the type of material that the industrial knife is cutting, these blades' cutting edges change.


Our circular knives are suitable for a variety of applications.Stainless Steel circular knives are available in the Poultry Processing section of this website for use in the poultry processing industry.

Circular knives are used in a wide range of industries, including tobacco, packaging, poultry, carpet, tissue, paper, rubber, and printed circuit boards.

There are plain circular knives as well as circular knives with dished tops and bottoms.
