OTT+HEUGEL Circular Knives

Over the last decades, OTT+HEUGEL had established a leading role in manufacturing circular knives, well-known by the brand names DuraCut®, CarboCut® and CeramCut® The typical application is to find in the paper and corrugated industry as well as in the rubber and electronic industry.

DuraCut® Circular Knives are available in different steel qualities like HSS/DMo5, HSS-E/EMo5Co5 and various tool steels. All Circular Knives will be produced for customers special application from diameter 50 mm up to 570 mm. Typical applications are edging, trimming, length and cross cutting of paper, cardboard materials, plastics, rubber, leather, plasters and bandaging material, textiles, fitted carpeting, floor coverings and wire gauzes.

CarboCut® Circular Knives are supplied in high premium Solid Carbide quality. These Circular Knives are designed for high precision automatic cutting lines and wherever tight tolerances are required. All Circular Knives are manufactured from diameter 50 mm up to 300 mm. Different coatings are also available. Typical applications are for the automotive and electronic industries.

CeramCut® Circular Knives are high precision cutting tools made of ceramic. These tools are individual solutions and are characterised by their extreme high mechanical hardness and wear resistance. The basic materials are different selections of oxides, carbides, etc. These tools are supplied up to a maximum diameter of 200 mm.

Circular Knife Definition



Surface Technology and Coatings

The circular knives made of HSS and solid carbide are available with different coatings depending on the application. Coated circular knives are mainly used in order to reduce the friction and to improve the sliding behaviour. Beside the thin layer coatings such as CONCEPT based on titaniumnitrid there are also anti-friction coatings available such as Teflon etc.
