Circular knives.

Applying. All round view.

Whether made from steel, powder metallurgical steel (DPM), tungsten carbide, special materials or finished - our circular knives always represent perfection. In up to 40 operations and using the latest technology we manufacture highly effective products which impress in long-term use with precise and clean cutting edges. Our comprehensive pre-delivery quality checks also guarantee that there are no tolerance variations of any kind to adversely affect the performance of the slitting tools.

DIENES circular knives are available for various applications up to a diameter of 500 mm. Our large and continuously fully optimised standard range includes numerous top and bottom knives for shear cut, score cut / crush cut, burst cut and razor blade cut procedures, matching high-quality multiple knife blocks for carrier shafts and expanding air shafts, as well as rotary shear knives. Collars, cutting rings and spacers as well as glass-hard shafts and rings are also produced by us with highest precision. Along with our standard products, we also regularly manufacture circular knives which are developed for special applications or new machines, exactly in accordance with the customer's requirements.
