Circular knives
Whether made of steel, powder metallurgical steel (DPM), carbide, special materials or refined - our circular knives always stand for perfection. With up to 40 working steps, we use the latest technology to produce highly effective knives that impress with precise and clean cutting edges in long-term use.
DIENES circular knives are available for various applications up to a diameter of 500 mm.
Our large and continuously optimized standard program includes numerous upper and lower knives for shear, crush and burst cutting processes, matching high-quality cutting bushes for carrier and expansion shafts, as well as roller shear knives. We also manufacture knife sleeves, cutting and intermediate rings as well as glass hard shafts and rings with the highest quality.
In addition to our series products, we also manufacture circular knives that are developed exactly according to customer requirements for their special applications. Our comprehensive quality controls before delivery also guarantee that no tolerance deviations impair the performance of the cutting tools.
From standard products to individual special solutions, we can meet any cutting technology and customer-specific requirements.
