With specialist DIENES for good reason

The cutting of composites is a complex process. You always do well with knives from DIENES with regard to quality and cost-effectiveness. Fibre composites made from glass, carbon or aramid fibre, as they are used for example in boat building, aircraft construction and automotive engineering, place high demands on machining due to their complex properties. This applies in particular to the clean cutting of composites. So it is good to know that with DIENES you can rely on more than 100 years experience in the development, production and service of slitting tools.

Our product range extends from circular knives, knife holders, narrow cutting cassettes up to slitting systems. Furthermore, we are also your partner when it comes to service – from the regrinding service to kaizen analysis. Due to their unique quality, our slitting tools ensure precise cutting edges, lowest cutting width tolerances, long knife service life and they prevent deposit build-up. The result: Cutting results at the highest level, optimum process reliability, less material rejects and higher efficiency.
