Quality and Safety of Our Grinding Discs
Quality Integration with Point System
To help you better select based on your specific requirements, we offer a point system in the categories of cutting discs and grinding discs. This system evaluates the quality and performance of these grinding discs based on two key criteria: material removal rate and service life. Both factors are crucial for the efficiency and cost-effectiveness of the grinding process. The maximum achievable value for the best quality is four points.
The point ratings for material removal rate and service life can be found in the technical details of the products and are also displayed as a filter feature in the cutting discs and grinding discs categories. This allows you to specifically search for the appropriate quality level for your needs.
- Material Removal Rate: The material removal rate measures the effectiveness of the grinding disc in material removal. The higher the material removal rate, the faster and more precise the grinding process.
- Service Life: Service life refers to the duration over which the grinding disc maintains its optimal performance before replacement is required. A longer service life reduces downtime and increases productivity.
oSa Certification: Maximum Safety for Grinding Discs
All our cutting and grinding discs are oSa certified to guarantee the highest safety and quality standards. With safe and high-quality tools, you can increase the productivity of your workflows while contributing to safety and accident prevention with certified products in every application.
- Proven Safety: The globally protected oSa mark guarantees the highest level of safety when using tools for cutting, grinding, and abrasive processes.
- Compliance with Standards: Our products not only meet the strict EN standards but also go beyond them by fulfilling additional oSa requirements to ensure the highest standards.

Storage and Durability of Grinding Discs
The durability of cutting and grinding discs is primarily determined by their moisture content. Discs exposed to high humidity after production lose their original service life. With proper storage, the service life remains nearly constant over the years. Discs become a safety risk if directly exposed to water or water vapor. The age of the products plays a secondary role in this regard. Proper storage is important for maintaining the warranty and performance of our abrasives.
