Work safety

Being Careful and Recognizing Risks

Please avoid the risks listed below when working with cutting-off wheels and grinding discs.

  • contact with rotating abrasive discs
  • abrasive disc breakage
  • grinding dust and debris
  • vibration
  • noise

Personal Protective Gear

Goggles, gloves, ear muffs and dust masks must be worn. When working on hard grinding applications additional protective gear is required, such as face protection, leather aprons and safety boots.

Protective Machine Guards

Machine guards supplied with the any machines may not be changed or removed. When using cup grinding wheels the outer surface must be completely enclosed.

In addition, cup grinding wheels may only be used in combination with an adjustable wheel guard, to balance the wear on the disc and to keep the exposure of the disc at a minimum.

Visual Inspection and Performance of Checks Prior to Mounting

Ensure the disc RPM matches the machine RPM setting and avoid exceeding the maximum admissible operating speed. Carefully check the cutting-off wheel and grinding disc for damage. If the cutting-off wheel or grinding disc is damaged, do not use the damaged product. Our cutting-off wheels and grinding discs are marked with the corresponding safety pictograms.

Proper Use

Ensure that the respective disc is being used properly. Avoid damage to the mounting bore or to the disc through jerks, excessive force, or falls.

Ensure that the disc is properly and securely mounted and use the correct mounting flange.

Prior to starting work, the abrasive disc should run at operating speed for at least 30 seconds.

Please observe the FEPA safety regulations and the European Standard 12413.

The peripheral speed and grinding pressure are important parameters for achieving optimal cutting-off and grinding disc results.


Keep all cutting-off wheels and grinding discs in a cool, dry place.

The shelf life of cutting-off wheels and grinding discs is primarily determined by their moisture content. Cutting-off wheels and grinding discs that are subjected to increased humidity after they were manufactured may have their original service life shortened. Proper storage ensures a consistent, long service life. Cutting-off wheels and grinding discs that are subjected to water or steam are a safety risk.
