Basic Safety When Working with Diamond Cup and Grinding Wheels

Always wear eye, hearing and dust protection! Wear a respiratory mask if necessary! Consider using a PAPR (powered air purifying respirator).

Careless or improper use of a cup or flap wheel could cause personal injury!

  • Ensure you are wearing the correct personal protective equipment. If dry grinding, consider using a PAPR (powered air purifying respirator).
  • Make sure your work area is safely away from other workers, pedestrians, animals or any flammable materials
  • Do not use any tools if damage is suspected
  • Beware of sun damage to the operator
  • Have a fire extinguisher and first aid kit nearby
  • Do not force the wheel onto a machine or alter the arbour size in anyway. Do not use a wheel if the arbour is a loose fit
  • Install the cup wheel with the arrow pointing in the rotation direction of the tool
  • Use a cup wheel that is suitable for the machine and the material to be cut
  • Ensure you do not exceed the maximum RPM rating for the wheel
  • Check the cup wheel for suitability before grinding dry
  • Check diamond cup wheel for damage before installing
  • Check machine condition before performing any grinding operations
  • Check condition of cup wheel regularly
  • Check all electrical cords and plugs (if applicable) and protect them from water. Always use an RCD
  • Never grind without the safety guards in place
  • Do not side grind unless the wheel is specifically designed for that purpose
  • Be aware of fume build up even in open buildings
  • If you are grinding dry, always be aware of the danger of breathing in the dust. Ensure a dust extraction system is used with a suitable filter fitted. Use a half face respirator or a PAPR (Powered air purifying respirator). See our dust collection accessories here
  • If you are grinding wet, the slurry created can dry out and create a hazard for other users - dispose of slurry as per your local regulations.
