Don’t use a disc larger than the maximum cutting capacity outlined below and in the product user manual, as a larger disc can cause damage to the tool, and potentially harm you or a bystander.

What to check for when fitting your disc:

  • The internal diameter of the disc must sit flush inside the inner flange. 
  • The outside diameter must have even clearance from the guard and must not touch or rub against the guard. 
  • You may use brush wheels, diamond cup wheels and flap discs, but they must meet the conventions outlined above. 
  • Removing the guard, incorrect fitment, and use of accessories with incompatible conventions can also cause damage to the tool and harm to the user. 
  • Not all Angle Grinders are equipped for cutting or grinding; check that the grinder you have is up to the task and the disc is rated for the speed that the tool can produce.
