Please review maximum operating speed marked on our wheel and compare it to your grinder’s rpm.  Do not exceed the maximum operating speed of the wheel.

For concrete edge, we recommend using our concrete edge finishing cup wheel. When using the concrete edge finishing cup wheel, there should be no downward force applied to the angle grinder. Let the wheel do the grinding. The most common used process is as follow: #50, #100, #200. This process will normally match a floor that has been polished to 400 grit.

If a lot of material needs to be removed we recommend starting with the 30 grit but care should be taken when using it due to it being extremely aggressive.

If a light "salt and pepper" finish is desired the #50 is perfect to start with, followed by #200 for a mat finish or #400 for a gloss finish.

  • #30: use for heavy material remove
  • #50: use for slight material remove
  • #100: use for honing and removing scratches from previous steps
  • #200: use if mat finish is desired
  • #400: use if slightly better mat finish is desire
