Review on Aluminum Oxide Resin Grinding Sanding by Michael Robinson

Revainrating 2 out of 5

Do not work with hardened steel.

Bought these to try and save $. The ones I usually use are $154 a pack. I use them to sharpen the teeth of a forestry mulcher. They won't work, they can work on softer metals like lawn mower blades.

Pros
  • USE: Our RFDs are designed for use with an angle grinder and should only be used with the backing pad and nut. Aluminum Oxide is the original metalworking abrasive and is recommended for small jobs where a strong, inexpensive product is required.
Cons
  • Price piggy bank
