4-1/2" x 7/8" Surface Preparation Wheel

Good product

Used the fine disc to remove light rust from machinists' squares, scales, and levels that had been in storage for years. Worked great. Cordless angle grinder on low speed and a light touch made them look almost new.

Surface prep disk

Works great for aluminum prep. Especially on repairs when it has been subject to the elements. Great prior to acetone wipe down. Greatly increases repair success with TIG welding.

Work Great.

Great product once again.
