Review on 🔵 Mornajina 5 Pack Strip Discs Stripping Wheel, 4-1/2" x 7/8", Strip Wheel Disc for Angle Grinders, Paint Rust Remover, Clean & Remove Paint Coating Rust and Oxidation for Wood Metal Fiberglass (Blue) by Ricky Rey

Summary: Used on Milwaukee M18 5" grinder for general stock removal. Currently my favorite is the flip down disc, but it can be substituted for it. As you can see on the AFTER- As you can see from the photos the wheels were abrasive enough to remove the copper base layer and get at the steel coating Recommendations: If you are working on a surface you do not want to scratch I highly recommend a test surface such as the back of the flag pole mount ( for my test case.) Pros: Runs on a 7/8" shank; aggressive removal, but not excessive. Cons: $28 for 5, they're in the mid to high range; The comparable offer is $38 for 10 discs ($3.80 each). Verdict: $28 for 5 discs, 4 stars mostly for the price.
