Strip Discs Grinding Disc 4.5'' x 7/8'' Stripping Wheel Clean and Remove Paint Coating Rust Welds Oxidation for Angle Grinder-5 Pack

worked great, but they dont last long, as with any of these strippers. used few different ones, they all went about the same amount of time.

Perfect to sand both rust and hard water build up on livestock plastic.

So far the best I have found for paint and rust removal from metal, you can use up the entire disc w/ even some of the backing and it doesn't leave much plastic residue or glue gunk on your project like most other of this type. They last a considerable time.

Wore down quickly and does not fit 4 1/2” grinder with guard on

These disc are very effective, but dangerous. Halfway through the life of the disc, pieces began to break off. The problem is that those pieces were traveling between 100 - 200 mph. After being hit in the face, chest and arms countless times. I gave up on it. Very short lifespan. I had the guard on.

I have an exterior metal framed door, which was in dire need of new paint. It took about 10 minutes to completely get through what appeared to be about 7 layers of different color paint. Took it to bare metal and went on to paint with in 20 minutes. Just make sure you wear a mask and eye protection!

Work like a charm. Removed powder coating no problem.

I like it. Very sturdy and lasts a long time
