Benchmark Abrasives 3 Inch Sanding Discs Quick Change Nylon Surface Conditioning Discs, Drill & Die Grinder Sanding Disc Rust Remover for Metal Paint Stripper & Removal, Polishing - (25 Pack)(Medium)

good discs works as designed

I have only used one of these so far, but it has performed well. I use these to remove old gasket material and prepare items for new sealant or gaskets. So far I have cleaned up an intake manifold, set of heads, oil pan and block, front cover and other small items and there is very little wear of the original disk.

These are 80% as good as 3M but a fraction of the cost.

In my industry of work, which is agriculture & construction equipment, there is a ton of materialistic work that needs to be done. This includes changing oil, welding, repairing, and grinding / sanding some of the equipment. These are the best sanders that we use because of there strength. They do not bend or get frail after a couple of uses, and they always keep a clean streak. If you need to sand any piece of metal down, I would highly recommend these due to their durability.

As good as 3M

As described.

Great for cleaning parts.

Made with great material
