This 150-pack of 3-inch zirconia sanding discs is exactly what you need for grinding, stripping, and finishing a whole range of materials.
You get 50 discs in each grit – 36 (coarse), 60 (medium), and 80 (fine) – so you can tackle rough removal first and then smooth things out for a polished finish.
The discs are made with zirconium oxide particles bonded in resin, which means they cut fast and last longer than cheap sandpaper.


These are super versatile.
Use them on carbon steel, cast iron, aluminum, brass, copper, hardwood, and even heat-sensitive materials.
Great for deburring, surface flattening, mold grinding, and removing rust or old paint.

Whether you're a professional fabricator or a weekend warrior, having a variety of grits on hand saves you trips to the store.
