Each pack contains 25 sheets of 9 x 11 inches for high-volume home improvement and shop use. Model: 30220. UPC: 051144021031.
When should I use 220 grit aluminum oxide versus finer or coarser grits?
Use 220 grit for final sanding of bare wood before staining or finishing, for sanding between coats of paint or varnish, or for smoothing light surface imperfections before priming. For more aggressive material removal, use 80-120 grit first. For ultra-fine finishing, step up to 320+ grit.
Is aluminum oxide sandpaper good for hand sanding furniture?
Yes. Aluminum oxide is a versatile all-purpose abrasive for furniture. It lasts longer than garnet and cuts efficiently on hardwoods, softwoods, and MDF. The 220 grit level is especially well suited for pre-finish sanding and between-coat smoothing on furniture projects.
Can this sandpaper be used with an orbital or sheet sander?
Yes. The 9 x 11-inch sheet size can be cut to fit sheet sander pads (typically 1/4 or 1/3 sheet) or used full-size with a sanding block for hand sanding. Cut cleanly with scissors to avoid tearing the backing.
Why does aluminum oxide last longer than some other abrasives?
Aluminum oxide grains fracture under pressure to expose fresh sharp edges rather than simply dulling. This friable behavior, combined with the tough resin bond in Pro-Pak paper, extends the cutting life compared to natural abrasives like garnet.
