When you're choosing among tooling cutters abrasives, the first decision is the format, not just the grit. This comparison covers an all-in-one angle grinder sanding kit from Illinois Industrial, a quick-change disc set from Goliath Industrial, and two identical industrial sanding sheet packs. The listed prices run from $17.99 to $26.99.
Quick Take
Here's the short version: the Illinois Industrial kit is the only bundled option with a pad and hook-and-loop sheets in five grits. The Goliath Industrial set is the swap-friendly specialist with a quick-change attachment in extra-coarse grit. The industrial sanding sheet pack appears in two copies and is the highest-volume choice for straightforward sheet sanding.

Product Notes
21 PIECE 4-1/2" ILLINOIS INDUSTRIAL ANGLE GRINDER SANDING DISC BACKING PAD KIT
This is the only option here that comes as a complete angle-grinder sanding setup: a new 5/8-11 threaded backing pad plus 20 hook-and-loop sheets in 40, 60, 80, 120, and 180 grit. The pad is made for 4-1/2-inch and 5-inch grinders, so it fits a common grinder size without extra adapters. The reason to pick it is variety: you get five grits in one box, which is useful when you're working through rough sanding and then finishing on the same project. The limitation is that after those 20 sheets are gone, you need to buy replacement hook-and-loop discs yourself, and the kit contains just that single backing pad.
25 GOLIATH INDUSTRIAL 3" ROLL LOCK QUICK CHANGE SANDING DISCS ZIRCONIA 24 GRIT
If you want to swap discs fast, this set of 25 new 3-inch roll-lock discs uses a quick-change format, so there's no backing pad to thread. The zirconia alumina abrasive is designed to cut with less heat buildup, which helps during aggressive stock removal. The reason to pick it is the quick-change format and the coarse 24-grit performance. The trade-off is that the entire set is extra-coarse, so you'll need another abrasive if the job moves to smoothing or finishing. You also won't get a variety of grits from this single pack.
industrial 2 packs of 50 Sanding Sheets Medium Grade 80 Grit 70370804
Volume is the main reason to choose this pack: two packs of 50 add up to 100 sheets of medium-grade sandpaper. The sheets are brown, aluminum oxide, and made in the United States, and they come in open-box condition. Since these are flat sheets, you need to supply the sander attachment yourself or cut them to fit. The limitation is a single grit and grade; there's no finer option here and no attachment hardware in the box. For someone doing a single pass of uniform sanding, the sheer sheet count is hard to match.
Industrial Sanding Sheet Pack (Second Option)
The second option for this sanding sheet pack is identical to the first: the same 100-sheet count, the same medium grade, and the same open-box condition. If you already decided on sheets, this copy gives you the same configuration without changing the specs. The drawback is that you're still getting one sheet type, and you'll need to fit the sheets to your sander or use them with your existing setup. That makes it a direct duplicate choice rather than a way to add variety.
Final Recommendation by Use Case
- For a complete angle grinder sanding setup with multiple grits, go with the Illinois Industrial kit.
- For fast disc changes and aggressive heavy work, go with the Goliath Industrial set.
- For the largest supply of plain sanding sheets, choose the industrial sheet pack; the second copy is just as usable.
