Sali’s 20 Pack 40 Grit 4.5" x 7/8" flap discs are a solid, affordable choice for general grinding and weld cleanup, but a few quality inconsistencies keep them at 4 stars instead of 5. They remove material quickly and the Type 29 bevel design makes it easier to get into edges, contours, and for weld blending and radius grinding. The 40 grit is aggressive enough for heavy stock removal while still leaving a reasonably smooth surface for follow-up sanding. Compatibility with standard 4-1/2" grinders and the 7/8" arbor size is spot on, and they handle typical grinder speeds (up to around 13,300 RPM) without issues. On the downside, in a bulk pack of 20 there are occasional discs that seem to wear out faster than others, and you can feel minor differences in balance between some of them. They still work, but you notice a little more vibration and slightly shorter life on a few pieces compared to name-brand discs. Overall, I’d rate them 4 stars: great value for the price and very usable for home shop and light professional work, just not as perfectly consistent or long‑lasting as premium brands.
