Great value and heavy duty reliable product
These grit flap discs are very heavy duty and have exceeded expectations. The 40-grit is coarse enough to remove weld seams and rust quickly, yet the flap design leaves a much smoother finish than a hard grinding wheel. They hold up well on stainless steel and mild steel without disintegrating or losing grit prematurely, which speaks to the quality of the zirconia abrasive. For the price of a 12-pack, these are an excellent value compared to big-box store brands. They mount easily on my 4.5-inch angle grinder with the standard 7/8-inch arbor, and the Type 27 shape gives you that slight angle for comfortable flat grinding. Whether you're prepping metal for paint or shaping wood, this is a solid, cost-effective pack to have on hand. Read more
Very good value and high quality.
Review of: Flap Discs 4 1/2 x 7/8-Inch for Angle Grit 40 Type 27 Premium Zirconia Grinding Wheel for Steel, (10 Pack) Synopsis: Excellent value for Zirconia heavy-duty 40 grit flap discs. Suitable for wood and metal. Priced at $9.99 for a 10-pk on 10/28/25, these flap discs are an excellent value and a bargain compared to similar products. Pros: Measured dimensions are as advertised in product description. Thick fiberglass backing, low vibration, and very durable in use. Sparking is low compared to other discs I've used. Fit perfectly on my Bauer angle grinder They are durable, last a long time in use, and cut quickly. Zirconia is tougher and longer lasting than aluminum oxide discs. Perfect for material removal on flat surfaces and outside corners at shallow angles. The quality is much higher than I expected at this price point. Cons: None. Conclusion: Very good value and much higher quality than I expected. 5-Stars for exceeding my expectations. Read more
Remove a lot of material quickly, durable Zirconia grinding media.
I got these discs for sharpening blades on my lawn mowers. These flap discs are 40 grit and are quite coarse. They quickly remove a lot of material, which is perfect for sharpening lawn mower blades as you literally need to remove a lot of material to restore badly damaged apex and edges. These disks also last as flap pads are made from Zirconia grinding media which is extremely hard and maintains superior hardness under high temperatures. The discs are quite thick so you may need to remove the backing arbor nut to make some space for flying debris between the disc and blade guard lip. I also noticed that these discs generate significantly less sparks as they remove bigger material particles and generally run cooler than lower grid discs. Read more
