I recently purchased the NEIKO 11142A Zirconia Flap Discs, and I have to say, they exceeded my expectations. The quality of these discs is impressive—they're durable and hold up well under high pressure and heat. I used them for grinding and sanding metal, and they performed flawlessly, removing material quickly and leaving a smooth finish.The angled Type 29 design is particularly useful for shaping edges and grinding contours. It feels like the discs were designed with precision in mind. The fiberglass backing plate is another great feature—it absorbs vibrations and prevents smearing, which makes the whole process smoother and more efficient.Overall, these flap discs are a fantastic value for the price. If you're looking for reliable and high-performing discs for your angle grinder, I highly recommend giving these a try.

Sturdily, well constructed flapper disc.
Purchased for sharping mower blades. Fit and quality appear good and first disc easily sharpened two blades and provided a good grind quality. It still has a lot of use life left.

Excellent!!!!!
Absolutely LOVE these discs, they work fast and grind anything from metal to wood down super fast. They are average thickness in comparison to similar products. Last for a long time. They seem to be tear resistant as hard as I have used them but they do wear down over a long time of use. Great stuff!

Worth the money
Actually very good quality. Better than the more expensive ones from Home Depot. Not sure why they got negative reviews
