Richard R. ★★★★★ Oct 22, 2026

The threaded 1/4-20 shank locks in tight with zero wobble, which I appreciate on a die grinder. The 2-inch ones are perfect for smoothing tight corners and the 80-grit cuts fast without loading up.

I picked up a 10-pack of the 2-inch, 60-grit discs for detail work on my metal brackets, and the threaded shank makes swapping them out on my angle grinder effortless. These hold up well on weld seams without breaking apart.

I've been using the 3-inch, 80-grit flap disc on my die grinder for some light deburring, and it holds up way better than the sanding pads I used before. The threads on the shank are clean and engage smoothly with no wobble.
