Riley ★★★★★

The 5/16" x 24 thread shank locked onto my sander without any wobble, and the super hard pad held its shape through a full day of aggressive work. It's exactly the sturdy, no-nonsense backing I was hoping for.

Elizabeth ★★★★★

I needed a backing pad that wouldn't give under heavy pressure, and this 6-inch one with its solid composition hasn't let me down yet. The 5/16" x 24 thread shank threads on perfectly every time.

Aurora ★★★★★

The super hard backing pad hasn't flexed at all under heavy use on my grinder, which is exactly what I needed for consistent flat sanding. It threaded onto the shank smoothly and stays put without any wobble.
