4 inch in circumferenc.
The thread size is 5/8-inch-11.
Due to the 10mm EVA semi-rigid layer, this pad is particularly suitable for high speed sanding or polishing applications.
Fastener with a hook and loop closur.
Maximum rotational speed: 1250.
Even at 2500 RPM, I was unable to keep this pad from chattering on my Makita angle grinder with variable speed control. I ended up gouging a significant amount of my work. I went back to my room. ordered and received a different one, made by Murat, and it worked just as well as the first, indicating that it was the Rotary Backing Pad and not the angle grinder or diamond pads that were malfunctionin.
I’m not sure if it’ll be sufficient for rough work, but I doubt it.
