Was looking for a similar product that screwed onto my current grinder. I couldn't find an exact replacement for the Polishing Flap disk, so was a little wary about purchasing this one.
I installed it like I would a grinder disk and took it to a Church volunteer service project to sharpen my shovels during the project. while using another persons shovel, I realized that they had never sharpened this shovel. I asked if they would mind if I sharpened it for them and they agreed. After sharpening this shovel, 3 other volunteers came over to have their shovels sharpen with this Flap Disc.
One even commented that this was a faster than sharpening their shovel with a metal file and hand held sharpening stone.

This product performs as advertised. I used it to remove paint and galvanized finish from a piece of channel that came from an old boat trailer, something I have done often with grinding wheels. The good news...the flap disc is MUCH faster, leaves a better finish and doesn't remove as much of the substrate material. I also used the disc to round over the edges of the channel, a chore which it handled well (just keep track of the disc rotation direction and the point of contact on the work piece when working on the edge). The bad news...make sure your angle grinder can accommodate this disc. I first tried using my oldest grinder, which does NOT have a pilot and seat integral with the shaft, relying on the two sided threaded nut to pilot the disc to a truly centered position (this disc does NOT have an integrally threaded portion to attach directly to the angle grinder). I did install it onto another, newer, angle grinder (that I usually reserve for cutting wheels) and, as it DID have an integral pilot bushing/seat on the shaft, it fit well and operated as intended. As a comparison, I performed the same removal operation using another, premium, disc and noted that the removal rate and surface finish were almost identical. The premium disc is integrally threaded (mounts directly to the tool shaft and doesn't require wrenches) and has a plastic backing plate which can be cut back to restore the "flap" flex needed after the disc has been worn down. The economics of choice will differ from user to user and, especially for the home shop user, the Diablo disc will prove to be an adequate choice.

Does what it is supposed to do. I used this with my angle grinder to take down the surface of some bricks and paver stones in order to taper the edges. Did a real good job real fast. The grinding disc has a 4-1/2in. diameter with a 60 grit ultra coarse finish. It is a conical design and recommended 12,000 rpm max and a 7/8in arbor. Also works well on metal and stainless steel to. Well made.

Works well as a smoothing grinding wheel on steel welds. Hard wheels leave scratches & gouges. This wheel gives a much better finish. It does remove metal easily - so you have to be careful.

We had a shop fire and are salvaging some of the steel brackets and pipes that perform as hangers for all sorts of things on the walls. We have found that if we put the steel piece in a vice and work it over with this flap disk, the steel is ready to paint in no time and can be put back into service. It works especially well on irregular shapes where a regular wheel leaves misses. Although it looks like it would wear out, it hasn't shown any signs of wear yet and we're very pleased with its performance.
