    Default Aren't these roll over flap discs great?

    I'm so glad I splashed out on one of these rolled edge flap discs.

    How good are they?

    The rolled over edge and backing allows you to get right in the corners and underneath even ...luv 'm.

    Five times the price of anything without the curves, but I'm impressed.

    attached is some pics of some edge welded brackets

    Anyone else had any experience with them?

    Where did you get them? Looks like they work a treat.

    Pferd are high quality German gear. Very good brand.

    I have actually had more luck with Josco Brumby "Strip It" discs. They are blue in colour and are like Scotch Brite, but a bit stiffer with some sort of coating. I have used them quite a bit and had exceptional results. They have been much better for me than the flap discs. They leave a high quality surface. Excellent for welding and make really light work of removing paint and rust. I have also found that they do not wear much. At $10 from Bunnies I can't recommend highly them enough. I ended up getting them after trying to strip paint with wire wheels (Josco) on the grinder then flap discs (Josco and others). Both took quite a lot of time and did not leave the best surface finish. The "strip it" discs were much more efficient with less surface damage and a better finish.

    You can find info on them here: Josco | Brumby Strip-it Discs

    We used to call those "crumpets". From memory they were very good but would disintegrate fast if you caught a sharp edge. They have probably improved a bit over the years though.

    Anyone got any thing to say about smith and arrows flap disks?

    Crumpets hey? I purchased a box of the Smith and Arrows flap disks a while back. The last one I used a few weeks ago partially disintegrated when I caught the edge of some angle iron. I then moved to the trusty blue Josco and wondered why I ever bothered with the flap disk in the first place..
    I would say however that the Smith and Arrows disks are higher quality than their Ebay cousins (Patriot branded), which I also got a box of a while back..

    Smith and Arrow also have "poly strip" discs which are cheaper and I think last longer than the Josco ones

    The Strip-It style discs are the best thing for removing paint and rust, although they wear fairly fast around edges in my experience. That observation is probably amplified by the cost of the things...

    Flap discs however are excellent for grinding off edges/welds to a nice smooth blended finish - they tend to cut in hard on bits that are sticking up, whilst taking very little off larger flat surfaces. They do tend to clog pretty fast when used for paint removal though, and are much slower than the Strip-It style discs in that situation.

    Heavy duty wire wheels on an angle grinder can also do a decent job of removing paint and rust - slower than a Strip-It disc, faster than a flap disc, and last far far longer than both!

    All depends what exactly you're trying to achieve, I use all of the above dependent on what I'm working with at the time...
