    I've been using these Max Flex disc's to clean up aluminum castings.
    They have 24 and 36 grit depressed center disc's for angle grinders.
    There is another called Aluminator but I haven't tried it.

    I occasionally use flap discs and cutoff wheels designed for aluminum, but most of my parts are used as-is or destined for the lathe/mill so I don't use them often. I haven't tried a lot of brands, but Benchmark Abrasives have thus far been the best I have found.

    We usually use tiger disc....flap disc. I also have found that using Johnson's stick wax makes grinding aluminum so much easier with whatever you use!

    I found their aluminum cut off disc's on Amazon. Ordered a pack of 25.
    Sometimes I get a little uptight de-sprueing an odd shaped one on my table saw, maybe this will relieve some of the angst. :)
    Thanks

    Try the wax with the cutoff wheels! Trust me you will see a major difference!

    I've used Pam, WD40 and wax on the table saw blade and the belt sander.
    My problem with using them is a lot of my castings get powder coated and it causes more work cleaning them.
    I can use it to de-sprue though.
    Thanks Billy
