Included a pair of scrapers, a few sizes of wood and bimetal blades, a circular drywall blade, a hook and loop sanding triangle with a small number of sandpaper sheets of various grits, and a pair of what I think are carbide grinding attachments.
I was working with a cast iron frying pan, trying to get the lacquer off of it and grind it back to bare metal so I could flatten and recondition it. I tried the grinding bit, scraper, and sandpaper attachments, and they really didn't make much of a dent. The scraper was unable to remove the patina; the grinder did scratch the iron surface, but didn't help plane it out at all; the sandpaper had no effect whatsoever.
I wasn't surprised about the sandpaper. I figured the scraper would do fine on what's effectively burned on cooking oil, but it did practically nothing. The grinding disc seemed pretty mediocre; I can't think of an application that I would use it for.
Overall I am still reasonably happy with the purchase, because it gave me a bunch of options at a very low cost. It's an entry point, and I can replace the individual bits as they wear out with something better. The cast iron pan was a bit of a hard target to start with; will be interesting to see how the wood and metal cutters play out. The build quality on those is visually inferior to the sample bit provided with the Makita multitool I bought, though, so I'm not holding out a whole lot of hope.
