252 pieces in all. The sanding bands come in three sizes: 1/2″, 3/8,” and 1/4.” There are 80 pieces each of the three sizes. There are also 12 shank sanding drums in three diameters: 1/2″, 3/8,” and 1/4..
120 grit is the most common and standard size for sanding bands. They are used to smooth surfaces and curved edges, polish both soft and hard materials, like home improvement, art, and woodwork.
Drum mandrels with self-expanding rubber cushions make it easy to attach the sanding bands to the mandrel and get a better finish. If the sanding band comes loose from the mandrel while you’re using it, make sure the drum is screwed tight and wears close to the sleeve.
There may be flying grits when the sanding drum turns at high speed, so you should wear professional safety glasses to protect your eyes. The sanding drum will move faster on metal surfaces, so you should change the sleeves as soon as possible to get the best sanding results.
Bonus: It comes with a free plastic box, which makes it easy to store and pick up.
I wouldn’t buy these things again. I was sanding wood with them today, and almost all of them blew apart at the seams. None of them could last two minutes. They’re dangerous.
These are the best-priced rotary tool drum sanders that I could find on Amazon, so I bought them. To get this set, you’ll pay $9. They have a lot of grit and work well. I gave them three stars because of two things. The first reason is that the drum sanders don’t all fit on the mandrels that come with them. You have to test them to see which one fits best and then use that mandrel. The second thing I found out when I used these to change a polyurethane bumper. Because these things are so light, they easily break apart at high speeds. They tear right through the outside seams. You can use them at high speeds if you don’t put a lot of stress on them. I’ve used them to sand metal at both high and low speeds, and they work well for that. Again, you have to be careful with how much pressure you put on them. A lot of time, but I’ll look for other brands. If I can’t find any better deals, I might buy these again. They are good, but not great.
