Rocaris 50 Pcs Abrasive Buffing Wheels, 1 inch Abrasive Buffing Polishing Wheels Burr for Rotary Tools-1/8(3mm) Shank, 120Grit, 180Grit, 320Grit, 400Grit, 600Grit

I use these for polishing challenge coins done using a fiber optic laser. These are a MUST for anyone doing polishing. You will go through them quickly so buy the 300 size bag. Put them in a Dremel and spend about one minute with each grit and you will be amazed at the result. Want a higher quality finish? Get some one inch cotton buffs for the Dremel and some metal polish for a really high luster shine. I’ve gone through two 300 unit bags of these dang things in the last 7-8 months. I only wish I could buy the “gold” 100-ish grit ones separately as I go through more of those than any of the others. Oh well….

Very practical

They will get your job done. Brass and steel ones clean well but don't last very long. Make sure you wear your safety glasses as the little wires fall out during use. Overall for the price they're not bad, just not very durable. I would buy them again for the small project I needed them for.

The media could not be loaded. I love the versatility of these polishing/stripping wheels. The quality to these are great if you’re not putting a lot of pressure on them. Let them do all the work and they’ll last you a long time during your work. They are not replaceable as they are on the Dremel where you can remove the screw and switch out the buffing wheel, so once they are used up, they are finished. The cleaning power or power for removing material on these is great. Offering you four types of grit to the wheels make your job a lot easier and faster. They fit perfect on a Dremel or any rotating tool similar to that and are super easy to swap out.

Normally in polishing your shaping comes first. Once the surface is shaped and flat ie smooth then you can start working your way though the grits of sand paper removing any Mill marks or sanding of the previous grit. these make quick work of working your way though the grits to get to that dull shine with the grey pad.Subjective Cons:(1) The brown pad (or rough grit) wears out the quickest.(2) Although these are small they are not small enough for the tightest of areas.(3) Will heat up your electric rotary tool as these are fun to use.(4) Just like any other rotary cutting tool these will catch corners and force your tool in the wrong directionPros:(1) These are much easier to use then sand paper even on larger surfaces.(2)Even though these do ware out they do a lot of work before they are unusable.(3) The low grit Brown (roughest) pad will not shape (remove surface metal) but will follow the current shape rounding edges slightly.I suggest getting 2 packs of these if your going to be using these for more then one small project. I'm rebuilding a motor with a ton of parts to clean and polish. I have yet to get though the rough fast wearing pad yet but getting down there.Clean oils and grease off the surfaces first as these will smear it across your surface. Unless your oil,wet sanding.

I used them to remove rust coding from brake rotors.

Works with a Drermel if you get a collet that fits. These are definitely a disposable like sand paper, work brilliantly for me making silver jewelry. Lots for the price, I'll buy more! Use with eye protection as the soft material does fly off. Love em!

These are satisfactory for small applications, like creating a finish on a 3D print, and they don't remove much material. However, they get used up very quickly and the shaft is too short for some prints.
