6 Inch Bench Grinder Polishing Wheel, 320 Grit Tight Weave Tough Polishing Burnishing Wheel, Great for Refurbishing Golf Clubs Metal Copper, Perfect Size 1" Thickness for 0.8" Arbor(Red)

I just got these 2 discs and some basic cheap compound blocks. Started with the coarse, then medium and then fine. I haven’t ever used a bench grinder for this before so I can’t review the time frame it took, but, can’t be mad at the results.

I have an old set of golf clubs that need polishing, so I thought these wheels might work. I didn't see that there was any need for polishing cream, so I just spun the wheel dry and it worked! It leaves most all steel surfaces - a 9 iron to a hammerhead - it leaves a smoothly textured surface that is not very different than it was before "polishing." This wheel will NOT give you a mirror finish, but it will get you well on the way to it.

The 320 grit seems accurate, they work pretty but I was very disappointed to see how quickly they wear out to nothing. I used them for about 20 mins yesterday on a few aluminum parts and I totally used up one disc. They make a lot of dust when they break down.Good discs but don’t expect them to last long at all

I use these to buff aluminum and other metal and they do a decent job. They wear out fairly quickly so it’s good that they aren’t priced too high.

I use the wheels on my bench grinder to remove surface rust and discoloration on raw metal pieces and parts. They are a little bit aggressive and will change the surface of the metal but that’s to be expected. I’m not sure how long they’ll last but I haven’t worn them out yet. 5 stars from me!

The hole for the mandrel is 20mm or 5/4ths in. I can't find any bushings that adapt 20mm to 1/2". Pretty useless if they won't fit a 1/2" grinder shaft.

Basically a big scotch brite pad, which is what I was looking for. Used off & on for almost two months and it's performing exactly as I hoped. I expect it to last a reasonable amount of time.

These are nice scotchbrite wheels.They worked perfectly buffing out some rust and discoloration I had on tools.They appear to be wearing a little faster than what I am used to, but have no good way to measure .If you need one, shop a bit, but these work great.

Not been able to use as Not been able to fit to my standard bench grinder. The cardboard centre doesn’t fit on my grinder without an extension. This wasn’t made clear on the listing. Not happy ☹️
