We save every cut off wheel and roloc disc and keep track of them to charge them back to the customer. So I want to be sure with those the customer is getting their monies worth with those as well.

I buy ours from McMaster carr. Have it the next day and you can get any quanities and sizes.

I have liked the 3m green corps cut off discs the best, they cost a ton but seem to last forever :)

My part time job buys the really cheap roloc discs and I literally went through 5 of them cleaning up some rims where you normally only use 1 for a set of rims, I was very surprised at how quickly they would just burn up. I only use 3m at my full time job and they seem to last quite a while.

I have been loving the flap discs also:yes:

We have pretty good luck with Klingspor.com products
a little more cost retail (shops can get a 30% discount) but they last
I love the cut off wheels, they last, cut well & don't hang up or break.
