I have over 60 various surface grinder stones. I have white, gray, clack, green and red. Many sizes and grits. I can provide a list if you are interested. Most are 1-1/4" center hole, but some are 1/2". I have pictured a few samples below. Most of them are dirty from laying around the shop, but still very usable. I am open to offers for one or all. Located in central Illinois. I can get good shipping rates if you need them shipped. marklynch.ak at gmail.com
