I have 3 grinding wheels for sale that are 10x1x3 (10 inch diameter, 1 inch wide, 3 inch through hole). The numbers on the wheels (all 3 are the same) are CSW-22650A and PA60-IV which means they are pink aluminum oxide, 60 grit, hardness of I, and they are vitrified. They are new, never used and ring when struck with my finger which means they are not cracked. They can operate at a maximum RPM of 3,245. Asking $40 each, cash. I travel between everett, puyallup, and the olympic peninsula so if you're interested and anywhere near that route I may be able to meet you. Email me or call/text me if you're interested. Thanks.
