For sale I have a Delta 8" Aluminum Oxide 60 Grit Fine Grinding Wheel- part #23-269.  It is 1" thick and has a 5/8" arbor.  I see no signs of use on the grinding edge- no grooves or rounded edges on the wheel.  It does have a round mark on the label, which makes me think it was previously mounted on a grinder.  But, like I said, I see no signs of use.

Shipping is FREE.  Will ship next business day after payment.
