For sale: 14 Industrial Diamonds for dressing various grinding wheels. 12 have never been used and 2 are used. These are mounted in 1/2" and 3/8" shafts. Most can be re-set when the current tip has been used. These are from the Precision shops I ran when I was a working "Youngster." I have a few I kept I'm using in my workshop with my bench grinders. Asking $165.00 for the lot of 14 diamonds. Pick up in Hereford AZ. Thanks.
