NORTON SAINT-GOBAIN Abrasives 85970 Aluminum Oxide, India Single Grit Benchstone (IM9), 11-1/2" x 2-1/2" x 1/2", Replacement Stone For IM313 Oilstone System

I thought it came with the case shown. Great product used them for 60 years.

Items a great stone, especially when mounted in the Norton three-stone system.

Taking one star away for inaccurate photos. As far as quality of stone it is an excellent size and cuts beautifully. 5 stars for product functionality. Can't go wrong with this stone

Awesome stone. To bad Amazon sucks and doesn't listen to its customers.

Second one we buy at the restaurant after 3 years. Great quality. If only a "please don't ship it with USPS" filter could be chosen, the delivery will be better.

This is a good bench stone .

What I expected, wanted and ordered. First shipment was wrong. Product was fine. Return could have been smoother.

Works good for Cleaning Heads and Blocks on Diesel engines just spray some wd on it and use it to ckeep the surface flat while cleaning gasket rements and grime off.
