As the world’s foremost authority on honing, Sunnen has incorporated more than 90 years of research and development into a complete, top-quality line of honing abrasives.

We manufacture all of our abrasives to our own high standards, and then grade and qualify each stone to ensure the stones you buy today will perform exactly the same as the ones you bought last year or will buy next month.

Not only do we offer the industry’s largest variety of abrasive materials, bond types, grain sizes and stone configurations, we also have the largest staff of engineers and technical experts, continually working to advance the honing process. From aluminum oxide and silicon carbide conventional abrasives to diamond and cubic boron nitride (CBN) superabrasives, our honing stones deliver unparalleled quality, accuracy and performance. Regardless of the material being honed – including ordinary hardened steel and hard-to-hone materials like corrosion resistant (CRA) alloys and Inconel – you can depend on Sunnen honing abrasives to meet your needs.
