When conventional honing abrasives (non-diamond) are needed, Sunnen can supply virtually any combination of abrasives material, bond type, grain size and stone configuration you need. From aluminum oxide to silicon carbide, 36 to 1200 grit and a variety of bond materials and stone dimensions, our abrasives will help keep your honing operations running smoothly and efficiently.

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 and tomorrow are always consistent.

We also offer Genuine Sunnen Abrasives for operations using Barnes, Micromatic, Jones & Shipman, Gehring, Nagel, OTW and other honing equipment. This includes unmounted stick abrasives as well as mounted abrasives compatible with non-Sunnen equipment, in a variety of grit sizes, abrasives types and dimensions. Before settling for sub-par performance, find out how Sunnen abrasives can improve your honing operations.
