The super abrasive stone, also known as a honing stick, described here is specifically designed for Sunnen honing machines. The honing equipment has different series of honing stones that can finish different types of bores with different bore diameters. For example, the Y series is mainly used to bore holes with a keyway.
If our diamond or CBN honing stones can’t be matched with your Sunnen honing equipment in size and bore diameters, please let us know. As a professional honing tool supplier, we can customize suitable products for you. In addition, we can offer honing stones and bore honing tools for Sunnen machines and other brand name honing equipment. For specific information, please check out “other honing stone.”
