Sunnen External Honing Stones FD64AA75 FD64 Series, 2 Stones Per Box

The Sunnen FD64AA75 is a set of two external honing stones manufactured by Sunnen Products Company for use with Sunnen FD-series external hone bodies. External honing stones in this series are used for finishing outside diameters on precision machined components, correcting surface irregularities such as taper, out-of-round, barrel shape, and centerless grind patterns. The AA designation in the part number identifies an aluminum oxide abrasive with vitrified bond, consistent with Sunnen's conventional abrasive line for external honing applications. The 75 designation indicates the grit and hardness grade within Sunnen's coding system. This type of abrasive is suited for a wide range of materials including hardened steel, soft steel, and ferrous alloys. The FD64 body series is part of Sunnen's external hone tooling product line, designed for low-production, tool room, salvage, and maintenance applications. These stones are sold as a box of two and are intended to work in conjunction with compatible Sunnen FD-series hone bodies and guide shoes. Sunnen is a US-based manufacturer headquartered in St. Louis, Missouri, and is recognized as a leading supplier of precision honing systems and abrasives for industrial and automotive applications. The box shows the Sunnen Products Co. branding consistent with the company's legacy packaging.
