The Sunnen FD64AA73 is a two-piece set of external aluminum oxide honing stones in vitrified bond construction, part of Sunnen's FD64 tool series for external honing applications. External honing with Sunnen FD-series stones is used to finish and size the outer diameters of shafts, pins, and cylindrical workpieces on Sunnen horizontal honing machines equipped with compatible external hone bodies. The AA73 designation indicates aluminum oxide abrasive with vitrified bond in the 320-grit range, suited for precision finishing operations on ferrous and non-ferrous materials where a fine surface finish is required. This set contains two stones as indicated on the original factory packaging. Sunnen is an industry-leading manufacturer of honing abrasives and tooling based in St. Louis, Missouri, with products widely used in engine rebuilding, hydraulics, aerospace, and precision machining applications. FD64-series stones are compatible with Sunnen FD64 external hone bodies and are used in conjunction with matching FD64 guide shoes. This item is offered in its original factory box.
