Sunnen L10J65-280 Silicon Carbide Honing Stone

Sunnen L10J65-280 Silicon Carbide Honing Stone is a vitrified-bond honing stone designed for Sunnen honing equipment, delivering precise bore sizing and a smooth finish in metal bores. This 280-grit silicon carbide stone belongs to the L10 family, offering a clean cutting action and consistent wear to help you achieve tight tolerances in bores and other cylindrical metal components. The stone’s vitrified bond provides a rigid, heat-resistant matrix that maintains shape under honing pressure, while the silicon carbide abrasive yields a fine, uniform finish appropriate for finishing operations following rough stock removal. Intended for use with Sunnen honing heads and adapters, the L10J65-280 is selected when a mid-fine 280-grit finish is desired, balancing material removal with surface quality. Sunnen describes L10 abrasives as precision honing stones designed for accurate bore sizing and superior surface finishing, available in silicon carbide (like this L10J65-280) among other materials. The L10J65-280 continues Sunnen’s tradition of reliable, consistent honing performance, with standard compatibility across Sunnen’s L10-series stone selectors for general-purpose silicon carbide finishing in hardened steels and similar bore materials.
