The Sunnen 2H-P28-2500WG is a two-stone bore honing mandrel manufactured in St. Louis, Missouri, USA, and designed for use with Sunnen horizontal honing machines. The WG stone designation covers a bore diameter range of 2.480 in. to 2.625 in. (62.99 mm to 66.68 mm), making this mandrel suitable for finish honing bores in that size range. The 2H prefix indicates a two-stone configuration, and the assembly features the WS-D wedge and stone holder sections visible on the body. The mandrel body is constructed of hardened steel and interfaces with the Sunnen machine via a 45mm shank, approximately 12 in. in overall length. The P28 series mandrel is a long-running Sunnen platform used across a wide range of engine rebuilding, hydraulic component, and general bore finishing applications. Part number 2H-P28-2500WG is the OEM designation used consistently in the US surplus and industrial tooling market. Made in the USA.
