Sunnen Honing Mandrel 2H-P28-2375WG | 2.355 In. to 2.500 In. Bore Range | Orientation: Axial

A pair of Sunnen P28 two-stone honing mandrels, part number 2H-P28-2375WG, manufactured in St. Louis, Missouri, USA. Each mandrel body is stamped with the WG-D identifier and carries the 2H-P28-2375WG part number on the flat shank surface. The P28 series uses a keyed shank design for use with Sunnen vertical honing machines and is compatible with Sunnen P28 series stones, wedges, shoes, and truing sleeves. The WG designation corresponds to a bore sizing range of 2.355 in. to 2.500 in. (59.8 mm to 63.5 mm). The 2H prefix identifies this as a two-stone configuration with the H-series head length. Each mandrel features three slotted adjustment screws on the body face for stone and shoe positioning. The P28 mandrel platform is used for precision bore sizing and surface finishing in open, blind, slotted, and tandem-land bore configurations across automotive, heavy equipment, hydraulic, and general industrial applications. The current Sunnen catalog equivalent part number is 2HP282375WG. Both units are made in the USA. Stones, shoes, and truing sleeve are not included and are not visible in the photos.
