Sunnen Portable Hones are fast and efficient for all kinds of bore-sizing work. They can be run in an electric drill, air drill, drill press, or honing rig and are capable of honing open, shouldered, blind, keyway, splined, tandem, or rifled bores to a uniform surface finish of .08-1.5 micrometer Ra (3-60 micro inches Ra) in aluminum, welded, drawn or hardened steel, brass, ceramic, carbide, etc.
Sunnen Portable hones can correct undersize, taper, out-of-round, barrel or bellmouth shape and misalignment to tolerances of ,013mm (.0005") in diameters from 31,8-914mm (1.250"-36"). Larger sizes up to 1524mm (60") are available on special order, ideal for honing parts too big or awkward to bring to a machine tool.
