The Surface Reconditioning Flexible Hone restores and conditions internal cylinder bore surfaces in engines. It consists of abrasive globules mounted on flexible filaments that conform to the bore geometry, allowing consistent contact across the entire surface. The hone removes glazing, light scoring, and residue buildup while producing a uniform crosshatch pattern for oil retention and piston ring seating.Attributes:• Provides controlled material removal.• Produces a uniform crosshatch pattern for oil retention.• Removes glazing and minor surface damage.• Lowered oil consumption, less friction, plateaued finish over 50 percent. • Suitable for engine bore size 101.6 mm (4 inch).Applications: The Surface Reconditioning Flexible Hone is used inside engine cylinder bores during maintenance or overhaul processes to restore the internal surface condition before reassembly.
