This professional set of PAUSNOP 514-9-21J Diamond Honing Stones is designed for precision cylinder honing using compatible Rottler honing systems.
Each stone measures 3" (76 mm) in length and features 1200 grit diamond abrasive. This super-fine abrasive is intended for the final polishing stage where maximum surface quality, exceptional bore geometry and the finest possible finish are required.
Under proper honing conditions these stones are capable of producing an expected surface finish of approximately 1–2 Ra microinches (0.025–0.05 μm).
Typical Surface Finish: Approximately 1–2 Ra microinches (0.025–0.05 μm), depending on cylinder material, machine condition, honing oil, pressure, spindle speed, stroke speed and operating parameters.
Duties & Taxes: Included in our shipping price (Delivered Duty Paid – DDP). You will not be charged additional customs duties, import taxes or brokerage fees upon delivery.
