Sunnen Grit Cylinder Honing Stone Set

Sunnen cylinder honing stone sets are replacement abrasive stones for AN-style portable cylinder hones. Engine builders and machine shops use them for cylinder honing, deglazing, and final surface finishing on engine blocks and sleeves. Each stone set is made by Sunnen, a long-established name in honing technology, and is available in a range of grits so you can match the stone to the job.

Key Features:

• Genuine Sunnen abrasive stones with integral holders for secure, consistent mounting
• Aluminum wipers in the set help support the hone and keep it centered in the bore
• Different grits cover everything from fast stock removal to fine finishing, which lets you control cylinder wall surface finish
• Designed for use with Sunnen AN-series portable cylinder hones and compatible AN-style hone bodies
• Versions are available for standard, short, and blind bores and for hard sleeve applications
• Intended for use with honing oil

Choose the grit and bore range that suit your application. Coarser grits remove material and correct the bore. Finer grits produce the final finish needed for proper piston ring seating. Reliable cutting performance and a predictable finish make these stones a dependable choice for engine rebuilding and cylinder service.
