Sunnen KKN742A Cylinder Honing Tool Assembly Kit

Sunnen KKN742A Cylinder Honing Tool Assembly Kit is a Sunnen‑manufactured collection designed to configure a cylinder honing tool for bore finishing. The kit is part of Sunnen's KKN family of tooling, engineered for stable, repeatable honing results when paired with compatible Sunnen heads and fixtures. This assembly kit provides the essential components to configure a honing setup for cylindrical bores, enabling precise bore size control and consistent surface finish in engines and similar equipment. Typical applications include preparing worn or oversized bores for subsequent finishing steps in automotive and industrial engine work, reconditioning cylinders, and achieving uniform cross‑sectional bore geometry. Because it is an assembly kit rather than a complete honing head, it relies on compatibility with the Sunnen tooling ecosystem to ensure proper alignment, rigidity, and repeatable results across multiple bores. For exact contents, bore size ranges, and required companion components, consult Sunnen's official documentation for the KKN742A model, since contents can vary by configuration.
