The FLEX HONE GB41812 is a 4-1/8" (105mm) flexible cylinder hone designed for finishing and deglazing block cylinders. Made with 120-grit silicon carbide, it delivers precision surface finishing and deburring, making it ideal for automotive, industrial, and marine applications.
Features:
Provides an optimal surface finish, reducing Ra, Rk, and Rpk values while maintaining Rvk and Vo volume for oil retention.
Deburrs cross-drilled holes efficiently, creating a smooth and radiused intersection.
Self-centering and self-aligning for easy use without complex setups.
Supports plateau finishing to enhance lubrication control and extend seal life.
Used in various applications, including automotive, aerospace, marine, and hydraulic systems.
