HD Block Cylinder Flex-Hone - 4-1/2" - 180 Grit - Brush Research

The Brush Research GBD4-1/2 HD Block Cylinder Flex-Hone is a professional-grade abrasive tool engineered for precise cylinder wall preparation in demanding automotive and industrial applications. This 4-1/2 inch, 180 grit silicon carbide Flex-Hone delivers a consistent plateau finish, essential for optimal piston ring seating, enhanced lubrication, and extended component lifespan.

Key Features

• Heavy-Duty Construction: Designed for rigorous use in engine block and industrial cylinder honing environments, this tool ensures exceptional durability and reliable performance for professional technicians. Heavy-duty Flex-Hones are commonly used for applications such as block cylinders, liners, stationary diesel engines, and oil and gas pipes.
• Self-Centering and Self-Aligning Design: The flexible, ball-style abrasive automatically centers and aligns within the bore, simplifying the honing process and effectively adapting to minor bore irregularities without special fixturing. This unique construction also makes the tool self-compensating for wear.
• 180 Grit Silicon Carbide Abrasive: Utilizes a 180 grit silicon carbide abrasive for efficient material removal during deglazing and resurfacing, producing a precise and uniform finish on cylinder walls. Silicon carbide is the recommended abrasive for most automotive engine applications.
• Optimal Cross-Hatch Pattern: Creates a consistent and effective cross-hatch pattern, which is crucial for superior oil retention, promoting proper piston ring break-in, and ensuring effective sealing.
• Enhanced Component Longevity: Facilitates superior piston ring sealing and optimal oil distribution, directly contributing to increased operational life and efficiency of cylinder components in rebuilt engines and hydraulic systems.

Applications

• Resurfacing and deglazing of engine cylinders during rebuilding and routine maintenance procedures.
• Achieving a precise surface finish in hydraulic, pneumatic, and various industrial cylinder applications where a controlled surface is critical.
• Preparing cylinder walls for improved piston ring seating and optimized performance in high-demand environments.
• Removing loose, torn, and folded metal, and deburring cross-drilled holes and slots.
