Block Cylinder Flex-Hone - 4-5/8 In - 120 S/C - Brush Research

The Brush Research GB458-120SC Block Cylinder Flex-Hone is engineered for professional technicians and mechanics requiring a precise and consistent finish on cylinder walls. This resilient and flexible honing tool is designed to deliver a soft cutting action, making it ideal for engine rebuilds, compressor maintenance, and various industrial applications where surface integrity is paramount.

Key Features

• Self-Centering Action: Abrasive globules with independent suspension ensure the tool is self-centering within the bore, promoting uniform material removal.
• Bore Alignment: Self-aligning capabilities allow the Flex-Hone to conform precisely to the cylinder's contours, correcting minor imperfections without altering bore geometry.
• Wear Compensation: The design self-compensates for wear, maintaining consistent honing pressure and effectiveness throughout the tool's lifespan.
• Soft Cutting Action: The flexible construction and silicon carbide abrasive provide a gentle yet effective honing process, minimizing the risk of damage to critical cylinder surfaces.
• Optimal Finish: Creates a Plateau finish, which is crucial for improved oil retention and ring seating in high-performance engines and industrial compressors.
