Block Cylinder Flex-Hone - 3-1/2 In - 240 S/C - Brush Research

The Brush Research GB312-240 Block Cylinder Flex-Hone is a professional-grade abrasive tool engineered for precision finishing of cylinder bores in diverse automotive and industrial applications. Featuring 240 grit silicon carbide abrasive globules and a 3-1/2 inch nominal diameter, this Flex-Hone delivers a controlled, resilient honing action crucial for optimal engine performance and extended component longevity. It creates a superior plateau surface finish, preparing cylinder walls for proper oil retention and efficient piston ring seating.

Key Features

• Self-Centering and Self-Aligning: Equipped with independently suspended abrasive globules, the Flex-Hone automatically centers itself within the bore and aligns with its axis, ensuring uniform material removal and consistent results.
• Consistent Honing Action: The tool's flexible design allows it to compensate for wear and adapt to minor bore variations, providing a consistent and repeatable cross-hatch pattern throughout the cylinder bore.
• Premium Silicon Carbide Abrasive: The 240 grit silicon carbide abrasive offers a controlled cutting action, creating an ideal plateau finish that reduces friction and extends the operational life of engine components.
• Professional-Grade Construction: Manufactured by Brush Research, this tool is built for durability and reliable performance, designed to withstand the rigors of demanding workshop and industrial environments.
• Optimal Bore Preparation: Engineered to deliver a precise surface finish that promotes effective oil retention, reduces break-in time, and enhances the sealing properties of piston rings, ensuring peak operational efficiency.

Applications

The Brush Research GB312-240 Block Cylinder Flex-Hone is an indispensable tool for professional mechanics and industrial technicians. It is ideally suited for honing cylinder bores in internal combustion engines (both gasoline and diesel), air compressors, hydraulic cylinders, and various other industrial machinery. This tool is crucial for rebuilding engines and components where a controlled, high-quality surface finish is required to ensure peak operational efficiency and durability.
