HD Block Cylinder Flex-Hone - 3-1/2" 180 Grit - Brush Research

The Brush Research GBD3-1/2 3-1/2 Inch 180 Grit HD Block Cylinder Flex-Hone is a professional-grade honing tool engineered for precision cylinder bore resurfacing in automotive and industrial applications. This resilient, flexible hone provides a controlled, soft cutting action, making it an essential tool for technicians requiring a consistent and refined surface finish.

Key Features

• Flexible and Resilient Design: Conforms to bore surfaces for thorough and consistent honing.
• Independent Abrasive Suspension: Each abrasive globule moves independently, ensuring the tool is self-centering, self-aligning to the bore, and self-compensating for wear during operation.
• 180 Grit Silicon Carbide Abrasive: Delivers a specific finish ideal for preparing cylinder walls for optimal ring seating and oil retention.
• Heavy-Duty Construction: Built for durability and sustained performance in demanding workshop environments.
• Soft Cutting Action: Achieves a plateau finish without removing excessive material or altering bore geometry.

Applications

• Cylinder Bore Resurfacing: Efficiently restores cylinder bores to original specifications, preparing them for new piston rings.
• Removes Imperfections: Effectively eliminates scuffing, scoring, and tapers within cylinder walls, improving overall bore condition.
• Enhances Ring Seal and Compression: Creates an ideal cross-hatch pattern for rapid ring seating, leading to improved engine compression and performance.
• Engine Rebuilds and Maintenance: A critical tool for achieving a professional-grade finish during engine overhaul procedures.
