Brush Research GBD61224 Flex-Hone Engine Cylinder Honing Tool 6-1/2" 240 Grit Silicon Carbide

The Brush Research Flex-Hone® Tool is a flexible honing tool designed for precision surface finishing, deburring, and plateau finishing in engine cylinders and bores ranging from 6 to 6-1/2 inches in diameter. This heavy-duty model features silicon carbide abrasives with 240 grit for fine finishing applications, measuring 6-1/2 inches in diameter by 17-1/2 inches in length.

Key Features:

• Silicon carbide abrasive material with 240 grit for superior surface finishing
• Self-centering and self-aligning design eliminates need for rigid setups
• Flexible construction conforms to bore geometry for consistent results
• Navy blue end marking color for easy grit identification
• ISO 9001 compliant manufacturing standards
• Suitable for bore capacities from 6 to 6-1/2 inches

Applications and Benefits:

• Surface Finishing: Reduces Ra, Rk, and Rpk surface roughness values while maintaining Rvk oil retention characteristics, creating an optimal surface for ring seating and seal longevity
• Deburring: Efficiently removes burrs from cross-drilled holes, leaving clean, radiused intersections without expensive secondary operations
• Plateau Finishing: Eliminates peaks from prior machining operations to create a flat plateau surface with crosshatch pattern that promotes proper lubrication, reduces seal wear, and minimizes fluid seepage
• Adhesive Bonding Prep: Creates controlled surface roughness for improved bonding integrity in assembly applications

Ideal for automotive engine rebuilding, aerospace manufacturing, marine applications, hydraulic cylinder repair, firearms manufacturing, and general industrial machining operations. The Flex-Hone can be used in-machine or as an offline secondary operation with standard drill motors or machining centers.
