Brush Research 08A11471 Flex-Hone Flexible Cylinder Hone 8mm Bore

The Brush Research 08A11471 is a Flex-Hone® flexible cylinder hone designed for precision surface finishing, deburring, and cross-hatch plateau honing in small-bore applications. Engineered by Brush Research Manufacturing (BRM) — the original inventors of the Flex-Hone — this tool delivers consistent, repeatable results in bores as small as 8mm.

The Flex-Hone uses abrasive globules permanently laminated to flexible nylon filaments, allowing the tool to self-center and self-align within the bore. This design produces the ideal plateau finish required for proper oil retention and ring seal in engine cylinders, valve guides, and hydraulic components.

Key Features:

• Bore Size: 8mm (nominal)
• Flexible abrasive ball design self-centers and self-aligns in the bore
• Produces a controlled cross-hatch surface finish ideal for sealing and lubrication
• Removes burrs, sharp edges, and surface irregularities without aggressive material removal
• Compatible with standard drill motors and CNC equipment
• For use with honing oil or cutting fluid for best results
• Manufactured by Brush Research Manufacturing — the inventors of the Flex-Hone

The Brush Research 08A11471 is ideal for machinists, engine builders, and maintenance professionals requiring a reliable, easy-to-use finishing tool for small-diameter bores. Simply chuck the tool into a drill press or hand drill, apply honing fluid, and achieve a professional-grade surface finish in seconds.
