Brush Research P83132N Plateau Flex-Hone Ball Hone Cylinder Honing Tool

The Brush Research P83132N Plateau Flex-Hone® is a flexible cylinder honing tool engineered to produce a superior plateau finish on engine bores and other cylindrical surfaces. Designed and manufactured by Brush Research Manufacturing (BRM), this tool is ideal for engine rebuilders, machine shops, and performance enthusiasts who demand precise surface finishing results.

The Plateau Flex-Hone® uses BRM's exclusive ball-style abrasive globules mounted on flexible nylon filaments, allowing the tool to self-center within the bore and follow the cylinder's natural contour. This design produces a cross-hatch finish with oil-retaining valleys and a smooth, flat plateau surface — the ideal profile for modern piston ring seating and reduced break-in time.

Key Features:

• Produces a true plateau finish with consistent cross-hatch angle
• Self-centering, self-aligning flexible design conforms to bore geometry
• Reduces friction and promotes faster piston ring seating
• Compatible with standard electric drills and drill presses
• Suitable for use on cast iron, aluminum, and steel cylinder walls
• Removes glaze and light surface imperfections without aggressive material removal
• Durable nylon filament construction for long service life

The P83132N is part of BRM's trusted Flex-Hone® product family, backed by decades of engineering expertise in surface finishing technology. Use with BRM's recommended honing oil for best results.
