12MM 240AO FLEX HONE - Brush Research

The Brush Research 12MM 240AO FLEX HONE (Model: BC12M240AO) is a professional-grade flexible cylinder hone engineered for superior surface finishing and deburring of small-diameter bores. Designed for professional technicians and mechanics, this tool effectively removes cut, torn, and folded metal to create an optimal plateau finish that enhances component performance and longevity. Its unique design ensures consistent results, making it an essential addition to any automotive or industrial workshop.

Key Features

• Precision Abrasive: Features 240 grit Aluminum Oxide (AO) abrasive globules, ideal for finishing aluminum, brass, bronze, softer non-ferrous materials, and for deglazing Nikasil cylinders.
• Flexible and Adaptable: The resilient, flexible honing tool is self-centering, self-aligning, and self-compensating for wear, simplifying operation and eliminating the need for elaborate setups or special training.
• Optimal Surface Finish: Creates a consistent oil-holding crosshatch pattern and a true plateau finish, promoting rapid piston ring seating, improved oil retention, and reduced friction.
• Durable Construction: Abrasive globules are laminated onto the ends of flexible nylon filaments, ensuring a long-lasting and effective tool for demanding professional applications.
• Versatile Tool Compatibility: Can be efficiently used with various rotating spindles, including handheld drills, drill presses, or CNC machines.

Applications

The 12MM 240AO FLEX HONE is suitable for a wide range of automotive and industrial applications where precision surface finishing and deburring are critical. It is commonly used for deglazing cylinder walls in engine rebuilding, preparing new or turned brake rotors for instant pad seating, and finishing hydraulic and pneumatic cylinders. This hone is also effective for deburring cross-drilled holes, port radiusing, and edge blending in valve bodies, brake master cylinders, wheel cylinders, and other components.
