Brush Research 09C28211 FLEX-HONE Cylinder Hone Surface Finishing Tool

The Brush Research 09C28211 is a FLEX-HONE® flexible cylinder honing tool from Brush Research Manufacturing (BRM), designed for internal bore surface finishing and deburring. Built on BRM's proven abrasive-globule technology, this tool delivers a controlled crosshatch finish and true plateau surface free of torn or folded metal — ideal for a wide range of precision bore finishing applications.

Key Features:

• Self-centering, self-aligning, and self-compensating — abrasive globules on independent flexible nylon filament suspension conform to the bore automatically
• Simultaneously finishes and deburrs in a single operation, reducing setup time and machining steps
• Produces an oil-retaining crosshatch pattern and plateau finish that promotes proper ring and seal seating
• Removes machining imperfections, glazing, and burrs with minimal material removal
• Compatible with virtually any rotating spindle — drill press, CNC machining center, or hand drill
• Manufactured in the USA by Brush Research Manufacturing, a trusted industry leader since 1958

BRM FLEX-HONE tools are widely used in automotive, hydraulic, pneumatic, and industrial machining applications where consistent, repeatable bore finishes are required. The flexible construction allows the tool to follow the bore centerline without the need for precise machine alignment, making it an efficient and cost-effective solution for both production and maintenance environments.
