Automotive

Brush Research Manufacturing (BRM) provides flexible honing tools and industrial brushes to auto parts manufacturers, engine rebuilders, diesel mechanics, car and kart racers, hobbyists, and automotive restoration specialists. Available in numerous sizes, grits, and abrasive types, the Flex-Hone® tool is ideal for engine block honing, surface finishing, deburring, and cylinder deglazing. BRM also supplies a full line of automotive brushes, including high-quality NamPower™ abrasive brushes.

From brake drum makers to truck engine remanufacturers, automotive parts suppliers use machine-mounted Flex-Hone® tools for consistent, high-quality surface conditioning and deburring results. For any type and size of automotive cylinder, the Flex-Hone produces a unique crosshatch pattern for optimum lubrication. When used for cylinder deglazing, the Flex-Hone® provides for the proper seating and sealing of new piston rings in car engines. Often, hobbyists use the Flex-Hone with an electric drill.
