The Brush Research BRM-BC12M18 Flex-Hone is a 12mm bore finishing tool featuring 180-grit silicon carbide abrasive globules mounted on flexible filaments. Designed for deburring, surface finishing, and edge blending in bores and cylinders, the flexible design allows the tool to self-center and conform to the bore geometry for consistent results.
Ideal for use in automotive, industrial, and MRO applications, this Flex-Hone produces a controlled cross-hatch finish that improves oil retention and promotes proper break-in of cylinder walls and similar bore surfaces.
