The Brush Research Flex-Hone BC for 9mm (.354") bores uses 120-grit silicon carbide abrasive globules to produce a controlled crosshatch finish that reduces friction and improves oil retention in firearm cylinders and chambers. Its flexible ball-style construction allows the tool to self-center and conform to the bore for consistent, even material removal.
Ideal for gunsmiths and firearm enthusiasts performing chamber polishing, throat finishing, or general bore surface improvement, this hone is compatible with standard drill motors and rotating tools for quick, repeatable results.
