FLEX HONE GB31224 Cylinder Hone 3-1/2″ Max Bore Diameter, 240 Grit The Flex-Hone Tool is a resilient, flexible honing tool used to improve the internal surface finish while also being able to deburr a bore or cylinder. It is comprised of abrasive globules laminated onto the ends of flexible nylon filaments. Its unique construction allows the tool to be self-aligning, selfcentering and self-compensating for wear. The tool provides the benefit of removing loose, torn and folded metal and creating a substantially flat or plateau surface. An additional important application for the Flex-Hone Tool is burr removal from cross-drilled holes and slots. Features Versatile Abrasive Action: The FLEX HONE GB31224 features silicon carbide abrasive globules that create a soft cutting action. This allows for deburring cross-drilled holes, port radiusing, and edge blending while achieving a smooth honed finish. Its adaptability makes it suitable for various applications beyond just honing cylinders. Self-Centering Design for Consistent Results: This cylinder hone is equipped with independent suspension. This special feature ensures self-centering and self-alignment during honing. The self-centering design minimizes the risk of bore distortion and guarantees consistent results throughout the honing process. Easy to Use and Requires Minimal Setup: The FLEX HONE GB31224 is user-friendly and requires minimal preparation. It can be attached to a standard drill motor and used with light pressure to hone the cylinder bore. This simplicity makes it a great option for both professional and DIY applications.
