2-1/2 inch 180-grit Flex-Hone for small engines with a steel/cast bore. This is a very popular hone for the piston ring set used in kart racing engines. Hone can be used in many other applications with a bore range of 2.50 +/- .100.
These hones remove minimal amounts of material and are used as final cylinder finish hones. Hones can be used as a cylinder prep (deglaze finish) during ring replacement. Hones are very simple to use and self-centering during operation.
Please feel free to contact us regarding the correct product and size for your application.
