Brush Research HONE ENGINE CYLINDER FLEX 4-1/4IN. 180 GRIT

Features and Benefits:

For any type and size of cylinder; the FLEX-HONE process (Superfinishing) produces a controlled surface condition unobtainable by any other method. It involves finish; geometry and metallurgical structure. A high percentage plateau free of cut; torn and folded metal (with radiused ports).

A resilient; flexible; honing tool with a soft cutting action. The abrasive (points) globules each have independent suspension that assures the Flex-Hone to be self-centering; self-centering to the bore; and self-compensating for wear. Specifically; it is a low-temperature abrading process that exposes the undisturbed base metal structure to produce a longwearing surface. It is a method of developing a surface on a metal part which is optically smooth and metallurgically free of any fragmented; amorphous or smeared metal from previous operations. It is accomplished at a low pressure where the ""stones"" float. See and read the various booklets of actual tests covering almost every situation that will ensure a superior performance in situations depending on surface finish. The particular type of Flex-Hone crosshatch is extremely efficient in providing a multiplicity of oil grooves or valleys for oil retention as opposed to the often unidirectional or uneven valleys common to the conventional type rigid hone. A crosshatch that usually remains as the cylinder wall has been wear-reduced by the Flex-Hone.
