Selecting Tool Diameter
Tool diameter is determined by the nominal bore size in which the tool is to operate. The Flex-Hone® tool is always produced and used in an oversized condition. The degree of oversize creates a soft cutting action. For example, a 1" Flex-Hone size is ordered if a 1" bore is to be finished and the tool is provided oversized. If the bore size is between standard Flex-Hone sizes, the next larger standard Flex-Hone should be selected. For instance, if the nominal bore is 1.093", then the 1-1/8" Flex-Hone is ordered.

Selecting Diamond MESH
Diamond abrasive is supplied and rated using a MESH scale, not a grit scale. As such the numbers do not directly equate to the grit scale rating of our other abrasives. 170/200 diamond is approximately equal to 180 grit capable of producing finishes in the range of Ra 30-40 (.7 - 1.0 Micrometer). 800 mesh is approximately equal to 400 grit capable of producing finishes in the range of Ra 10-20 (.3 - .6 Micrometer). 2500 mesh is approximately equal to 800 grit capable of producing finishes in the range of Ra 3-10 (.05 - .2 Micrometer).
