The new line of specialty Flex-Hones are designed to blend and radius sharp edges and remove micro burrs on chamfered holes to eliminate stress risers caused by the chamfering operation. Standard Flex-Hone tools are said to be effective on the interior corners (the intersection of the chamfer and the hole wall). The tool series is more flexible and designed to polish and radius the outer corners (the intersection of the chamfer and flange face) as well as the inner corners and hole. The increased flexibility enables the tool to pass through thin web sections and polish the chamfer on the back side as well. The tool eliminates hand finishing operations and produces consistent finishes from hole to hole, part to part. Available in a variety of grit sizes and abrasive types, it is suitable for finishing titanium, Inconel, super CVM and nickel-based stainless steel alloys.
