Specialty Flex-Hones for Blending Chamfered Through Holes


Brush Research Mfg. Co. Inc., (Los Angeles, CA) has created a line of specialty Flex-Hones designed to blend and radius sharp edges and remove microburrs on chamfered holes eliminating stress risers caused by the chamfering operation.  Standard Flex-Hone tools are very effective on the interior corners (the intersection of the chamfer and the hole wall).  This new series of tools 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 allows the tool to pass through thin web sections and polish the chamfer on the back side as well.  The Flex-Hone 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.
