Adapter Extension for extending the length of our rotation files by almost 4 inches. Fits all our rotating tools from A-0001 through A-0008. It can be used in conjunction with FG-2VX-50 / A-0107 and FCD-6X-51 / A-0104. Useful for hard to reach places. It may add some vibration to the tool as is the nature with most extensions. Should be used only when necessary and removed for jobs where it is not required.
