The Flex Shaft tool is one of the most versatile tools a jeweler can have at his disposal. It's super handy because it's pedal operated, leaving you in complete control! As you can see in the photograph below, this tool can be used for many applications (not only metal work).
In the past, I had purchased a drill press to drill holes in my fused glass pieces, but now with my Foredom flex shaft, I no longer need the drill press for this; I can perform all of my work from my work station. This tool was the best purchase for my craft! I could not live without it!
