Hex stem unthreads
KARL HORTIEN•March 22, 2015
Hex stem unthreads while trying to remove bit. Makes no sense why it's not permanently attached.

Works very well.
Despite the picture...
Matt Brady•January 2, 2014
Despite the picture seeming to show this is not a 1/4" hex mount chuck, it actually is, which is precisely what I wanted to convert an impact driver I have into a drill. Seems to be of excellent build quality. However it does wobble around a bit in my driver, so I think I will machine a spacer to make it fit more tightly around the collet.

Appears to e perfectly adequate. Good for convertibpng 1/4 inch hex to drill chuck. These are handy adapters to have for conversion purposes.
