### ⭐⭐⭐⭐⭐ Cheap and effective
*by C***N on November 1, 2024*

It worked to hook my 1/2" drill to a masonry coring bit using the 5/8-11 thread. I would also think this would work for other tools that are used on common die grinders. It was easy to install, and easy to remove. Overall would recommend. It has a black coating that did not chip or peel during my testing.
