Lock and loosen the HiTorque bench mill quill without the use of a hex wrench by adding a knob to make the process quick and easy. Custom made by Priest Tools, this upgraded version of the Quill Lock Knob (P/N 5875) is constructed of steel and has a 2" knurled surface for a sure grip and ease of use.

Simply remove the factory screw and replace with this threaded knob. The threading is cut for an exact fit so there is no modification necessary.
