Quill Stop, X3 and SX3 Mills

The Quill Stop provides a quick and accurate way to set the quill depth of cut. It is great for drilling multiple holes to the same depth. The Quill Stop is also very handy in performing single or repeated chamfering of parts. To set up the chamfer the first time on a part, turn the mill off and simply lower the cutter to the top of the part, lock the fine feed knob, and back-off one full turn (turn the Button Nut clockwise as viewed from the top). Then start the mill and turn the Button Nut on the Quill Stop counter clockwise in small increments until the cutter contacts the part. Then continue turning the Button Nut counterclockwise and alternately lowering the quill until the desired chamfer is achieved.

The Quill Stop works equally well performing inside chamfers using typical chamfering mills, and outside chamfers using, for example, a hollow mill.

Requires a slight modification to the mill (drill & tap 2, 1/4-20 holes in the side of the machine head).

This quills stop works well on the Grizzly G0619 and G0463 mills.
