B. Insert the chuck into the sharpening port. While lightly pushing
in and down, rotate the chuck clockwise in half rotation incre-
ments. (See Picture #14) The chuck will move in and out and the
sharpening port will slightly swing during this process. Let the
cams on the chuck dictate the natural in and out sharpening mo-
tion.
NOTE: The sharpening port is swinging due to the cam on the
chuck riding against the cam follower bearings. DO NOT LIFT THE
CHUCK UP AS YOU ROTATE IT. The initial grinding occurs when
the “valley” of the feed cam rides against the in-feed cam bearing.
(See Picture #13) Once the grinding becomes quiet (sparks out)
the sharpening is complete. Inspect the drill point and if it does not
have adequate relief see the next paragraph. DO NOT REMOVE
THE DRILL FROM THE CHUCK IF THE POINT IS TO BE SPLIT.
About Relief Settings
After aligning and sharpening the drill bit, if the relief needs to be
increased or decreased, then the following procedure is required.
A. Rotate the alignment paddle from “0” to the “plus” side num-
bers of # 1. , # 2. or # 3. to increase the relief setting. The fur-
ther right the paddle is moved, the more relief the drill will have
after aligning and sharpening.
B. To decrease relief, move the paddle left to the “Minus” side at
the #1, #2 or #3 location. The further left the paddle is moved,
the less relief the drill will have after aligning and sharpening.
C. See Illustration 15
STEP 4: Splitting the drill point
You can split any drill point that the V390 is capable of
sharpening. See below “Point Split Port Adjustment” diagrams and
definition of a properly split drill point.
