QUICK OPERATING STEPS
Models 500SP & 750SP
A. Setting for split point style
(full instructions page 4)
1. Determine the point angle of your drill by placing the drill point in the
point angle gauges. See A-1
2. Insert a chuck (without drill) into the sharpening tube
and pull the
loop handle out. Move point angle indicator to the setting needed (118°
or 135°). Make sure the loop seats properly. See A-2
3. Pull the alignment tube
handle slightly away from the housing and
move to the (Split Point) setting. See A-3
B. Aligning the drill bit
(full instructions page 4 and figure 9)
1. Insert the drill loosely into the chuck. Tighten the chuck knob clock-
wise, then loosen it so the metal chuck jaws are just loose enough for
the drill bit to slide in and out.
2. Align the flat on the chuck with the flat in the alignment tube
.
See B-1
3. Push the paddle
to open the blue spring steel pawls. See A-3. Push
chuck and drill assembly into alignment
tube so that the flat on the
chuck is entirely hidden. See B-2
4. Push the drill in to the drill stop. Release the paddle and rotate the drill
by the shank until the pawls grip inside the drill flutes. Keep the drill bit
pushed to the drill stop and turn the chuck knob clockwise to tighten the
jaws onto the drill bit. Push the paddle
back and remove the chucked
drill (see Figures 8 and 24 for correct alignment and terminology).
C. Sharpening the drill bit point
(full instructions page 5)
1. Turn the switch below the sharpening tube
on. Position the sharpen-
er so that you are looking at it from the perspective shown in C-1. Insert
the chuck in the tube
.
2. Rotate the chuck clockwise, in half rotation increments, 12 to 20 times
(on a medium size drill bit 1/4” to 3/8” ) in the sharpening tube
. It
is important to keep consistent pressure going INTO the tube
. Let the
cam dictate the natural in and out sharpening motion. The sharpening
will occur in the low part of the chuck cam. Do not push the chuck
down to the base. See C-2
D. Splitting the drill point
(full instructions page 6)
1. Move the chucked drill to the point splitting tube
and again
match the flats on the chuck with the flats in the tube
. Insert the
chucked drill until the flats are touching and the chuck does not
rotate.
2. Slowly pull the chuck forward giving the drill bit one or two short
”pecks” on the wheel. Repeat untill the split is to the middle of the
drill point. To avoid over-splitting inspect the drill point periodicaly.
See D-1
3. Pull the chuck out of the point split tube just far enough to rotate the
chuck 180°. Repeat steps 1 and 2 above.
