The jig assembly holds the drill bit at the select-
ed height and horizontal/vertical angles during
operation.
Refer to
Figure 2 and the descriptions below
to become familiar with the jig components and
controls.
Height Scale: Displays the correct setting for the
bit's diameter so that its center point is aligned
with the wheel center point.
Height Lock Lever: Secures the bit carrier at the
selected height and vertical angle.
Height Set Screw: Aligns the bit center point with
the wheel center point.
Flute Pin: Keeps the bit from rotating in the car-
rier from the rotational force of the wheel.
Tailstock: Keeps the bit from moving away from
the wheel during operation.
Angle Scale: Displays the combined angle of
both bit point angles that will be cut.
Bit Carrier: Keeps the bit steady with a V-type
trough configuration.
With the use of the pivot lever, the pivot base
moves the drill bit in a precise path across the
cutting edge of the grinding wheel.
The jig assembly and pivot base are mounted on
the carriage, which is moved toward or away from
the wheel with the use of the handwheel.
Refer to

become familiar with the pivot base and carriage
controls.
Stop Rod Lock Knob: Secures the stop rod in
place.
Carriage Handwheel: Moves the drill bit toward
or away from the grinding wheel.
Pivot Lever: Moves the drill bit across the cutting
edge of the wheel in a precise path.
