17. Rotate the carriage handwheel counterclock-
wise one increment of the scale shown in
Figure 32 to move the drill bit away.
The handwheel scale is in increments of
0.30mm or approximately 0.012", with one
full rotation moving the carriage 15mm or
approximately 0.600".
Note: Slightly backing the drill bit away from
the wheel will allow the first grinding passes
to take off any burrs or high spots.

Grinding wheels have the capability of
removing a lot of skin quickly. Keep a firm
grip on the drill bit in the jig and position
your hands safely away from the wheel dur-
ing operation.
18. Pull the pivot lever all the way back to move
the drill bit away from the grinding wheel,
then connect the machine to power, turn
it
ON, and wait for the wheel to reach full
speed.
19. Hold the drill bit firmly against the tailstock
and flute pin with your right hand.
20. To perform a grinding pass, move the pivot
lever with a moderate and steady motion to
pass the bit across the wheel's inside cutting
edge, then stop when you feel resistance
from the front stop rod.
21. Without moving your right hand, reverse the
motion of the pivot lever until the drill bit is
clear of the grinding wheel.
22. Turn the machine OFF and wait for the grind-
ing wheel to come to a complete stop.
23. Rotate the drill bit 180° in the bit carrier and
repeat Steps 18–22 to grind the opposite
side of the bit.
24. Rotate the carriage handwheel clockwise one
increment of the handwheel scale to move
the drill bit toward the grinding wheel 0.30
mm (or approximately 0.012"), then repeat
Steps 18–22 again.
25. Repeat Step 24 until you are satisfied with
cutting edges and point angles of the bit.
