other hand to firmly grip the driver drill. Brace yourself for a torque reaction. Failure
to observe this caution may result in injury or lossing your balance and falling.

exposed. Remove punch form draw stud. Slide the die off the draw stud. To
remove the slug, turn over and tap lightly on a solid wooden object.
NOTE:
To avoid excessive wear and tear on the draw stud threads during punching,
center the pull rod accurately so that it does not rest against the metal edge of the
guide hole. Also, be sure that all points of the punch are in uniform contact with the
metal surface when starting to punch.
PUNCHING 3-1/2" AND 4" HOLES
