USE/CARE OF HANDTOOLS & MEASURING TOOLS - OD1621 - LESSON 2/TASK 2
(c) Inspect the pipe cutter to make sure there are no nicks or
burrs in the cutting wheel.
Open the jaws of the cutter by turning the
handle counterclockwise.
(d) Position the cutter around the pipe at the marked point. Make
sure the cutting wheel is exactly on the mark and close the jaws of the
cutter lightly against the pipe by turning the cutter handle clockwise.
(e) After making contact, turn the cutter handle clockwise one-
fourth of a turn more. This will put a bite on the pipe.
(f) Grasp the cutter handle and rotate the cutter as a whole, one
complete revolution, swinging it around the pipe in the direction indicated
in figure 124 on the previous page.
(g) Turn the cutter handle clockwise one-fourth of a turn more to
take another bite on the pipe and rotate the cutter, as a whole, another
complete revolution. Keep the cutter perpendicular to the pipe at all times
or the wheel will not track properly.
(h) Repeat (g) above until pipe is cut.
Remove the shoulder on
the outside of the pipe with a file and the burr on the inside with a
reamer.
d. Use of Tube Cutters.
(1) Measurement.
Measure tubing as you would measure pipe.
(2) Cutting Tubing.
The procedure for using a tube cutter is the
same as for pipe cutters, except that for small diameters a vise is not
necessary.
Tubing is held in one hand and the cutter rotated with the
other. For large diameter tubing, using a vise is advisable. Be certain to
use soft jaws on the vise to prevent damage to the tubing. Use the reamer
blade, with which most tube cutters are equipped, to remove any burrs from
the inside diameter of the tube after it is cut.
e. Use of Flaring Tool.
(1) Single Flare.
With the die block clamp screw loose, inset the
tube in the corresponding size hole so that the tube extends approximately
165
