Setting The Groove Diameter For Copper
Tubing
When using the 975 Combo Roll Groover for copper tube,
the groove depth gauge on the groover cannot be used. It
will give incorrect groove diameters.
1. Turn the feedscrew clockwise to bring the groove roll
down in contact with the pipe outside diameter, then turn
the feedscrew one quarter additional turn. The adjust-
ing screw may need to be loosened (turned counter-
clockwise) to allow the groove roll to contact pipe. The
pipe and roll groover should be se cure to each other at
this point.
2. Make sure the groove depth
gauge is in the grooving po -
sition.
(Figure 5)
3. Turn the adjusting screw until it
is flush with the top plate of
the groover.
4. Find the diameter and type of
pipe to be grooved on Table A
and back the adjusting screw
off the top plate the corre-
sponding number of turns. For example, for 4" Sch. L
copper, back the adjustment screw 1

turns.
5.
Go to step 4 of “Setting/Measuring The Groove Dia -
meter” in the 975 Combo Groover operator’s manual. In
step 6 use the Copper Roll Groove Specifications.
