975 Combo Roll Groover
• Clear, level, stable and dry location with adequate
space for all of the equipment and the operator.
2. Clean up the work area prior to setting up any equip-
ment. Always wipe up any oil that may be present.
3. Inspect the pipe to be grooved and confirm that the
975 Combo Roll Groover is the correct tool for the job.
The 975 Combo Roll Groover is designed to groove
schedule 10 and 40 steel, aluminum, and PVC pipe in

steel pipe. With a roll set change, it can be used to
groove 2" - 8" Type K, L, M and DWV copper tube.
The 975 Combo Roll Groover can be used for in
place applications (pipe that is in place or mounted
in a vise) or with a RIDGID 300 Power Drive or 300
Compact Threading Machine for power ed applica-
tions on the job site. The 975 Combo Roll Groover is
not intended for production type applications.
4. When grooving in place, make sure that there will be
enough space for the 975 Combo Roll Groover to fit
and be operated. The roll groover will orbit around
the solidly mounted pipe and requires:
• A minimum of 6

• A minimum of 2

• A minimum opening of 9

Roll groovers for other applications can be found
by consulting the Ridge Tool catalog, on line at
RIDGID.com, or by calling Ridge Tool Technical
Service Department at 844-789-8665.
NOTICE
Use of roll sets (groove roll and driveshaft) on
both carbon and stainless steel pipe can lead to contam-
ination of the stainless steel material. This contamination
could cause corrosion and premature pipe failure. To pre-
vent ferrous contamination of stainless steel pipe, use roll
sets dedicated for stainless steel roll grooving. Alternately,
a stainless steel wire brush may be used to thoroughly
clean the roll set when switching between materials.
Pipe Preparation
NOTICE
These are generalized instructions. Always
follow grooved coupling manufacturer's specific recom-
mendations for pipe end preparation. Failure to follow the
grooved coupling manufacturer's recommendations may
lead to an improper connection and cause leaks.
1. If grooving in place on an existing piping, make sure
that the system has been depressurized and emptied

of contents. Know what the contents are and any
hazards associated with them.
2. Cut pipe to proper length.
Make sure pipe end is cut square and free of burrs.
Burrs can catch or cut gloves or fingers during groov-
ing. Cut off method and large burrs can affect the
quality of the groove made and the tracking of the
Groove. Do not attempt to groove pipe that has been
cut with a torch.
" to
3. All internal/external weld beads, flash, or seams must
be ground flush at least 2" back from the end of the
pipe. Do not cut flats into gasket seat area, this could
cause leaks.
4. Remove all scale, dirt, rust and other contaminants at
least 2" back from the end of the pipe. Contaminants
can clog the drive knurls and prevent proper driving
and tracking of the pipe while grooving.
5. Make sure that the pipe to be grooved is solidly
mounted. The pipe must be able to withstand the
weight of the roll groover (28 pounds), and the force
and torque required for grooving without moving. For
pipe that is in place, it may make sense to re move
the pipe and groove at a pipe vise. In other cases, it
may be necessary to add other temporary or perma-
nent pipe supports. When using a pipe vise, make
sure that it is secure and will not tip during use. For
longer lengths of pipe, use appropriate pipe stands
to support the extra length.
Mounting The Roll Groover To The Pipe
1. Confirm that the 975 Combo Roll Groover has been
inspected and has the appropriate roll set installed.
Make sure that the support arms are tight in the body
of the roll groover or remove them completely for
better access in tight spaces. Next, install the ratchet
into the feedscrew and install the extension into the
manual drive square at the back of the roll groover.
Make sure both the ratchet and extension are se-
curely installed.
2. Make sure that there is enough space between the
groove roll and drive shaft for the pipe wall. If needed,
turn the feedscrew counter-clockwise to retract the
groove roll.
3. Securely grasp the roll groover. Do not lift with the
ratchet. Place the driveshaft into the pipe and make
sure that the cover plate is tight to the end of the
pipe (Figure 14). Tighten the feedscrew to bring the
groove roll into secure contact with the pipe. Follow
steps 3 and 4 from "Setting/Measuring The Groove
Diameter" . Once the groove setting gauge is returned
