Description, Specifications
and Equipment
Description
The RIDGID No. 915 Roll Groover is designed to manually form standard roll grooves on pipe or copper tube
that is installed. The 915 is lightweight, only 23 lbs., and
capable of grooving steel, stainless steel, PVC and aluminum pipe from 11/4″ to 12″ and 2″ to 8″ copper tube
(Type K, L, M, and DWV). The 1/2″ hand ratchet rotates
a feed screw that advances a groove roll into the
pipe/tube to form a groove that meets specifications
required for mechanical coupling systems, and also
drives the 915 around the pipe.
When properly used, the Model 915 Roll
Groover makes grooves that are dimensionally within the
specifications of AWWA C606-87. Selection of appropriate materials and joining methods is the responsibility of the system designer and/or installer. Before any
installation is attempted, careful evaluation of the specific
service environment, including chemical environment
and service temperature, should be completed.

Roll Groover Inspection
WARNING
To prevent serious injury, inspect your Roll
Groover. The following inspection procedures
should be performed on a daily basis:
1. Inspect the Roll Groover for any broken, missing,
misarranged or binding parts as well as any other
conditions which may affect the safe and normal
operation of this equipment. If any of these conditions
are present, do not use the Roll Groover until any
problem has been repaired.
2. Lubricate the Roll Groover if necessary according
to the Maintenance Instructions.

3. Use groover rolls and accessories that are designed for
your Roll Groover and meet the needs of your application. The correct groover tools and accessories
allow you to do the job successfully and safely.
Accessories designed for use with other equipment
may be hazardous when used with this Roll Groover.
4. Clean any oil, grease or dirt from all handles and
controls. This reduces the risk of injury due to a tool or
control slipping from your grip.
5. Inspect the groove rolls to insure they are not damaged or worn. Worn groover rolls can lead to slippage
and poor quality grooves.
Roll Groover and
Work Area Set-Up
WARNING
To prevent serious injury,
proper set-up of the Groover and work area is
required. The following procedures should be followed to set-up the machine:
1. Insure work area has adequate lighting.
2. Clean up the work area prior to setting up any equipment. Always wipe up any oil that may be present.
3. Check the groove and drive rolls to insure they are the
correct size.
Use of roll sets on both carbon and stainless
steel pipe can lead to contamination of the stainless steel
material. This contamination could cause corrosion and
premature pipe failure. To prevent ferrous contamination, use roll sets dedicated for stainless steel grooving.
4. Make sure pipe/tube is secured and not free to rotate
prior to roll grooving.
• If pipe is not installed, use a bench vise or tristand
vise to secure the pipe. Pipe supports must be used
if pipe is greater than 36″ in length.
Failure to properly support the pipe can
result in the pipe falling.
Place vise and stands on a flat level surface. Be
sure the pipe, vise and stands are stable.
• If the pipe/tube is installed, care must be taken to
prevent pipe rotation or movement. Make sure that
the added weight and force required of the 915
can be supported by the pipe hangers and clamps.
Operating the 915 Roll Groover
WARNING
Do not wear loose clothing when operating a Roll
Groover. Keep sleeves and jackets buttoned.
Always wear eye protection to protect eyes from
dirt and other foreign objects. When working overhead, wear a hard hat and keep personnel clear of
area.
Keep hands away from grooving rolls. Do not wear
loose fitting gloves when operating groovers. Use
pipe stands to support pipe when using a pipe vise.
Unit to be hand driven only. Do not power with drill
or other types of units.
Pipe Preparation
1. Make sure pipe/tube end is cut square and free of
burrs. Do not attempt to groove pipe that has been cut
with a torch.
2. Pipe/tube out-of-roundness must not exceed the
total O.D. tolerances listed in the dimension specification
(Table 1).
NOTE! Determine out-of-roundness by measuring max-
imum and minimum outside dimensions at 90
degree increments. Compare minimum and
maximum numbers with pipe diameter column
in
Table 1
.
3. All internal or external weld beads, flash or seams
must be ground flush at least 2″ back from the pipe
end.
IMPORTANT! Do not grind flats on the pipe outside wall
where the coupling gasket seals (gasket
seat area).
4. The 915 Roll Groover will orbit around the pipe/tube.
Care must be taken that adequate space is provided
completely around material.
NOTE! The RIDGID 915 can roll groove pipe/tube with-
in 3

915 Roll Groover Set-up
IMPORTANT! To confirm the proper groove depth, test
grooves should be performed and checked
with a Pi tape.
1. At a bench or on the ground, rotate the feed screw
counter clockwise to “open” the groove roll from
the drive roll
(Figure 2)
.
Figure 2 – “Open” Groove Roll from Drive Roll.
NOTE! Ensure that groove set specifications matches
pipe/tube capacity to be grooved. See drive roll
for capacity.
IMPORTANT! Do not attempt to groove copper tube with
the steel groove set. Also do not attempt to
groove steel with copper groove rolls.
2. Place 915 onto pipe/tube with feedscrew accessible
(Figure 3)
.
Figure 3 – Placing Groover on Pipe
3. Push 915 into pipe/tube until fully engaged. End of
pipe should contact the drive roll flange
(Figure 4)
.
Figure 4 – Pipe Contact with Drive Roll Flange
4. Rotate the feed screw clockwise by hand until tight.
915 should now be held in position on the pipe/tube.
Adjusting for Groove Depth
NOTE! The groove depth must be adjusted for each
pipe/tube diameter and wall thickness.
1. With feedscrew handtight, run depth adjustment
screw down until it touches the pivot nut.
2. Back the depth adjustment screw off the number of
turns indicated in
Chart 1 (For Steel/Stainless Steel,
For Copper See Chart 2. These are approximate settings only).
NOTE! The distance between the depth adjustment
screw and the pivot nut equals roll groove depth.
Adjustments up or down, with test grooves, will
ensure proper groove depths for couplings.
