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 applications
on the job site. The 975 Combo Roll Groover is not
intended for production type applications.
NOTICE Use of roll sets (groove roll and driveshaft)
on both carbon and stainless steel pipe can lead to con-
tamination of the stainless steel material. This contamina-
tion could cause corrosion and premature pipe failure. To
prevent 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.

drive/threading machine as directed in it's manual.
Make sure that the machine and stand are stable and
do not wobble.
5. Fully open the chuck of the power drive/threading
machine.

When using the 975 Combo Roll Groover with a 300
Compact Threading Machine, an adapter kit (Catalog

positions the 975 Combo Roll Groover relative to the
threading machine and stand and to allow the complete
range of sizes to be grooved. Do not try to use the 975
Combo Groover with any other threading machine, as tip-
ping or other issues may result.
1. Install the drive bar adapter onto the roll groover
drive shaft (See Figure 4) . Align set screws with the
flats on the roll groover drive shaft and firmly tighten.
