Categories : Tools & Hardware
SKU : WOR-TOO-829
The RIDGID Model 975 2-in-1 Portable Combo Roll Grooving Machine (Catalog 25638) is designed for plumbers and pipefitters who need reliable grooves on pipe from 1/2 inch to 6 inches. It mounts onto the RIDGID 300 Power Drive for machine-powered grooving, or can be used manually on pipe that is already installed. Patented auto-tracking keeps the pipe engaged to the groover throughout the pass, producing consistent grooves with less effort.
When using the RIDGID 300 Power Drive, mount the 975 securely, set the permanently fixed depth gauge, and position the pipe in the rollers. The auto-tracking roller system automatically adjusts to keep the pipe centered on the groover. For manual work, the 55% higher gear reduction lowers the hand force needed, which is especially useful for overhead pipe.
This combo machine handles pipe from 1/2" to 6" and works in both machine-powered and manual modes. The ductile iron body handles heavy jobsite use, and the cast-in handle makes transport easier. Whether you’re grooving sprinkler pipe or HVAC line, the Model 975 is built to keep the job moving.

The Model 975 earns its “combo” name because you can run it by hand or bolt it to a RIDGID 300 Power Drive. For new pipe in the shop, power helps you move fast. For pipe already hung overhead, the manual mode makes repairs possible without cutting the line down.
1. Mount the groover or position it for manual work. 2. Open the rollers and insert the pipe. 3. Set the depth gauge to the required groove depth. 4. Rotate the rollers – manually or with the power drive – and let auto-tracking do the rest.
The permanently fixed depth gauge removes guesswork from the setup, so each groove comes out the same. Ductile iron construction protects the frame from jobsite abuse, and the cast handle makes it easy to carry between trucks and workstations.
Align the 975 with the mounting slots on the RIDGID 300 Power Drive, secure it in place, set the depth gauge, and position the pipe in the rollers. The auto-tracking feature will keep the pipe engaged during rotation.
Yes, it is designed for manual use, and the higher gear reduction makes manual grooving less tiring, especially overhead.
The Model 975 grooves pipe from 1/2 inch to 6 inches in diameter.
Auto-tracking is a patented feature that automatically keeps the pipe engaged with the groover until the groove reaches the preset depth, reducing the chance of slipping or uneven grooves.


I've been in the pipe business for decades and have used many groovers. This Model 975 is impressive. It's portable, which is a huge advantage on job sites. It works with my RIDGID 300 Power Drive, so I didn't have to buy a separate motor. The 2-in-1 feature allows me to do both roll and cut grooving without changing heads. The auto-tracking keeps the groove straight and consistent. It handles 1/2" to 6" pipe smoothly. It's a pricey investment, but it pays off.
Does the job. No issues.
I used this to groove some pipe for a sprinkler system. It worked great. It took a couple tries to get the tracking right.
This grooving machine is a beast. I've used it on several commercial jobs. The auto-tracking makes it easy to get a consistent groove. It's much faster than the old hand-crank method. It fits my RIDGID drive perfectly. The construction is solid, no wobble. The only negative is the price, but for a pro it's worth it. I'd recommend it to anyone doing fire protection work.
Good machine. The 2-in-1 feature is useful. It's heavy, but it gets the job done.
My husband loves it.
I'm a foreman on a plumbing crew. This groover has saved us so much time. We used to send out for grooving, now we do it on-site. It's easy to set up and operate. The auto-tracking is a lifesaver, no more measuring. It's built like a tank and handles daily use. The carrying case is a nice bonus. It's an expensive tool, but it's paid for itself already.
