Description
19 lb Portable Roll Groover and Pipe Grooving Tool for Grooved Couplings
The Pace Mini-Mite roll groover is a portable pipe grooving tool that forms grooves in steel pipe for mechanical couplings. Roll grooving presses a circular channel into the pipe wall without removing material. The groove locks into a coupling that joins two pipe sections without welding or threading.
This combo roll groover weighs just 19 lbs and works two ways: use the included ratchet hand crank as an in-place pipe groover on scaffolds, ceilings, and mechanical rooms, or chuck it into a Ridgid 300 power drive for machine grooving. It handles 1-1/4" to 6" Schedule 40 and thin-wall steel pipe.
What's Included
- Pace 1039 Mini-Mite roll groover with built-in carrying handle
- Multi-function Ratchet Action Hand Crank (the only tool needed to operate)
Copper rolls for 2" to 8" pipe are available separately.
Key Features
- 19 lb total weight. Carry this portable roll groover up scaffolds, across rooftops, and between floors without fatigue.
- Self-contained ratchet hand crank. Operate this in-place pipe groover with the included hand crank wherever power is unavailable.
- Converts to a roll groover for Ridgid 300. Chucks in within seconds for machine grooving without removing the power drive gearbox.
- All hex drives are 15/16". One wrench adjusts every setting on this Pace Mini-Mite roll groover.
- 1-1/4" to 6" Schedule 40 capacity. Covers the pipe sizes most common in fire sprinkler, HVAC, and mechanical coupling systems.
- Optional copper rolls (2" to 8"). Expand this combo roll groover to handle copper pipe for plumbing and refrigeration work (sold separately).
- Compatible with multiple power drives. Also chucks into BERKLEY BT3000/BT5020 and MAXPOWER 50301 machines.
At 19 lbs, the Pace Mini-Mite roll groover carries to the scaffold, the ceiling, or the rooftop, then chucks into a power drive for machine grooving in the shop.

Applications
Roll grooving is a cold-forming process that presses a groove into the pipe wall so a mechanical coupling can clamp the joint together. Unlike cut grooving, a roll groove preserves the full wall thickness of the pipe. Once the pipe is grooved, it connects to Victaulic grooved fittings or other mechanical couplings for a joint that holds pressure without welding. This portable roll groover handles both field and shop grooving for these applications:
- Fire sprinkler branch lines, risers, and cross mains from 1-1/4" to 6"
- In-place grooving of HVAC chilled water, hot water, and steam piping in ceilings and mechanical rooms
- Field grooving for municipal water and wastewater pipe connections
- Shop grooving on a Ridgid 300 power drive for production pipe runs
- Maintenance and retrofit grooving on existing systems where welding is restricted or impractical
Fire sprinkler contractors consider the best roll groover for fire sprinkler work to handle the full branch line range and travel easily to the connection point. As a hand-crank roll groover, the Pace Mini-Mite operates without power, which matters in new construction where electrical systems are not yet active. When speed is the priority, mount it as a roll groover for Ridgid 300 power drives and groove pipe at machine speed in the shop or at ground level.

Frequently Asked Questions
What is roll grooving?
Roll grooving is a cold-forming process that presses a circular groove into a pipe wall using a set of rollers. The groove does not remove material from the pipe. Instead, the rollers reshape the wall to create a channel where a mechanical coupling seats and locks two pipe sections together.
What is the difference between a roll groove and a cut groove?
A roll groove forms the channel by pressing the pipe wall inward, keeping the full wall thickness intact. A cut groove removes material from the outside of the pipe with a cutting wheel, which reduces wall thickness at the groove. Roll grooving is more common because it maintains pipe strength.
What size pipe can you roll groove with the Pace Mini-Mite?
The Pace Mini-Mite roll groover handles 1-1/4" to 6" Schedule 40 and thin-wall steel pipe. Optional copper rolls expand capacity to 2" to 8" copper pipe and are sold separately. This range covers standard fire sprinkler, HVAC, and mechanical piping sizes.
How does a roll groover work?
A roll groover uses an upper and lower roller that spin against the pipe. The upper roller presses inward and forms the groove one revolution at a time. Depth increases with each pass until the groove reaches the correct dimension for the coupling.
Is the Pace Mini-Mite the best roll groover for fire sprinkler work?
The Pace Mini-Mite covers the full fire sprinkler branch line range from 1-1/4" to 6" at only 19 lbs. This hand crank roll groover fits on scaffolds and in ceiling spaces where power tools cannot reach. Email info@cleanflow.ca for help choosing the right portable roll groover.
