Gruvmaster Factory Story | 200 Manual Roll Grooving Machines Bound for the U.S.

Oct 22,2025
Inside the Gruvmaster assembly workshop, rows of RG-1M and RG-2M manual roll groovers stand ready for shipment.

This large batch — nearly 200 customized machines — was built according to OEM specifications in both color and configuration, and will soon be exported to the United States.
Both models feature a dual-mode design, supporting manual and power-driven operation.
The RG-1M covers a full pipe range from 1″–12″, suitable for workshop fabrication and on-site construction, while the RG-2M is tailored for 1″–6″ light-duty use, offering higher mobility and ease of operation.
Each roll grooving machine undergoes strict quality inspection and testing before delivery.
With their compact frames and portable toolboxes, these machines are ideal for field applications and confined spaces, providing smooth, efficient, and labor-saving grooving performance.
From light-duty manual types to heavy-duty hydraulic and fully automatic systems, Gruvmaster’s roll grooving machine lineup meets the needs of every pipe size and job requirement.
Whether it’s the portable RG-2M, the efficient RG-1X / RG-2X / RG-5X, or the flagship RG-8X and automatic AG-8Z, Gruvmaster ensures precision, durability, and reliability in every groove.
