In modern piping projects, the choice of a roll grooving machine can greatly affect efficiency, safety, and cost. Whether it’s fire protection, HVAC, or industrial piping, contractors rely on trusted tools to deliver consistent results. Gruvmaster has become a recognized brand in this field, and three models stand out as the most popular: RG-5X, RG-2M, and RG-1X. Each of these pipe roll groovers offers unique advantages for different jobsite needs.

The RG-5X roll groover is designed for versatility and power. With a capacity of 1″–12″, it handles most common pipe sizes with ease. Its hydraulic electric drive ensures efficient grooving and stable performance during continuous work. This machine is the ideal solution for medium-to-large projects, such as fire protection mains, large HVAC systems, and heavy-duty industrial applications. For more heavy-duty jobs, we also recommend our model RG-2X, with unique separate hydraulic pump and cylinder structure.

Compact and cost-effective, the RG-2M pipe roll groover is the perfect tool for light-duty applications. Covering 1″–6″ pipe sizes, it operates manually without the need for electricity. Contractors value it for its portability, low maintenance, and reliability in smaller job sites or emergency repairs. The RG-2M is also a popular choice in the rental market due to its ease of use. Versatile design, can be used manually or work with power drives and threading machines.

Balancing portability and efficiency, the RG-1X roll grooving machine is one of Gruvmaster’s most versatile models. With a pipe capacity of 1″–8″, it’s widely used in fire protection branches, HVAC piping, and small-to-medium industrial projects. Powered by an 800W motor with a steady 23 RPM speed, it guarantees uniform groove depth and reliable performance on site.
