Gruvmaster has launched the new Gruv-Max heavy-duty roll grooving machine series, including GX24 and GX60. Designed for large-diameter and thick-wall steel pipe, the series covers pipe sizes from 8" to 60" with wall thicknesses up to 20 mm. OGS and AGS groove roll options are available for different piping applications.

The RG-4X Pro uses larger groove rollers than the standard RG-4X to improve forming stability during large-diameter pipe grooving. The upgraded roller design helps achieve more consistent groove quality and better control of pipe-end flare.

This article introduces the upgraded pipe cutting blades for Gruvmaster CM Series machines, including their applications, durability, maximum cutting wall thickness, and custom blade options. A real steel pipe impact test is also included to demonstrate cutting-edge strength and blade durability.

Discover how the Gruvmaster HC-1X Electric Pipe Hole Cutter makes steel pipe hole cutting faster, more stable and more accurate. This article demonstrates the complete pipe hole cutting process and explains how a professional pipe hole cutter improves efficiency in fire protection, HVAC and industrial piping applications.

This article records an AG-4X grooving test on a large-diameter steel pipe with an uneven end. Despite visible movement during rotation, the machine completed a continuous groove, showing how pipe condition, alignment and feed control affect groove quality.

Gruvmaster continues to improve its pipe cutting machines through blade testing, hydraulic system upgrades and long-term customer feedback. The current blade system includes one standard blade for carbon steel and stainless steel pipes, plus a dedicated blade for ductile iron. A separate, fully sealed hydraulic pump structure further improves sealing reliability, reduces contamination and lowers maintenance requirements.

A new batch of Gruvmaster HC-2X pipe hole cutting machines has completed assembly and practical factory testing. Designed for branch connection work in fire protection, HVAC and industrial piping systems, the HC-2X combines secure chain clamping, low-speed high-torque cutting, guided mechanical feed and flexible operation from either side. The result is a more stable and controlled way to prepare steel pipes for mechanical tees and other branch fittings.

The interlocking structure between the groove roller and drive roller plays an important role in roll grooving accuracy. It helps keep the rollers working together more steadily, supports better sealing surface control, and improves groove consistency during operation. This article explains how interlocking roll sets affect groove quality and why roller design, hydraulic stability, and pipe support should be considered together when selecting a roll grooving machine.

Gruvmaster is developing a new compact pipe cutting machine for 12–200mm pipes, a size range that is not commonly covered by professional pipe cutting machines on the market. Designed for installation, maintenance, MEP work, and small pipe prefabrication, this new model focuses on compact structure, stable clamping, and smoother cutting operation.

RG-4X Pro is a heavy-duty roll grooving machine designed for 8"–24" large-diameter steel pipe applications. With a new frame-type base, storage cabinet, reinforced pipe stand, Pro pipe stabilizer, and interlocking roll set design, RG-4X Pro provides improved stability, pipe support, and practical operation for large fire protection pipelines, industrial piping, workshop prefabrication, and job site use.

Stable pipe support is important when grooving long pipes. This article shows how AG-8Z uses interlocked rollers, an auxiliary stabilizing roller, and a pipe support stand to help reduce pipe wandering and keep the grooving process more stable in workshop and jobsite use.

This project is based on a customized AG-8Z automatic roll grooving machine for arc groove forming on metal pipe fittings. By combining a mature machine platform with targeted component adjustment, we provided a practical solution for a non-standard groove requirement and demonstrated our flexible customization capability in roll grooving equipment.

AG-8Z automatic roll grooving machine is designed for heavy-duty steel pipe grooving work. With Gruv-X hydraulic technology, one-push feeding, wireless remote control, and a heavy-duty roller structure, it supports stable operation and clean groove formation for workshop, jobsite, and pipe fabrication applications.

A sealed split hydraulic system can help pipe cutting and roll grooving machines work more smoothly in dusty and demanding jobsite conditions. By reducing the risk of hydraulic oil contamination, it supports more stable blade feeding, roller pressing, and long-term machine performance. This article explains why hydraulic system design matters for users who need reliable pipe tools for regular workshop or site work.
