CM-12 and CM-20 electric hydraulic pipe cutters share the same cutting principle but are designed for different pipe sizes and working environments. CM-12 is optimized for small to medium pipes in workshop use, while CM-20 is built for larger pipes and on-site operations requiring stronger support, stability, and mobility. Choosing depends mainly on pipe size and application needs.

The PTC140 bench-top pipe cutter is available in both AC-powered and lithium battery versions while maintaining the same cutting structure and performance. Designed for workshop and on-site use, it offers stable operation, easy handling, and flexible power options. Compatible with Makita batteries, the battery version supports mobile work without affecting cutting efficiency.

The second-generation AG-8Z Automatic Hydraulic Roll Grooving Machine introduces targeted upgrades based on real operating feedback. Improvements include an optimized hydraulic system for long-term operation, enhanced mobility with updated wheels and telescopic handles, optional wireless remote control, expanded grooving capacity up to 16", and a scaled depth-adjustment screw for easier, repeatable batch grooving.

The RG-1C roll grooving machine shares the same core grooving capability as the RG-1X, with the main difference in its fixed stand and wheels. The added structure does not change grooving performance, but makes stability and handling easier for fixed workshop use. It is ideal for continuous or repetitive grooving tasks at a set workstation.

This article explains why a pipe stand with a scale is more efficient for batch grooving work. In repetitive grooving operations, a scale provides a clear reference for pipe positioning, reducing repeated adjustments and inconsistencies between operators. By turning experience-based setup into reference-based positioning, a scaled stand helps maintain workflow continuity and improves efficiency in continuous and multi-operator grooving tasks.

A recent batch of Gruvmaster roll grooving machines has completed final assembly and shipment preparation.

The CM-12 is an electric hydraulic pipe cutting machine designed for cold cutting of 2"–12" steel and stainless steel pipes. It is mainly used in fixed or semi-fixed working areas such as workshops. With a split hydraulic system, pipe support stand, and durable cutting blade, the CM-12 provides stable and straightforward cutting for daily use.

This article documents a practical evaluation of a pipe cutting blade used on Gruvmaster pipe cutting machines. Based on real steel pipe cutting conditions, the blade was tested through repeated cutting cycles rather than single-cut results. The focus is on wear behavior, cutting stability, usable blade life, and compatibility across multiple machine models under normal working conditions.

This article explains a structural adjustment made to the CM-12 pipe cutting machine to better suit on-site use. While the cutting range, hydraulic system, and working principles remain unchanged, mobility has been improved by adding wheels and a tow handle. The update focuses on easier repositioning during on-site operations without affecting cutting performance.

The CM-20 pipe cutting machine has been updated with a split hydraulic system, replacing the previous integrated design. The hydraulic pump and cylinder are now installed separately and connected by hoses. This configuration is also applied across the 8", 12", and 20" pipe cutting machines, supporting more stable operation in workshop and on-site applications.

The Gruvmaster AG-8Z roll grooving machine has been updated based on real job-site use.

The new version features a larger hydraulic power unit, a telescopic handle for easier movement, and an expanded pipe size range from 1″ to 16″.

This article explains the structural updates of the Gruvmaster RG-4X Pro based on the RG-4X. The upgrades focus on practical improvements, including a frame with integrated storage, a larger grooving assembly, reinforced pipe support, and upgraded positioning rollers. These changes enhance stability, durability, and control during long-term roll grooving operations.

Roll grooving machines require different roller materials for different pipe conditions. This article compares plated rollers and stainless steel rollers used on Gruvmaster roll grooving machines, focusing on thin-wall pipe applications, groove quality control, durability, and cost considerations. Selecting the correct roller set based on pipe wall thickness helps improve grooving consistency and overall processing reliability.

Photos from the Gruvmaster factory show roll grooving machines during final assembly. At this stage, machines undergo alignment, fastening, fine adjustment, and inspection. Each unit is assembled by hand following a consistent process to ensure stable structure, smooth operation, and reliable quality before shipment.
