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.
