In industries such as metal fabrication, construction, and steel processing, a reliable and powerful 355mm cut-off machine is a must-have tool. These high-capacity machines deliver precision cutting of metal bars, pipes, profiles, and other hard materials. China has become a global hub for professional-grade cut-off machines, offering competitive pricing, robust build quality, and export-ready supply chains.

This 2026 guide helps industrial buyers understand key technical considerations, sourcing options, and leading Chinese manufacturers of 355mm professional cut-off machines.

What Is a 355mm Cut-Off Machine?

A 355mm cut-off machine (also known as a chop saw or cutoff saw) uses a 355mm (14″) abrasive wheel to cut metal and other hard materials. Typically used in workshops and construction sites, it's favored for: Precision straight cuts; High torque and cutting force; Durability under heavy duty cycles

Key parts include the motor, cutting wheel, guard, base, and safety systems. Industrial buyers often choose 355mm machines when they need higher cutting capacity and longer service life than smaller models.

Key Technical Parameters Industrial Buyers Must Know

To choose the right machine, pay attention to these performance factors:

① Motor Power & RPM

Higher power motors (often 1800W–2800W) ensure faster cutting and longer life.

Motor speed (RPM) should match abrasive wheel requirements for safe, smooth operation.

② Cutting Capacity

355mm wheel diameter supports cutting larger profiles such as thick pipes, solid bars, and heavy steel sections.

③ Duty Cycle & Cooling

Industrial use demands excellent heat dissipation and long duty cycles with minimal downtime.

④ Build Quality

Heavy-duty cast metal or steel bases reduce vibration and improve cutting precision.

⑤ Safety Features

Quality blade guards, electronic braking systems, and emergency stop switches are essential for workplace safety.

⑥ Portability & Weight

Some industrial buyers prefer semi-portable units with handles and wheels for on-site use.

How to Choose the Right 355mm Cut-Off Machine

When evaluating suppliers and models, consider:

Heavy-Duty vs Standard Models: Heavy-duty machines are more robust and suited for daily industrial use.

Electric vs Petrol Drive: Electric models dominate industrial workshops due to stable power and lower operational costs.

Maintenance & Spare Parts: Easy access to replacement parts saves time and money over the machine’s lifespan.

Warranty & After-Sales Support: Look for suppliers offering reliable global service centers or parts support.
