Chaser Type Rebar Threading Machine

A rebar threading machine is a mechanical device that employs traditional thread cutting technology, specifically designed to process straight threads on the connecting ends of rebars. Rebar threader is widely used in industrial and civil construction scenarios requiring high-strength rebar connections. By using cutting dies to form straight threads on rebar ends, rebar threader enables efficient rebar connection, suitable for HRB, TMT and other rebars ranging from Φ12 to Φ50.

  • Rebar threader CHEERON thread processing machine operates reliably, equipped with cutting dies, and is mainly used for processing straight thread connections of rebars in construction projects.


  • From rebar clamping and peeling to thread cutting, the integrated processing workflow ensures efficient operation, high thread precision, and a high pass rate.


  • Rebar threader supports automatic mode operation, facilitates thread loading, and makes operation easy and labor-saving for operators.


  • Capable of processing 60° or 75° angle threads, this kind of rebar coupler manufacturing machine meets diverse engineering requirements.


  • Coupler threading machine thread processing machine is suitable for on-site mobile operations and widely used in bridge, tunnel, and high-rise building projects.

First, in bar preparation, the end of the rebar is cut and straightened for uniformity. Next, in the threading process, this versatile rebar threader uses carbide-tipped rollers or dies to cut precise threads onto the surface of the bar, with the motor rotating the bar against the threading head to form accurate threads. Finally, in coupler connection, once threaded, the bar can be joined with another threaded bar using a coupler, creating a strong, continuous line of reinforcement. This efficient process, powered by a reliable rebar threading tool, ensures that reinforcement structures are free from weak points, which is critical for modern construction projects.

Key steps of rebar threading machines production include designing, where engineers use CAD/CAM technology to create machines that can handle different bar diameters (commonly 16mm to 40mm). In material selection, high-strength alloy steel is used for the threading rollers and dies, ensuring they withstand wear and tear. During motor and gear assembly, powerful motors and durable gearboxes are fitted to provide smooth operation under heavy workloads. For frame construction, machines are built with heavy-duty steel frames for stability and vibration resistance. Finally, in testing, each unit undergoes trials to check threading accuracy, durability, and safety before reaching customers. As a trusted rebar threading machine supplier, Cheeron ensures its machines meet international standards, offering superior performance and long service life.

Rebar threading machines are used widely across different projects, often as a preferred rebar thread cutting machine or coupler threading machine for precise results. In residential buildings, they ensure stronger reinforcement for houses and apartments. For commercial complexes, offices and malls benefit from the reliability of threaded joints. In educational institutions, schools and colleges require sturdy frameworks, which threaded rebars provide. Additionally, in infrastructure projects, bridges, flyovers, and light industrial works increasingly adopt threaded connections using this rebar coupler threading machine technology. By adopting Cheeron's high-quality rebar threading machines, construction companies achieve greater safety, cost savings, and faster project delivery.
