Product Overview

Our Industrial-Grade Round Steel Threading Machine is a specialized mechanical equipment designed for high-precision thread forming on round steel, steel bars, and bolts. As a derivative of pipe threading machines, it is engineered to meet the rigorous demands of construction, power engineering, mechanical manufacturing, and infrastructure projects, solving the pain points of low efficiency, poor thread accuracy, and high labor intensity of traditional manual threading methods.

Built with industrial durability and operational efficiency in mind, this threading machine adopts a precision gear transmission system and high-hardness cutting tools, ensuring that threads are formed in one pass with standard tooth profiles and smooth surfaces. Unlike ordinary threading tools, it features a fixed workpiece design—round steel remains stationary while the die rotates, allowing for processing of longer workpieces and improving operation stability. With a compact structure and moderate weight (around 110kg), it is easy to transport to construction sites, making it suitable for both fixed workshop production and mobile on-site operations.

Whether you are processing foundation bolts for power towers, connecting bolts for steel structures, or threaded components for mechanical parts, this industrial-grade round steel threading machine delivers consistent, reliable performance, significantly improving production efficiency and reducing labor costs. It supports both metric and imperial threads, and can be equipped with left-hand dies to produce left-handed threads, meeting diverse processing needs in different industries.

Industrial-Grade Key Features

Wide Processing Range: Supports round steel with a diameter of 8mm to 42mm, covering most common round steel specifications in industrial and construction scenarios, with strong versatility.
High-Precision Thread Forming: Adopts precision-machined gear transmission and high-hardness standard circular dies, ensuring threads are formed in one pass, with standard tooth profiles, no burrs, and high consistency, meeting GB/T 14791 and international industry standards.
Durable Industrial Structure: The machine body is made of high-strength cast iron and thickened steel plates,经过 aging treatment to reduce deformation, with strong rigidity and impact resistance, suitable for long-term heavy-duty operation.
Efficient & Labor-Saving Design: The workpiece remains stationary while the die rotates, which not only improves processing stability but also allows for processing of longer round steel. The automatic coolant spray system during forward and reverse rotation reduces tool wear and improves processing efficiency.
Easy Operation & Low Threshold: Humanized operation panel, simple parameter adjustment, no need for highly skilled operators, reducing training costs and improving work efficiency for enterprises.
Flexible Thread Compatibility: Compatible with standard circular dies (metric, imperial, NPT), which are easy to purchase and low in cost; supports left-hand dies to produce left-handed threads, adapting to diverse processing needs.
Portable & Versatile: Compact structure, moderate weight (about 110kg), easy to carry and move, suitable for both fixed workshop production and mobile on-site operations such as construction sites and power engineering sites.
Cost-Effective & Low Maintenance: Modular design, easy to disassemble and maintain; standard die accessories are widely available, reducing maintenance costs and equipment downtime; the overall structure is simple and reliable, with low failure rate.

FAQs

Q1: What is the maximum threading capacity of this tool?

A1: This cordless threader supports threading from 1/2" to 1-1/4" (15mm to 32mm) for both black iron pipes and reinforcing steel bars (rebar). It works with NPT/BSPT standard threads, meeting common plumbing, fire protection, and construction requirements.
Q2: Can this tool be used for both pipe threading and rebar splicing?

A2: Yes, it is a multi-functional unit. It delivers precision-cut, leak-tight threads on galvanized/black steel pipes for plumbing and gas lines, and also creates clean external threads on rebar for mechanical coupler splicing in structural concrete work.
Q3: What type of battery does it use, and how long does a charge last?

A3: It is powered by a high-capacity 21V lithium-ion battery. A fully charged battery can complete 50–80 standard threads (1/2" to 1" pipe) on a single charge, depending on material and size. The brushless motor design optimizes power efficiency for extended runtime on job sites.
Q4: Is it compatible with different thread standards and die heads?

A4: Yes, it features a quick-change die head system, compatible with standard NPT and BSPT thread dies. The package includes die heads for common sizes (1/2", 3/4", 1", 1-1/4"), with additional sizes available as OEM options.
Q5: How does this cordless model compare to corded threading tools?

A5: The cordless design eliminates power cord restrictions, making it ideal for confined spaces, multi-story buildings, and off-grid job sites. It offers comparable torque output to corded models, while reducing setup time and trip hazards, improving both efficiency and safety.
