Heavy-duty rebar cutting machine for round steel, rebar, angle iron and flat steel. Models with cutting capacity up to 50mm.
A rebar cutting machine, also called a steel bar cutting machine or rebar cutter, is a powerful construction tool used to cut steel reinforcement bars quickly and cleanly. It is widely used on building sites, bridge projects, tunnel construction, precast concrete factories, and steel fabrication workshops. Our machines can cut round steel, deformed rebar, square steel, flat steel, carbon steel, and angle iron with high precision and minimal waste.
With cutting capacities from 25 mm up to 50 mm rebar diameter and operating speeds of 32 cuts per minute, our electric steel bar cutter range offers a fast, safe, and labor-saving alternative to manual cutting methods. Whether you need a compact SL40 rebar cutter for small jobs or a heavy-duty SL60 rebar cutting machine for large industrial projects, we provide reliable models to match your workload.
Our rebar cutting machine is used across many industries and job sites:
Building construction and high-rise projects
Bridge and highway construction
Tunnel and subway projects
Precast concrete component factories
Steel reinforcement workshops
Metal recycling and scrap yards
Suitable materials include:
Hot-rolled round steel
Deformed steel bars (rebar)
Square steel
Flat steel
Carbon steel
Angle iron
With interchangeable blade types, the same machine can be adapted for different cross-sections, making it a flexible investment for steel processing businesses.
Cutting Effect
Iron Cutter Working Principle
The electric steel bar cutter uses an electric motor to drive a flywheel and crank mechanism. When the operator steps on the foot pedal or activates the control switch, the flywheel releases stored energy to push the blade downward through the steel bar. The blade returns automatically via a spring system, ready for the next cut.
This mechanical design delivers fast, repeatable cuts with minimal operator effort. The fixed blade guide ensures that each cut is square and clean, reducing waste and improving the quality of rebar connections.
Main Advantages of Our Rebar Cutting Machine
Our automatic rebar cutting machine is engineered for durability and high performance. The key advantages include:
Thickened High-Strength Blades
The cutting blades are made from hardened alloy steel with reinforced thickness. They stay sharp longer and deliver clean, burr-free cuts even on high-strength deformed rebar.
Oversized Heavy-Duty Flywheel
The enlarged and thickened flywheel stores more rotational energy, providing smoother cutting action, stronger cutting force, and more stable operation under continuous load.
New Spring Bracket Design
The upgraded spring bracket improves blade return speed and reduces operator fatigue. It also helps absorb impact during cutting, extending the life of moving parts.
Versatile Blade Options
We offer three blade types to match different materials:
Circular blade – ideal for round steel and smooth bars
Straight blade – designed for rebar, flat steel, and square steel
Angle-iron blade – specially shaped for cutting angle steel and L-profile materials
This makes our steel bar cutting machine suitable for a wide range of metal profiles, not just reinforcement bars.

How to Choose the Right Rebar Cutting Machine
Selecting the best rebar cutter depends on the diameter and type of steel you process most often:
SL40: Best for light construction work, small contractors, and workshops cutting rebar up to 25 mm. The angle-iron version also handles 30×30 to 80×80 mm angle steel.
SL42 / SL45: Suitable for medium-sized construction sites and steel yards. The SL45 straight-thread model is ideal when cutting threaded bars up to 36 mm.
SL50: A strong all-rounder for commercial contractors cutting rebar up to 40 mm in diameter.
SL60: The heavy-duty choice for large infrastructure projects, precast factories, and industrial steel processing where bars up to 50 mm must be cut efficiently.
If your work involves mixed materials such as angle iron, flat steel, and carbon steel, choose a model with the matching blade type to maximize cutting performance and blade life.
