The best way for cutting rebar depends on the processing scenario, precision requirements, and production scale. The blade, as the core component, directly determines cutting efficiency and cut quality. The following suggestions are based on mainstream industry technologies in 2026, focusing on cutting methods and blade selection:
I. Optimal Cutting Methods for Different Scenarios
1. Large-scale Factory Processing – Hydraulic Rebar Cutting Machine (Best Efficiency)
Operation Method
Utilizes a high-power integrated hydraulic cutting production line, paired with high-wear-resistant rebar-specific blades, enabling simultaneous positioning and cutting of multiple rebars.
Core Advantages
Efficiency Breakthrough: Mainstream equipment in 2026 reduces single cutting cycle time to less than 1 second, with a daily processing capacity of tens of thousands of rebars, meeting the needs of large-scale production;
Extended Lifespan: Blades are strengthened through vacuum quenching treatment, increasing service life by 30%, significantly reducing downtime for blade replacement;
2. Construction Site Operations – Handheld Electric Hydraulic Shear (Best Convenience)
Operation Method
Uses a wireless rechargeable hydraulic shear, cutting rebar through the relative biting motion of the blades, without the need for external power or hydraulic lines.
Core Advantages
Flexible and Portable: Lightweight body, operation is not restricted by location, suitable for scattered cutting and high-altitude work on construction sites;
Safe and Environmentally Friendly: No sparks, low noise, greatly reducing fire hazards on construction sites;
3. Precision Connection Engineering – Metal Cold Saw Cutting (Best Precision)
Operation Method
Uses a low-speed circular saw blade for cold cutting. During the cutting process, the contact temperature between the saw blade and the rebar is low, without high-temperature oxidation.
Core Advantages
Extremely Smooth Cut: The cut surface is smooth like a mirror, without burrs or deformation, eliminating the need for secondary grinding;
No Material Damage: No high temperatures are generated during cutting, preserving the metallographic structure and mechanical properties of the rebar ends;
Suitable for High-End Requirements: Most suitable for engineering scenarios requiring high-precision threading, mechanical connection, or welding, ensuring the strength and stability of the connection.

The quality of the cutting effect is 80% dependent on the quality of the blade. By 2026, high-quality rebar cutting blades on the market will need to meet the following three core standards:
Material Selection: High-strength mold steel is the preferred choice.
High-performance mold steels such as H13, Cr12MoV are preferred.
H13 steel: Combines hot hardness and impact resistance, suitable for continuous cutting of high-strength rebar;
Cr12MoV steel: High hardness and excellent wear resistance, suitable for high-wear conditions such as cutting threaded steel;
Processing Technology: Vacuum heat treatment + surface coating for double assurance
Basic process: Must undergo vacuum heat treatment to ensure uniform hardness distribution of the blade and avoid local soft spots or cracks;
Upgraded process: Surface coated with TiAlN (titanium aluminum nitride) coating. The coating reduces the cutting friction coefficient, improves the wear resistance and corrosion resistance of the blade, extending its lifespan by more than 50%.
Structural Design: Four-sided usability for cost reduction and efficiency improvement
Square four-edged blades are preferred. When one cutting edge is worn, the blade can be rotated to use the other three edges. Compared with single-edged blades, this reduces consumable procurement costs by 75% and reduces the frequency of blade changes, improving production efficiency.
