H13 Wear-Resistant Rebar Cutter Blade & High-Toughness Shear Knife

We supply three types of industrial alloy steel blades to fit different construction working conditions and budget needs. Each material delivers distinct performance for rebar cutting work:

9CrSi (Alloy Tool Steel)This is our most budget-friendly option. It offers good hardening performance and easy machining, making it ideal for small and medium construction projects. It works perfectly for cutting regular low and medium-strength rebar.

Cr12MoV (Cold Work Die Steel)A high-grade wear-resistant material with high carbon and chromium content. After professional heat treatment, it boasts outstanding wear resistance and far longer service life than 9CrSi. It is widely used for continuous cutting of standard high-strength rebar.

H13 (Hot Work Die Steel / Red Hard Steel)Our top-tier option that balances toughness and wear resistance perfectly. It resists chipping well and stays stable under high heat. It is the best choice for high-speed production lines, online cutting of hot-rolled rebar, ultra-thick rebar, and mixed scrap rebar cutting.

To support global purchasing and ensure full compatibility with worldwide cutting machines, our H13 rebar blades strictly follow international metallurgy standards, fully equivalent to three mainstream global grades:

Strict standard compliance ensures stable material composition, high purity and uniform internal grain structure. Our blades fit all mainstream European and Asian cutting equipment perfectly with zero dimensional errors or installation issues.

Chipping and softening are the most common blade failures during rebar cutting, mostly caused by poor material selection and low-standard heat treatment.

Main reasons for blade chipping

First, wrong material choice: Hard but low-toughness steel will chip or fracture when cutting large-diameter or high-strength rebar. Second, improper blade gap: Uneven gap between upper and lower blades leads to unbalanced stress and edge chipping. Third, incomplete heat treatment: Unrelieved internal stress leaves hidden structural flaws in ordinary blades.

Benefits of ALAS vacuum heat treatment

Most cheap blades use regular atmospheric quenching, which leaves residual internal stress and a soft core, causing easy deformation and damage. All our ALAS H13 blades adopt precise computer-controlled vacuum heat treatment. This process completely removes internal stress and delivers consistent hardness from the blade core to the edge. Most importantly, it fully unlocks H13’s unique red hardness. Even with continuous high-speed cutting and rapid temperature rises, the blade edge stays hard and stable, with no softening, deformation or chipping.

H13 steel is our exclusive recommendation for HRB500E ribbed high-strength rebar, ultra-thick rebar and high-frequency continuous cutting tasks. Featuring superior impact fatigue resistance, H13 handles constant harsh cutting impacts effectively. It avoids blade breakage and unexpected machine downtime, fully meeting heavy-duty industrial cutting requirements.

Yes, we provide full 1:1 OEM and ODM custom services for non-standard blades, compatible with all brands of cutting machines, including Italian, German and domestic Chinese equipment.

We have a large stock of standard-size blades for fast delivery, including 78×78×17mm, 80×80×30mm, 83×83×26mm and 100×100×20mm.

For custom orders, simply provide your detailed technical drawings (including length, width, thickness and bolt hole spacing), specify the steel grade (9CrSi / Cr12MoV / H13), and confirm your processing needs (rebar diameter and strength grade). Our full CNC workshop will produce perfectly matched, plug-and-play replacement blades.

Our square H13 blades are precision CNC ground with four usable cutting edges. Unlike regular single-edge blades that have to be discarded once dull, our blades can be rotated 90 degrees to use a brand-new sharp edge after one side wears out. This practical design quadruples the service life of each blade.

Paired with proper daily maintenance, it greatly cuts down blade replacement frequency and reduces your overall tooling cost per ton of processed rebar, delivering excellent long-term value for your project.

Basic daily maintenance can greatly improve blade performance and extend its lifespan. We recommend three simple but effective operations:

• GQ40: For small sites, cuts rebar up to φ32mm

• GQ50: All-round model for regular work, cuts rebar up to φ40mm

• GQ60: Heavy duty for thick rebar, cuts rebar up to φ50mm

• TYC-HD42A / TYC-D35: Stationary heavy-duty cutters for tough jobs

• TYC-NHD25 / TYC-HD19A: Light portable units, ideal for tight spaces and overhead work

• RC-16: Cuts rebar up to φ16mm

• RC-20: Cuts rebar up to φ20mm

• RC-25: Cuts rebar up to φ25mm

• LXR-HC24: Cuts rebar up to φ24mm

• LXR-HC26: Cuts rebar up to φ26mm

• LXR-HC38: Cuts rebar up to φ38mm

• LXR-HC45: Cuts rebar up to φ45mm

Why H13 Rebar Cutter Blades Are Ideal for Heavy-Duty Cutting

1. Reliable Material Performance

• Main components: Carbon, chromium, molybdenum, silicon, manganese and vanadium

• Impurities like phosphorus and sulfur: Controlled under 0.030%

• Hardness: HRC 50–55

• Great toughness and shock resistance, not easy to crack or chip

• Stays stable after long hours of heavy cutting

• Works well under high heat for thick, high-strength rebar

2. Compliant with Global Standards

• German DIN 1.2344

• Japanese JIS SKD61

3. Fine Craftsmanship & Heat Resistance

• Vacuum heat treatment
• Full CNC precision grinding
• Eliminates internal stress, ensures even hardness from core to cutting edge
• Boasts strong red hardness: Will not soften or go blunt even when heated by continuous cutting
• Sharp edges last far longer than those of regular blades

4. Smart Design & Cost Benefits

• Square blades (4 usable edges): Simply rotate the blade when one edge wears out. Service life is extended 4 times, ideal for large-scale cutting jobs.

• Rectangular blades (1–2 usable edges): Perfect for small rebar cutters.

5. Recommended Applications

• Large construction projects like bridges, highways and dams

• Cutting thick high-strength rebar (size #8 and above)

• Frequent, non-stop cutting work
