Blades of The GQ60 Rebar Cutting Machine

The GQ60 rebar cutting machine is top-tier construction equipment, built for tough jobs like bridges, dams, and high-rise foundations. It cuts reinforced steel bars up to 60mm thick. To use it well, you need high-quality H13 and H13K blades—blades that handle heavy pressure without breaking, keeping your worksite safe, efficient, and your machine in good shape.

Low-quality blades are risky when cutting strong steel. The GQ60’s power can shatter poor blades, causing big problems:

At AlasMachinery, we make blades for the GQ60’s tough work. Our H13 and H13K blades have the right mix of strength, sharpness, and precision. Here’s what sets them apart:

We use H13 and H13K steels—known for great performance under stress:

Hardness alone isn’t enough—blades need to be tough too. Our H13/H13K blades go through controlled vacuum heat treatment and tempering. This gives them a hardness of HRC 58-62, so they:

Loose blades break easily. We use CNC grinding to make sure every blade fits perfectly in the GQ60’s knife seat (zero clearance). This reduces vibration—the main cause of chipping—and protects both the blade and your machine.

Downtime is costly on big projects. Our blades have 4 sharp edges. You can rotate them 3 times before replacing, which quadruples the blade’s life and cuts down on downtime.

To make your blades last longer and work well:

Dull or low-quality blades damage the GQ60’s motor and gears, leading to overheating and breakdowns. Our H13/H13K blades help you:

Our H13/H13K GQ60 blades are heavier than standard blades. We package them carefully:

Skip expensive distributors. We offer factory-direct prices on all H13/H13K GQ60 blades. We have large stocks and can ship them to your job site right away.

Don’t settle for blades that hurt your GQ60’s performance. Upgrade to our premium H13/H13K blades—built for power, precision, and durability. They’ll keep your project on track and protect your machine. With AlasMachinery, you’re not just buying a blade—you’re investing in safety, efficiency, and your equipment’s long life.

Question 1: What are the main material options for our rebar cutting blades?

Based on different working conditions and budget requirements, we offer three general industrial-grade alloy steel materials:

9CrSi (Alloy Tool Steel): An economical choice. It has good hardenability and machinability, suitable for cutting ordinary medium-to-low strength rebar, and is widely used in small and medium-sized projects.

Cr12MoV (Cold Work Die Steel): High-end wear-resistant type. High carbon and high chromium content, after heat treatment, it has excellent wear resistance, making it an ideal choice for continuous cutting of high-strength rebar. Its service life is much longer than 9CrSi.

H13 (Hot Work Die Steel/Red Hard Steel): High toughness and high wear resistance. It exhibits excellent resistance to chipping and thermal stability in rebar cutting applications, especially suitable for high-speed production lines or online cutting of hot-rolled rebar, and cutting of ultra-thick rebar and composite materials of scrap rebar.

Question 2: Why do my blades often chip? Is it a material problem?

Chipping is usually caused by the following factors:

Insufficient toughness: Using ultra-hard but low-toughness materials to cut large-diameter or ultra-hard rebar can easily lead to brittle fracture. In this case, we recommend switching to H13 material, as its excellent toughness can effectively absorb impact forces.

Improper clearance: Too large or too small a gap between the upper and lower blades will lead to uneven stress, resulting in chipping.

Insufficient heat treatment: Internal stress is not completely eliminated. All our blades use vacuum heat treatment technology to ensure uniform hardness from the inside out, greatly reducing the chipping rate.

Question 3: What is the biggest performance difference between 9CrSi and Cr12MoV?

Wear resistance: Cr12MoV has significantly better wear resistance than 9CrSi. Under the same working conditions, the number of cuts for Cr12MoV is usually 2-3 times that of 9CrSi.

Cost: 9CrSi is more cost-effective, suitable for projects sensitive to initial purchase costs; although the unit price of Cr12MoV is slightly higher, its lower replacement frequency results in a lower overall cutting cost per ton of rebar.

Question 4: Which material is recommended for high-strength deformed rebar (e.g., HRB500E) or thick rebar?

For high-strength or ribbed rebar, we strongly recommend H13:

If you are facing extremely high operating intensity and are concerned about downtime due to blade chipping, choose H13. Its impact fatigue resistance is top-notch in the rebar processing industry.

Question 5: Can you customize non-standard size blades according to drawings?

Yes. We understand that blade specifications vary among different equipment brands (e.g., from Italy, Germany, or China). We are equipped with a full set of CNC machining equipment, and you only need to provide the following information:

Detailed drawings (including length, width, thickness, and hole dimensions).

Material requirements (9CrSi, Cr12MoV, or H13).

Specifications of the workpiece to be processed (rebar diameter and strength grade).

We can provide a 1:1 precise customized solution.

Question 6: How to maintain the blades to extend their service life?

Regular rotation: Our blades are usually designed with 4 or 8 cutting edges. Please rotate the blade promptly when one cutting edge becomes dull.

Tighten bolts: Ensure the blades are securely installed. Any slight looseness will cause destructive impact during the cutting process.

Control the gap: Adjust a reasonable blade gap according to the rebar diameter, usually about 10% of the rebar diameter.
