3. Two Professional Blade Material Grades

Blade material directly determines cutting stability, wear resistance and service life. ALAS provides two mature high-grade steel materials to suit light, medium and heavy-duty cutting tasks and different rebar grades.

3.1 ALAS H13 (For Heavy-Duty Cutting & Anti-Chipping)

Hardness: HRC 50–55

vacuum heat treatment, H13 blades deliver excellent strength, heat resistance and impact resistance. They resist bending, cracking and edge chipping under continuous heavy loads. This grade is ideal for cutting Grade 60 and 500W high-strength TMT rebars, maintaining stable performance even under full hydraulic pressure during long-term large-scale construction.

3.2 ALAS Cr12MoV (For High Wear Resistance & Mass Production)

Hardness: HRC 55–64 (cutting edge: 58–62 HRC)

Cr12MoV steel features ultra-high hardness and superior wear resistance. It works best for hard cold-rolled rebars and high-strength deformed rebars. Suitable for non-stop mass production in rebar processing factories, it maintains precise cuts with minimal edge wear over long working hours.

4. Equipment & Application Matching Guide

4.1 Blade Shape Selection

Square 4-Edge Blade Block: Equipped with four independent cutting edges for extended service life. Ideal for medium and large cutters and high-volume, frequent rebar cutting work.

Rectangular 1–2 Edge Blade Block: Lightweight design for small hydraulic cutters, suitable for small construction sites and sporadic low-volume cutting tasks.

4.2 Standard Dimensions by Machine Model

All ALAS blades are precision manufactured with standard sizes and mounting holes for direct installation without field modification. Standard dimensions for common models are shown below:

GQ40 Cutter: 78×78×17mm, 80×80×25mm
GQ50 Cutter: 90×90×20mm, 110×110×28mm
GQ60 Cutter: 100×100×20mm, 100×100×30mm

User Tip: Always adjust the blade gap according to your machine’s official manual after installation to ensure clean, flat cuts and prolong the service life of both blades and equipment.

4.3 Material Selection by Rebar Type

Plain Round Rebar: Cr12MoV is the preferred option, offering stable wear resistance and excellent cost performance.

High-Strength Deformed Rebar (Grade 60 / 500W / HRB500 / HRB600): Choose H13 for heavy-duty cutting where impact resistance and anti-chipping performance are prioritized. Choose high-hardness Cr12MoV for high-frequency mass production requiring maximum wear resistance.

5. Quality Assurance

Every ALAS blade is finished with precision grinding and professional vacuum heat treatment. We enforce full-process standardized quality control and strict pre-delivery testing to guarantee stable and reliable quality:

Uniform overall hardness with consistent performance across all blades
Long-lasting sharp cutting edges with strong wear and chipping resistance
Effectively prevents common defects such as premature wear, cracking and edge breakage
Each blade undergoes mandatory hardness testing before shipment

9. Advantages for Cutting Grade 60 & 500W High-Strength Rebar

Grade 60 and 500W TMT high-strength rebars are widely used in bridges, building foundations and residential projects across Pakistan, Bangladesh and other Southeast Asian and African markets. These high-hardness rebars produce strong cutting impact during processing. Ordinary low-quality blades wear fast, chip easily and crack under load, causing frequent replacements, machine downtime and project delays. ALAS blades are specially engineered for these tough local working conditions:

9.1 Superior Impact Resistance of H13 Steel

With precision vacuum heat treatment, H13 steel maintains stable hardness at HRC 50–55, balancing hardness and toughness perfectly. It withstands strong instantaneous impact when cutting high-strength rebars, without bending, cracking or chipping under full hydraulic pressure, making it ideal for continuous heavy-duty construction.

9.2 Significant Cost Savings from 4-Edge Reusable Structure

The reusable four-edge design greatly lowers blade replacement frequency, effectively reducing spending on spare parts procurement, logistics and inventory, bringing obvious long-term cost advantages for large-scale rebar processing.

9.3 Perfect Fit for GQ Series Cutters

Precision manufactured dimensions fit GQ40, GQ50 and GQ60 cutters perfectly with no extra on-site adjustment needed. Standard blade gaps ensure smooth cutting surfaces, prevent rebar jamming, reduce machine vibration, protect internal components and extend equipment lifespan.

Rebar Cutter Blades FAQ

1. What rebar grades fit ALAS cutting blades?

Our blades are engineered for high-strength deformed rebar, covering Grade 60 (ASTM A615), 500W/500 TMT (BS 4449), 400B/500B, SD40/SD50, CB500-V, 500N, 500E with yield strength between 420–600 MPa. They also work well for mild plain round bars.

2. H13 or Cr12MoV, which material should I pick?

Choose H13 (HRC 50–55): For heavy continuous cutting of Grade 60 / 500W high-tensile rebar. Great impact toughness prevents edge chipping under frequent shock load.
Choose Cr12MoV (HRC 55–64, edge: 58–62 HRC): Ideal for hard cold-drawn rebar where superior wear resistance is prioritized under low-to-medium impact.
Cr12MoV is also a cost-effective option for general plain bar or mixed cutting jobs.

3. Will ALAS replacement blades suit my existing cutter?

Yes. All blades follow standard dimensions on thickness, mounting holes and cutting profile to fit GQ40, GQ50, GQ60 cutters directly. If your machine is outside the GQ series, share machine model or original blade dimensions, we can match existing stock or produce custom sizes.

4. What is 4-sided rotatable edge design and how does it extend service life?

Each square blade block features four usable sharp cutting edges. Once one edge wears dull, loosen bolts, rotate the block by 90° and refasten to use a fresh edge. One single block equals four conventional single-edge blades, cutting your spare part cost by extending usable lifespan 4x.

5. Do ALAS blades chip easily when cutting Grade 60 /500W rebar?

Proper installation eliminates chipping risk. H13 blades go through vacuum heat treatment at HRC 50–55, balanced in hardness and toughness to stand heavy impact from high-strength rebar cuts. Cr12MoV receives precision grinding to minimize cracking as well. Keep blade gap between 0.02–0.05 mm and center rebar straight during feeding for optimal results.

6. How long is the typical service life of ALAS blades?

Actual lifespan varies based on rebar grade, bar diameter, daily cutting volume and routine maintenance. Under correct operating conditions cutting Grade 60/500W rebar, our blades outperform standard generic blades by a large margin. Contact our technical team for customized lifespan estimate with your site data or request lab test reports.

7. Recommended blade clearance and its importance?

Set working gap at 0.02–0.05 mm between upper and lower blades. Too wide gap creates rough cuts with excessive burrs; too tight gap accelerates premature wear or sudden edge breakage. Always reset clearance after blade replacement or edge rotation.

8. How to handle dull cutting edges?

Rotate square four-edge block by 90° for unused sharp edge. Replace fully for rectangular single/double-edge blades. Running blunt blades lowers cutting efficiency and may damage cutter body.

9. Can you make custom-sized blades?

Custom fabrication available. Send original blade sample or engineering drawing for special dimension, hole layout or non-standard cutting edge per your working requirement.

10. Purchase terms & MOQ requirement?
