Industrial Grade Performance
& Advanced Material Science

Redefining the standards of concrete cutting with a perfect blend of endurance and agility.

Our 350mm x 20mm diamond blade stands as a benchmark in the non-metallic mineral products industry. By integrating high-concentration diamond segments and premium steel cores, we ensure that every cut is clean, accurate, and efficient. This tool is specifically engineered to maintain a stable cutting speed even when facing the densest reinforced concrete, making it an essential asset for professional road repair and infrastructure maintenance.

The technical edge of our 350mm x 20mm diamond blade lies in its adaptive bond technology. We offer softer bonds for standard concrete to maximize speed and harder bonds for reinforced materials to ensure long-term durability. Every single blade undergoes one-by-one inspection using professional testing machines, guaranteeing that variance is minimized and quality remains consistent across every batch produced over our 20-year history.

Engineering
Excellence

The core technical foundations that make our diamond tools the preferred choice for global contractors.

01

Diamond Bond Optimization

Precision-engineered matrix to ensure the optimal release of worn diamonds.

  • Variable Bond Hardness: Custom hardness to match abrasive material density.
  • High Diamond Grit: Selected synthetic diamonds for maximum abrasion resistance.
  • Wear Consistency: Uniform wear patterns to prevent blade warping.
02

Stability & Balance Control

Advanced vibration dampening to increase safety and extend tool life.

  • Precision Centering: Minimal run-out for cleaner cuts.
  • Thermal Management: Optimized segment gaps for cooling.
  • Core Strength: High-tensile steel prevents deformation.
03

Quality Assurance Rigor

Total quality control from raw diamond powder to finished product.

  • 100% Individual Inspection: No batch-sampling; every blade is tested.
  • Dynamic Balance Testing: Ensures safety at high RPMs.
  • Material Traceability: Full records of all raw materials used.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What is the main advantage of the 350mm x 20mm size?

This specific size provides an optimal balance between cutting depth and rotation stability, making the 350mm x 20mm diamond blade perfect for standard road saw machines and deep concrete cutting applications.

02

How do I choose between soft and hard bonds?

Soft bonds are recommended for harder materials like high-strength concrete to ensure the blade stays sharp. Hard bonds are designed for abrasive or reinforced materials to increase the overall lifespan of the segment.

03

Can these blades be used for wet cutting?

Yes, our blades are optimized for wet cutting to reduce dust and heat buildup, which significantly extends the life of the diamond segments and improves safety.

04

What is the average lead time for custom orders?

While standard stock ships immediately, custom specification orders typically have a sample lead time of around 7 days, followed by full production based on volume.

05

How do you ensure the stability of the quality?

We use professional inspection machines for 100% quality control. Each 350mm x 20mm diamond blade is verified for balance and segment adhesion before packaging.

06

What materials are these blades best suited for?

They are highly effective for cutting concrete, reinforced concrete, and abrasive stone materials commonly found in road construction and demolition projects.
