Product Description

Product Introduction

Engineered for extreme performance and reliability, our 1300mm laser-welded diamond saw blades are the professional’s choice for cutting precast prestressed concrete, hollow core slabs, beams, and railway sleepers. With over 20 years of manufacturing expertise, we utilize premium diamond materials—including Element Six and high-grade domestic alternatives—integrated into a specialized bond matrix. This advanced matrix ensures aggressive, fast-cutting action through cured concrete, reinforced concrete, and hard brick without glazing, providing superior efficiency for heavy-duty construction and infrastructure projects.

The foundation of our concrete cutting disc is a high-toughness steel core sourced from leading manufacturing facilities, crafted from premium 30CrMo material (carbon content: 0.26-0.34). Every blade undergoes rigorous factory testing to ensure exceptional stability, featuring precise tolerances in diameter, thickness, and center hole dimensions (H8/H7 standards). We prioritize safety and international compliance; all our products are MPA and CE certified, meeting strict laboratory standards for cutting speed, wear resistance, and operational safety.

Designed for wide compatibility, our concrete saw blades fit seamlessly with walk-behind saws, high-speed gas saws, and road cutters (up to 35HP). We offer flexible steel core configurations, including Standard, Silent Sandwich, and Silt laser-cut options to suit your specific noise-reduction needs. Thanks to our 100% laser welding technology, these blades deliver superior strength and durability even under the most demanding conditions. While cutting performance varies based on slab thickness, aggregate type, and cable reinforcement, our blades consistently achieve optimal speeds, such as 1.8-2 m/Min for 200mm limestone aggregate slabs.

Features

100% Laser Welding

Utilizes state-of-the-art 100% laser welding technology to ensure maximum segment-to-core bond strength. Built for high-efficiency wet cutting, providing peak safety and structural durability during heavy-duty cutting operations.

Hard & Dense Materials

Engineered specifically for heavy precast structures. Smoothly and consistently cuts hollow core precast slabs, prestressed beams, and high-density precast railway sleepers without segment loss or glazing.

High-Speed & Longevity

Optimized bond matrices and premium diamond crystals deliver high-speed cutting action while achieving clean edge finishes. Long operational lifespan reduces blade changeover downtime and tool consumption costs.

Frequently Asked Questions

What machines are compatible with these diamond saw blades?
These blades are compatible with standard walk-behind floor saws, road cutters, and high-speed gas cutters powered up to 35HP, equipped with matching arbor sizes.
Is wet cutting required for these large-diameter blades?
Yes, continuous water cooling is highly recommended for optimal performance, dust suppression, segment preservation, and core longevity during deep cuts in dense prestressed concrete.
What makes 30CrMo steel core superior for concrete cutting?
The 30CrMo steel core delivers high tensile strength, fatigue resistance, and structural stability, maintaining blade flatness and preventing core deflection under intense operational loads.
Can the core design be customized for noise reduction?
Yes, we provide Standard, Silent Sandwich, and Silt laser-cut body configurations to accommodate strict job-site acoustic restrictions and reduce overall vibration.
What safety and quality certifications do these blades hold?
All our industrial diamond blades comply with stringent international standards and are certified with MPA and CE marks, guaranteeing tested operating safety and durability.
What cutting speed can be expected on precast slabs?
On standard 200mm limestone aggregate precast slabs, cutting rates consistently achieve 1.8 to 2.0 meters per minute depending on machine power and reinforcing steel configurations.
