Established in 2004, our facility has evolved from a specialized metallurgical lab into a premier Custom Double Cut Carbide Rotary Burr Set Manufacturer. With nearly two decades of focus on tungsten carbide synthesis, we provide the backbone for critical industries worldwide.
Headquartered in Guanghan, Sichuan, our facility integrates the entire value chain—from wet grinding and sintering to 5-axis CNC precision tooth opening. We are not just a factory; we are a strategic partner for the mining, aerospace, and automotive sectors.
The global shift toward automated deburring in CNC environments has increased the demand for "Double Cut" geometries. These patterns reduce vibration, allowing robotic arms to maintain higher feed rates without compromising the tool's structural integrity.
Modern procurement specialists are prioritizing "Circular Economy" tools. Our tungsten carbide sets are designed for extreme longevity, reducing the total carbon footprint per unit of material removed in heavy industrial applications.
With the rise of high-nickel alloys and titanium in aerospace, the need for burrs that resist thermal deformation is critical. Our 10% cobalt binder formulation ensures stability at RPMs exceeding 30,000.
A Double Cut Carbide Rotary Burr features two sets of cutting teeth that cross each other. This geometry provides several technical advantages for industrial users:
Our burr sets are engineered for:
The "Made in China" narrative has shifted to "Intelligent Manufacturing." As a leading factory, we have implemented Supply Chain Resilience through:
Mixing ultra-fine tungsten carbide powder with cobalt and rare earth binders in aviation-grade gasoline to ensure a molecularly consistent alloy.
Converting the mixture into a free-flowing granulate, removing moisture and impurities for a void-free final product.
Hydraulic molding of the powder into "green" blanks under high pressure, ensuring uniform density.
Sintering the blanks at 1,450°C in a Hot Isostatic Pressing furnace to eliminate porosity and maximize hardness.
The core of our quality: Advanced CNC grinding creates the sharp, precise double-cut geometry required for industrial performance.
Every batch undergoes ultrasonic flaw detection and Rockwell hardness testing to ensure zero-defect delivery.
Used by technicians in the German and Japanese automotive hubs for refining complex cavities in shoe molds and engine blocks.
Critical for cleaning welds and removing flash in massive steel structures where tool durability is non-negotiable.
Trusted by boutique metalwork studios for intricate detailing on copper and stainless steel art pieces.
A: Our burrs are manufactured from virgin tungsten carbide powder with 10% cobalt. Many retail burrs use recycled "scrap" carbide, which is prone to chipping and has a 50% shorter lifespan.
A: Yes. While 6mm (1/4") and 3mm (1/8") are standard, we manufacture extended shanks up to 150mm for reaching deep cavities in engine blocks and turbines.
A: We maintain a 6-month buffer of raw materials and utilize strategic logistics partnerships to ensure door-to-door delivery within 7-14 days globally.
