LD-290 Knotted Wire Brush Wheel Flat Angle Grinder Heavy Duty | Wholesale Supplier

The LD-290 knotted wire brush wheel flat is a heavy-duty angle grinder attachment engineered for the most demanding industrial surface preparation and cleaning applications. Unlike crimped wire brushes, the knotted or twisted wire configuration provides maximum cutting aggression and stock removal capability, making it the preferred choice for heavy rust, thick mill scale, stubborn paint coatings, and heavy weld slag removal. The knotted wire bristles are manufactured from heat-treated carbon steel wire, twisted into tight bundles and secured firmly to the steel wheel hub, creating a robust and durable brush that maintains its shape and cutting performance even under extreme pressure and extended use. The flat wheel design provides a wide, stable working surface for cleaning large flat areas such as steel plates, beams, and structural components. The LD-290 features a precision-machined steel wheel hub with an M14 or 5/8-11 threaded arbor that ensures secure and concentric attachment to standard angle grinders, minimizing vibration and maximizing operator safety during high-speed operation. The brush is available in diameters ranging from 65mm to 125mm, accommodating a wide range of angle grinder sizes from compact 100mm models to larger 125mm and 150mm industrial grinders. The knotted wire bundles are strategically spaced around the wheel hub to provide consistent cleaning coverage while allowing debris to clear efficiently, preventing clogging and maintaining cutting performance throughout the life of the brush. Each brush weighs approximately 250 grams, and the heat-treated wire bristles offer extended service life compared to standard wire brushes, reducing replacement frequency and overall tooling costs. This knotted wire wheel brush is ideal for heavy industrial applications including shipbuilding, structural steel fabrication, pipeline construction, mining equipment maintenance, and heavy machinery refurbishment. It excels at removing thick rust, heavy mill scale, tenacious paint and protective coatings, and heavy weld slag from carbon steel and iron surfaces. The aggressive cutting action of the knotted wire configuration makes it particularly effective for surface preparation tasks where speed and material removal rate are priorities. The LD-290 is available in multiple diameter and wire thickness options, with full customization capabilities including OEM branding, private label packaging, and custom hub finishes. The minimum order quantity is 300 pieces with samples available for evaluation. The product is CE and ISO 9001 certified, manufactured under rigorous quality control standards to ensure consistent performance in the most demanding industrial environments.
