Set of 8 nylon wire drill brushes with 1/4" hex shank, 8 drill brush sizes

Wide Compatibility: A complete set of 8 nylon brushes in sizes 75mm, 65mm, 50mm, 30mm, and 25mm, perfect for all drilling, deburring, polishing, grinding, etc., meeting professional working conditions. Applicable to All Materials: The nylon brush features coarse abrasive particles that effectively treat metal surfaces (including stainless steel/alloy), wood, plastic, PVC, ceramic tiles, and other materials, easily removing rust, oxide layers, welding slag, and coatings. Industrial-Grade Durability: The nylon drill brush set is made of safer abrasive materials than traditional materials, has high tear resistance, and withstands high speeds of 4500 rpm. They have a much longer lifespan than traditional wire brushes. Zero safety and risk: no sparks, no skin perforation, corrosion and rust resistant, nylon brush particularly suitable for flammable environments or the processing of precision parts, excellent chemical resistance, stable performance in both wet and dry applications. Multifunctional scenario coverage: A set of nylon drill brushes meets the requirements for rust removal (metal), polishing (wood), deburring (plastic), cleaning (stone), etc., covers operations on flat and curved surfaces in various sizes, and significantly improves work efficiency. Features: The nylon brush uses high-density nylon abrasive filaments, which are softer than traditional wire brushes. It quickly removes stubborn rust, oxide layers, and old coatings from metal, wood, plastic, etc., surfaces without scratching the workpiece and leaves the surface smooth. Reinforced nylon fibers and silicon carbide abrasives are tear- and heat-resistant, withstand high speeds of 4500 rpm, and do not easily deform or break after prolonged use. This nylon drill brush set has a significantly longer lifespan than ordinary abrasive brushes and requires less frequent replacement. It produces no sparks, rust, or loose filaments, making it suitable for flammable environments (e.g., fuel tank cleaning) and precision work; metal and wood can be safely treated.
