Forney 72739 4'' In. Hex Crimped, Coarse Drill-Mounted Wire Wheel Tackle tough cleaning tasks in tight spaces with the Forney 72739 4-inch hex crimped wire wheel brush, a heavy-duty cleaning tool designed for efficient rust, scale, and paint removal in hard-to-reach areas. Featuring a 1/4-inch hex shank, this wire wheel mounts directly into any standard 1/4-inch electric drill or pneumatic air drill (such as model 01990), providing secure, wobble-free operation for precise control and maximum power transfer. The 4-inch diameter wheel is constructed with coarse, crimped 0.012-inch steel wires that stay flexible under pressure, delivering effective brushing action without excessive material removal?ideal for light to medium-duty applications in metalworking, automotive repair, welding prep, and general maintenance. The crimped wire design ensures that bristles remain securely anchored to the hub, reducing wire breakage and extending brush life even under continuous use. Unlike twisted wire wheels, crimped styles offer a slightly softer touch, making them perfect for surface cleaning where aggressive material removal is not desired. The reinforced steel hub and solid hex shank allow the wheel to withstand speeds up to 6,000 RPM, ensuring compatibility with most high-speed handheld drills while maintaining balance and durability. This makes it an excellent choice for deburring edges, cleaning threaded holes, removing corrosion from bolts and fittings, or preparing weld joints. Weighing just 0.300 lbs and measuring 8.00 x 5.50 x 5.0 inches, the compact design enhances maneuverability in confined spaces such as narrow channels, corners, and recessed areas where traditional sanders or grinders can't reach. The bright metal wire construction provides excellent visibility during operation, allowing users to monitor cleaning progress in real time. Whether used in a workshop, garage, or on the job site, this drill-mounted wire wheel delivers consistent performance and long-lasting dependability?backed by Forney?s reputation for quality welding and metal preparation tools.
