Product: 1/4" hex-shank rotating wire brush set Key benefits Stronger connection: The 1/4" hex shank replaces a standard round shank to improve torque transfer and stability during use. This reduces the risk of loosening or slipping under load. High-speed performance: The rotating wire brush is designed to withstand speeds up to 4,500 min‑1 (rpm), allowing fast, efficient removal of rust, scale, paint and other surface contaminants without detaching or walking out of the tool. Precision in small spaces: The set includes wire wheels in two sizes (1 and 1.2) supplied as a separate 3‑piece pack, enabling finer work and better access in confined or detailed areas. Function, compatibility and materials Function: Rotating wire brush wheels for cleaning, surface preparation, deburring and detail finishing. Compatibility: 1/4" hex shank fits standard 1/4" hex chucks and quick-change holders that accept hex shanks. Construction/performance: Engineered to maintain secure seating and resist slipping during heavy-duty rotation up to 4,500 min‑1. Practical applications (examples) Rust and paint removal: Quickly strip rust, loose paint and scale from metal parts and small assemblies. Weld cleaning and prep: Clean weld seams and remove spatter before inspection or finishing. Deburring and detail work: Remove burrs and refine edges on small components and in tight corners where larger brushes cannot reach. What you get Secure 1/4" hex shank for reliable operation under load Rotating wire brushes rated to 4,500 min‑1 Two wheel sizes (1 and 1.2) in a separate 3‑piece pack for versatile, fine work This set is intended for users who need a compact, reliable wire-brush solution with improved shank stability and high-speed capability for both heavy-duty cleaning and detailed finishing tasks.
