- What this kit does - Fast, controlled removal of rust, dirt, paint flaking, and corrosion from tight spots and small parts. Designed for both power and hand use so you can switch between speed and precision as the job requires. - Key benefits — why you need it - Versatility: 1/4-inch hex shanks let you mount brushes in a power drill or die grinder for quick work, while the soft, ergonomic handle lets you use the same brush heads manually for delicate or detailed cleaning. - Reach and access: The included 6-inch quick-release handle acts as an extension to reach narrow gaps, recessed connectors, and other hard-to-access areas. - Material options for the right finish: Stainless steel for heavy-duty abrasion, brass for softer metal surfaces and non-sparking applications, and nylon for light cleaning and finishing without scratching. - Reduced fatigue and better control: Soft, ergonomic handle improves grip and comfort during longer jobs, giving steadier results than hard-handled brushes. - What’s included - One 6-inch quick-release extension handle (long reach bar). - 12 stainless steel brush heads. - 12 brass brush heads. - 12 nylon brush heads. - Brush size ranges: - SAE (standard): 5/16" to 3/4" - Metric: 8 mm to 19 mm - 1/4-inch hex shank on brushes for drill or die grinder compatibility. - Performance and compatibility - Use the brushes in a drill or die grinder for faster material removal, or snap them onto the soft handle for controlled manual cleaning. - Multiple diameters let you match brush size to the workpiece for efficient cleaning without oversize contact or excess wear. - Choice of materials lets you balance aggressiveness and surface protection depending on the task. - Typical applications (practical scenarios) - Automotive battery maintenance: Remove corrosion from battery-terminal clamps and cable ends to restore conductivity and make a secure electrical connection. - Electrical and lighting work: Clean light sockets, contact surfaces, and small terminal posts before reassembly to ensure reliable contact. - Small engine and hardware maintenance: Clean threads, fittings, spark plug wells, and metal parts in confined spaces where a standard brush won’t reach. - Quick reference - Drive type: 1/4-inch hex shank — fits power drills and die grinders that accept 1/4" hex accessories. - Materials: Stainless steel, brass, nylon. - Extension: 6-inch quick-release handle included. - Brush counts: 12 heads per material (36 heads total) plus one handle. - Sizes: SAE 5/16"–3/4", Metric 8 mm–19 mm. This set gives you the right brush, size, and reach for routine cleaning, corrosion removal, and preparation tasks — with the flexibility to use power or hand tools depending on the job.
