About this product
Product Description
The DREMEL 442-02 is a steel crimped cup brush designed for use with rotary tools. It features a 1/2 inch brush diameter and a 1/8 inch shank that fits standard rotary tool chucks. Rated to 15,000 RPM, this brush is built for light deburring, surface prep, cleaning, and rust or scale removal on metal and other hard surfaces. Each package contains 2 brushes. The crimped steel fill provides consistent contact pressure and moderate aggressiveness, making it well suited for detail work and contoured surfaces where a larger wheel brush would be impractical.
This cup brush is used in metal fabrication, maintenance and repair, and general workshop applications. It attaches directly to a rotary tool and works on metal, welds, painted surfaces, and similar materials that require cleaning or light abrasive action. Technicians and tradespeople use it for removing oxidation, paint, and debris in tight or hard-to-reach areas. The small diameter makes it practical for precision surface work where larger abrasive tools cannot reach.
