✅ Soft brass wire construction provides a gentle yet effective cleaning action that won't scratch or damage hard metal surfaces like steel or iron.
✅ Flat-face "End" design (平口) is specifically engineered for cleaning the bottoms of blind holes, recessed areas, and flat internal surfaces.
✅ Solid 6mm steel shank ensures a universal fit for all standard power drills and high-speed air die grinders, providing stability at high RPM.
✅ Non-sparking properties make brass brushes the safest choice for working in environments where stray sparks from steel brushes could be hazardous.
✅ Highly effective for polishing delicate parts, removing carbon buildup from cylinder heads, and cleaning threads without stripping the base metal.
✅ Corrosion-resistant material ensures the brush remains effective over time, even when used with cleaning solvents or in humid workshop conditions.
