Conductive brush with 0.003" stainless steel wire and a hand-laced aluminum handle. The stainless steel fill material is hand-laced with stainless steel wire into its handle for maximum fiber retention and durability. This high-quality brush has a 1 x 11 row configuration, with a 7/16" trim, and a brush face of 1-1/8" x 1/8". Ideal for aggressive cleaning in tight areas when light scratching is not a concern. The fine wire cuts through heavy grease with ease and can often reach into fine crevices better than natural hairs and synthetic bristles.
