Internal thread-cleaning burrite tube brushes have a single stem and carbon steel bristles for removing rust and other surface contaminants from carbon steel blind and through holes. Burrite tube brush heads are flat and have bristles threaded through the stem at the end of the brush to clean and deburr threaded blind holes. Single-spiral stems have only two strands wrapped around the bristles, suitable for general cleaning and deburring by hand or with low-rpm power tools. Carbon steel bristles remove material at a high rate on iron, carbon steel, and wood.
