Heavy-cleaning brushes have a double stem and carbon steel double-spiral bristles to remove rust and paint from carbon steel surfaces. Double-stem, double-spiral brushes have high bristle density and provide added rigidity. Carbon steel bristles remove material at a high rate on iron, carbon steel, and wood.

Long-life heavy-cleaning brushes have a double stem and carbon steel encapsulated double-spiral bristles to remove paint and rust from carbon steel surfaces. Encapsulated double-spiral tube brushes have a synthetic elastomer applied throughout the bristles to keep fibers together and reduce filament breakage. Double-spiral tube brushes have two rows of bristles wrapped around the stem for optimal surface contact. Double-spiral stems provide added support and rigidity, suitable for CNC machines and handheld power tools. Carbon steel bristles remove material at a high rate on iron, carbon steel, and wood.

Blind hole-cleaning brushes for carbon steel are single-stem with carbon steel bristles. Round tube brushes have bristles wound with the stem and are suited for cleaning and deburring threaded and smooth 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.

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.
