Light-deburring and -finishing brushes have a single stem and a single spiral of abrasive nylon bristles to smooth edges and surfaces of cross holes on all metals. Single-stem, single-spiral tube brushes have low bristle density, offer limited rigidity, and are suited for general-purpose cleaning and deburring. Abrasive nylon bristles are embedded with a coarse material along the entire length that continuously exposes fresh abrasive for a consistent surface finish. Nylon bristles are flexible and suited for plastic, aluminum, brass, and copper. They also offer improved safety compared to wire filament bristles, which are sharp and may fall off during operation.

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.

Internal thread-cleaning brushes have a single stem and stainless steel bristles. 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. Stainless steel bristles resist corrosion and heat, making them suitable for hot and wet environments. They can be used on aluminum, brass, copper, stainless steel, nonferrous surfaces, and wood.
