Abrasive filament pipe brush is a precision processing tool with stainless steel wire as the framework and twisted abrasive brush filaments. It is mainly used for fine polishing and deburring of the inner wall of pipes. The brush filaments are made of high-quality abrasive filament material, with both grinding and cleaning properties. It can accurately remove tiny burrs on the hole surface after finishing, and at the same time improve the smoothness of the inner hole by 1-2 grades, suitable for pipes of various materials such as metal and alloy. The spherical brush head can automatically center and calibrate, covering the pipe wall 360° without dead corners, with uniform polishing and no scratches. Some models with tail design can go deep into long and thin pipes. There are various common specifications, with brush head diameters ranging from 20mm to 130mm and overall lengths from 25.4cm to 60.96cm, suitable for conventional industrial pipes and channels of precision components.
