Silicon Carbide Filament Star Pipe Brush with Custom Bore and Custom Grit for Inner Wall Descaling and Deburring

Product Overview

This star rotary brush consists of silicon carbide abrasive nylon filaments molded on a reinforced plastic hub. The silicon carbide grains are evenly embedded inside the nylon filaments, delivering stable, controllable grinding performance. The star radial structure allows bristles to flex evenly during rotation, adapting naturally to curved inner surfaces. All key dimensions and grit grades can be adjusted according to customer requirements.
