Weiler offers a comprehensives line of hand tube brushes for internal cleaning and deburring applications in tubing, pipe, drilled-and-tapped holes, and machined bores and passages. Due to their twisted-in-wire construction, the use of power tubes is limited to low-speed power tools such as drills and drill presses and to CNC and manual machine tools in which the RPM can be precisely programmed or set. Weiler Burritt Type tube brushes feature a 1/4" stem for convenient mounting into the chuck of a drill or the collet of a machine tool and allow the brush to be used in either direction of rotation. They allow the brush to be used in a standard cycle for deburring threaded holes in CNC centers. A flat burrite style tube brush is most effective used with a hold on blind, threaded holes.
