Twist Brushes 101

Abrasive Brushes

Twist Brushes

Twist brushes can be known by many names such as spiral brushes, tube brushes, and internal cleaning brushes. Most importantly, twist brushes serve as an integral component in many manufacturing and medical environments due to their effective cleaning, deburring and finishing capabilities.

Manufacturing twist brushes involves twisting filament between stem wires and machining the brush to the desired specifications with a finished stem end. This construction method allows the brush to be tailored for handheld use as well as for use in power drills, automated machines, drill presses and CNC machines. We offer a range of fill materials for use in our twist brushes including synthetics, abrasive nylons, wire and natural filaments.

Operating Parameters

When mounting a twisted brush in a collet or chuck, it is recommended to minimize the overhang of the stem to under an inch. This is particularly true with power tube brushes, and it is important to avoid any load conditions and operating speeds that can cause stem deflections and destructive bending. A safe operating speed from 100-500 RPM is recommended for most twisted brushes.

To reach into deeper holes we recommend the use of collet-ready shank mounted brushes or drill extension rods rather than increasing stem overhang.
