straight grinders, flexible shafts. The power source should preferably be of a variable-speed type to control fill expansion. Industrial-grade brushes recommended for use on high-speed power tools such as flexible shaft machines, straight grinders, and power drills. Uniform filament composition and density provides optimal balance and finish. Provides excellent abrasion and wear resistance, along with high flexing action. High strength filament able to remove heavy buildups. Good bend recovery. Uses in industries area x
