The Steel Wire Showerfeed Scrub Brushes feature 0.014in diameter fill material throughout the block. The steel wire brush is a very aggressive brush for use on unfinished concrete surfaces. The showerfeed design is water and chemical resistant and allows cleaning solution to flow through the brush onto the hard surface. Clutch plate sold separately.

Brush Size Note: It is recommended that a brush size 2 inches smaller than the machine size is used because of the flare of the brush fibers.
