PFERD 81800 3" Standard Twist Knot Wheel .012 SS Wire, 1/2-3/8" A.H.
PFERD power and maintenance brushes are used where exacting demands are placed on efficiency and outcome of surface conditioning, deburring, and cleaning operations.
This brush features knots that are twisted approximately 75% of the trim length. The loosely-twisted knots cover a larger surface area and are ideal for heavy-duty cleaning and surface conditioning on uneven surfaces. For weld cleaning, weld spatter removal, scale removal, cleaning and deburring.
