Osborn buffing brush
Osborn ‘nylon bristle’ abrasive buffing brushes are the industry standard. These are not a metal bristle cup brush, rather a nylon bristle (filaments), coated with (80) grit so you don’t have to worry about potential rust stains on your walls as the metal bristle style brushes tend to leave.
Technically, the Osborn ATB abrasive buffing brushes are not a peeling or debarking brush, whereas, Contractors use them to clean up the ‘fuzzys’ after Pressure Washing or Cob or Glass Bead blasting…and many a person has used them to sand the graying area on the sunny side of a faded wall.
- Bristles will flare out when in use and can reach in and clean notch areas.
- Also great for reaching the “lateral” area where one round log sits upon another.
- The bristles on these cup brushes are either round or square.The square is considered to be more aggressive.
- Rated to 6000 rpm. (try at +/- 1500 rpm).
- Works best on a Variable Speed Sander/Polisher…single speed units run at too high a speed. The Makita 9227C can handle either the 4″ or 6″ diameter brushes…whereas the Makita 9564CV is best with the 4″ (we’ve heard that the 6″ bushes tend to wear out the bearing on the 9564)
- Fits on 5/8″ threaded shaft (pretty much the standard in North America).
Other Osborn Abrasive Cup Brush Applications: Engine Blocks, Cylinder Heads, Exhaust Manifolds, Transmission Housings, Water Pumps, Intake Manifolds, Hydraulic Valve Bodies, Machine Components, Gears, Housings…Scotty uses one to scour out the underside of the riding mower blade housing prior to the winter coat of spray paint.
Sometimes called ‘ATB Cup Brushes’…that stands for ‘Advanced Technology Brushing’
NOTE: The ‘cup’ that holds the nylon bristles is metal.
