Abrasive Nylon Wire Polishing Drum

Designed for metal and wood both

For removing scale and rust on uneven surfaces, including surfaces with nuts, bolts, brackets, or rivets, 

without catching edges.

For grinding bark and rotten parts on uneven surfaces of wood, including wood with grooves, scabbed surfaces,

 and planar striations

Manufactured with abrasive-impregnated gray nylon bristles and sufficient void area (areas without bristles). 

The bristles are coarse, yet flexible allowing for them flex around imperfections, nuts and bolts without getting 

caught and damaging the grinder, drum, or workpiece. In addition to providing flexibility, the void space 

promotes airflow which prolongs the useful life of the wheel and reduces heat buildup that may damage a 

workpiece. Additionally, nylon drums can operate bi-directionally so if the bristles become too lopsided, simply 

flip the drum over for a fresh, coarse Nygrind.

With its open brush design and flexible nylon bristles, the 4.5-inch black hawk abrasives nylon wire abrasive drum

 is perfect for the following applications: Removing rust, scale, or other imperfections around nuts and bolts that 

would destroy other abrasive drums or discs. Specifically, cleaning rust off of frames and prepping the surface 

for a rust inhibitor. This drum is affixed with a hub that fits 3/4 inch keyed shaft and is made to be used on 

surface finishing machines and linear grinding machines (A.K.A. Burnishers, burnishing machines, contouring 

grinders, etc.)
