The 4-inch Nylon Wire Cup Brush with 5/8”-11 Arbor Hole by BHA was designed with versatility in mind. These 4” x 5/8” cup brushes can be used on all metals, wood, tile, plastic, PVC, stone and more. They excel at removing rust, stripping paint, removing glue, sealant, mill scale, oxidation, excess grout, and prepping truck beds for bed liner. Nylon wire cup brushes like BHA’s will conform to the work piece as opposed to getting snagged on protrusions so they can be used on uneven surfaces including those with nuts, bolts, brackets, or rivets without catching edges. The bristles are flexible allowing for them flex around imperfections. The 4 inch Nylon Cup Brush is capable of moderate to light stock removal depending on the grit selected.
Nylon cup brush consists of heat resistant, nylon bristles, impregnated with abrasive grains. As the wire brush is used and the nylon wears away the filaments reveal new sharp abrasives creating a longer more consistent useable life when compared to metal wire brush alternatives. These cup brushes come standard with a 5/8”-11 arbor hole make them compatible with most variable speed angle grinders, polishers and buffers.
These cup brushes can be used wet or dry, are non-sparking, and remain cooler than metal wire brushes during use which protects not only the work pieces but the brush itself. BHA offers the 4 inch nylon cup brush in 3 grits: Gray – Coarse (80 grit) for higher stock removal such as removing rust from iron. Red – Medium (120 Grit) for more moderate stock removal such cleaning and prepping surfaces for sprayable truck bed liner coatings. Blue – Fine (240 Grit) for light cleaning and blending such as removing paint from finished woods or work on fiberglass.

After some brief testing it didn’t seem to work for what I needed done.. it left to of the red nylon on my wood test piece..so I never tried it on my Monkey Pod bench I’m making.
Well, I opened the box and the cone shape could have been an issue but the grinder flattened that to a great usable item that I used on many different materials mostly removing paint
Fast and easy website to navigate, great prices and quick shipping.
Easy to navigate website, quick shipping. 2 orders in so far and very happy with the quality of the orders.
I’m sanding the inside logs of my log home before applying a sealer. The 4” cup brush works great for removing the fuzz from pressure washing and smooths the knots while brightening the the log surface. I will probably use up to 10 brushes to completely sand the logs. The price per brush and the free shipping makes for an affordable solution for for my log home.
It is doing the job good However the cup shape changes to more of a flat plane shape than you would expect due to centrifugal force of the rpms of the angle grinder for which it was designed to be used. I do suppose we adjust the angle of the grinder to adjust.
