4 in Nylon Abrasive Wire Cup Brush

Description

The 4 in Nylon Abrasive Wire Cup Brush is a cup-shaped brush filled with abrasive nylon impregnated with aluminium oxide grit. Because it cuts without sparking, it is well suited to rust and paint removal on soft metals such as aluminium, where conventional steel brushes would mar or contaminate the surface; the flexible filaments conform to contours while carrying abrasive throughout the fibre. It measures 4 in in diameter, fits a 5/8-11 arbor, and is available in 80, 120, and 240 grit. Produced to order at our Yuantan factory cluster, the grit, fill density, and trim length can be specified to match your finishing requirements.

Abrasive nylon filament loaded with aluminium oxide combines the cutting action of a wire brush with the non-sparking, scratch-controlled behavior of nylon — the right choice for rust and paint removal on aluminium and other soft metals where a steel wire brush would gouge the surface or create spark hazards. Offered in 80, 120 and 240 grit on a standard 5/8-11 arbor to fit most angle grinders.

Choose coarser grit (80) for faster stock removal and heavier rust, or finer grit (240) for a smoother finish with less material removed. Tell us your surface and finish requirement and we'll recommend a grit.

Frequently asked questions

Why use abrasive nylon instead of a steel wire cup brush on aluminium?

Steel wire can gouge soft metals like aluminium and risks embedding ferrous particles that later rust; abrasive nylon cuts without those risks, which is why it's the standard choice for soft-metal surface prep.

Which grit should I choose?

80 grit for fast, aggressive rust/paint removal; 240 grit for a finer, smoother finish. 120 grit sits between the two for general-purpose use.

Is this non-sparking?

Yes — nylon abrasive brushes are commonly used specifically because they don't generate the sparks a steel wire brush would, relevant for spark-sensitive environments.
