Value Collection B10374 Cup Brush 4in Stainless Knotted

Product Description

The VALUE COLLECTION B10374 is a knotted stainless steel cup brush designed for aggressive surface preparation on metal workpieces. The 4-inch diameter brush features 0.023-inch stainless steel wire in a knotted configuration, which delivers more aggressive cutting action than crimped fill. With a maximum rated speed of 10,200 RPM and a 1.25-inch trim length, this brush is suited for weld spatter removal, rust and scale stripping, and surface cleaning on ferrous and non-ferrous metals. It mounts via a standard 5/8-11 threaded arbor, compatible with most right-angle grinders.

This cup brush is used in fabrication shops, maintenance facilities, and field service applications where heavy surface conditioning is required. It is appropriate for use on structural steel, pipe, tanks, and similar metal surfaces. Licensed welders, pipefitters, millwrights, and general maintenance tradespeople are the primary installers and users. The single-row knotted wire design concentrates wire density for consistent contact on flat and curved surfaces.

Installation Notes

This brush is installed by a qualified operator or maintenance tradesperson familiar with angle grinder safety. Always power down and unplug or de-energize the grinder before mounting or removing the brush.
