Weiler 93652 Cup Brush 4 in Crimped Steel 5/8-11 Arbor

Product Description

The WEILER 93652 is a crimped-wire cup brush designed for surface preparation, weld cleaning, and deburring on metal workpieces. The brush features a 4-inch diameter and is filled with 0.014-inch diameter crimped steel wire, which delivers consistent scrubbing action while resisting wire breakage under load. The 5/8-11 threaded arbor hole provides a secure mount to compatible angle grinders and bench grinders. With a maximum rated speed of 10,200 RPM, this brush suits demanding production and maintenance grinding tasks. It is a single-unit package weighing 1.5 pounds and is suited for trades professionals handling fabrication, pipefitting, or structural steel work.

This cup brush is used in industrial and commercial applications where aggressive surface conditioning is required. Typical scenarios include cleaning mill scale from steel plate, removing rust and paint prior to welding, and blending weld beads on structural members. The 1-3/8-inch trim length gives the wire sufficient flex for contour work while maintaining enough stiffness for flat-surface cleaning. HVAC sheet metal fabricators, pipefitters, ironworkers, and maintenance mechanics are the primary installers and operators of this type of brush.

Installation Notes

This brush is installed and operated by metalworkers, fabricators, and maintenance mechanics familiar with angle grinder safety. Always confirm the grinder's no-load RPM does not exceed the brush's 10,200 RPM maximum before use. Wear appropriate PPE including a face shield, gloves, and hearing protection when operating wire cup brushes at speed. Inspect the brush for damaged or splayed wire before each use and remove it from service if defects are found.
