Value Collection S04185575 Cup Brush Knotted Steel

Product Description

The VALUE COLLECTION S04185575 is a knotted steel wire cup brush designed for aggressive surface preparation, weld cleanup, rust removal, and scale stripping on metal workpieces. The brush measures 2-5/8 inches in diameter and uses 0.0137-inch steel wire twisted into knots for increased stiffness and cutting action. It mounts via a threaded M10x1.25 arbor and is rated for a maximum of 12,500 RPM. The fine-grade, single-row construction makes it well suited for angle grinders and die grinders used by fabricators, welders, pipefitters, and maintenance mechanics who need consistent material removal without excessive surface damage.

This cup brush is used in fabrication shops, field pipe work, structural steel prep, and general maintenance applications where surface contamination must be removed before welding, coating, or inspection. The threaded arbor allows direct mounting to compatible angle grinders without a separate nut. Single-row knotted construction concentrates wire contact for focused cleaning on flat surfaces, inside corners, and around weld seams. It is appropriate for both shop bench work and field use on ferrous metal substrates.

Key Features

• Knotted steel wire construction delivers aggressive cutting action for rust, scale, and weld spatter removal
• 2-5/8 inch brush diameter provides focused surface contact for detail cleaning and seam work
• 0.0137-inch wire diameter with fine grade for controlled material removal
• M10x1.25 threaded arbor for direct grinder mounting without additional hardware
• 12,500 RPM maximum rated speed compatible with standard angle grinders
• Single-row design concentrates wire pressure for consistent, repeatable results

Compatibility

Designed for use with angle grinders and die grinders fitted with an M10x1.25 threaded spindle. Verify that the tool spindle thread matches M10x1.25 before mounting.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with abrasive tool safety. Always power down and disconnect the grinder from its power source before mounting or removing the brush. Confirm the tool RPM rating meets or exceeds 12,500 RPM and that the spindle thread is M10x1.25 before securing the brush. Wear appropriate PPE including eye protection and gloves, and inspect the brush for wire fatigue or deformation before each use.
