Osborn 0002675500 Knotted Wire Wheel Brush 12 Inches

Product Description

The OSBORN 0002675500 is a knotted wire wheel brush designed for aggressive surface preparation and cleaning on metal, welds, and castings. The 12-inch outside diameter and carbon steel fill material make it well-suited for removing heavy rust, scale, weld spatter, and mill scale from structural steel and fabricated components. It mounts via a 2-inch arbor hole and operates at a maximum rated speed of 4,500 RPM. With a face width of 0.625 inches and a trim length of 3.25 inches, this brush delivers focused contact pressure for consistent stock removal. Licensed tradespeople and fabrication professionals working with angle grinders, bench grinders, or arbor-mounted equipment are the primary users.

This wheel brush is used in industrial fabrication, structural steel work, maintenance and repair operations, and heavy-duty surface conditioning applications. It is suited for bench-mounted or arbor-driven setups where the 2-inch arbor hole provides a direct, secure fit. Typical applications include pre-weld cleaning, post-weld cleanup, rust and coating removal, and surface preparation ahead of painting or coating. The knotted wire configuration increases wire stiffness and cutting aggressiveness compared to crimped wire designs, making it appropriate for demanding material removal tasks rather than light finishing work.

Key Features

Compatibility

Designed for use with arbor-mounted bench grinders and arbor-driven power tools accepting a 2-inch arbor hole. Verify spindle speed ratings meet or exceed the 4,500 RPM maximum before installation.

Installation Notes

Installation should be performed by qualified personnel following equipment manufacturer guidelines and applicable ANSI B11 or OSHA abrasive wheel safety standards. Always power down and lock out the machine before mounting or removing the brush. Confirm that the drive spindle speed does not exceed the 4,500 RPM maximum rated speed of the brush. Appropriate PPE including face shield, safety glasses, and heavy gloves should be worn during operation.
