Weiler 08219 Knotted Wire Wheel Brush 12 Inch Arbor

Product Description

The WEILER 08219 is a knotted wire wheel brush designed for aggressive surface conditioning, weld cleanup, and scale removal on metal workpieces. It mounts via a 1-1/4 inch arbor hole with a two-keyway style, making it compatible with bench grinders and pedestal grinders. The 12 inch outside diameter and 3/4 inch face width deliver broad contact across flat or curved surfaces. Carbon steel knotted wire with a standard twist knot construction provides the stiffness and cutting action needed for heavy-duty deburring and rust removal. Rated to 3,600 RPM, this brush is suited for sustained production use in fabrication and maintenance environments. Installation and use are handled by skilled trades including metalworkers, welders, and maintenance technicians.

The WEILER 08219 is applied in metalworking shops, fabrication facilities, and industrial maintenance settings. It mounts to bench or pedestal grinders and straight grinders with a compatible 1-1/4 inch arbor. Typical applications include weld spatter removal, mill scale stripping, surface preparation before coating, and general deburring of ferrous metal parts. The 2-3/4 inch trim length and knotted wire construction sustain consistent wire-to-work contact throughout the brush service life. This brush is not intended for use on aluminum or other soft non-ferrous metals without verifying wire compatibility with the base material.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel and wire brush safety requirements. Power down and lock out the grinder before mounting or removing the brush. Confirm the machine spindle speed does not exceed 3,600 RPM, and ensure the arbor hardware matches the 1-1/4 inch two-keyway bore. Always install and use appropriate eye and face protection, and verify that all guards are in place before operating.
