Norton 66252839014 Knotted Wheel Brush 6 in Carbon Steel

Product Description

The NORTON 66252839014 is a knotted carbon steel wheel brush designed for aggressive surface preparation and cleaning on metal and similar industrial workpieces. Measuring 6 inches in outside diameter with a 0.5 inch face width and a 1.5 inch trim length, it mounts via a 5/8-11 threaded arbor hole and operates at a maximum speed of 9000 RPM. The knotted wire construction applies higher contact pressure than crimped styles, making it effective for removing mill scale, weld spatter, rust, and heavy coatings. This brush is rated Coarse grade and uses carbon steel filaments in the 0.010 to 0.019 inch diameter range. It is installed and used by metal fabricators, industrial maintenance technicians, and welding professionals.

This wheel brush is suited for bench grinder or angle grinder applications where a threaded arbor mount is available. It is appropriate for heavy-duty deburring, surface conditioning, and weld cleanup on ferrous metals in fabrication shops, maintenance facilities, and industrial production environments. No shank is included, so a compatible 5/8-11 threaded spindle is required for mounting.

Key Features

• Knotted carbon steel wire for high-pressure, aggressive material removal
• 6 inch outside diameter with 0.5 inch face width for focused contact area
• 9000 RPM maximum rated speed for compatibility with standard bench and angle grinders
• 5/8-11 threaded arbor mount for secure, tool-free installation on compatible spindles
• 1.5 inch trim length provides consistent wire extension and contact force
• Coarse grade filaments in 0.010 to 0.019 inch diameter range for heavy-duty applications

Compatibility

Designed for use with bench grinders and angle grinders fitted with a 5/8-11 threaded spindle. Verify that the tool's maximum rated RPM meets or exceeds 9000 RPM before mounting.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety practices. Always power down and disconnect the grinder from its power source before mounting or removing the brush. Confirm the spindle thread size is 5/8-11 and that the grinder's rated speed is appropriate for a 9000 RPM accessory before operation. Wear appropriate PPE including eye protection and gloves, and inspect the brush for damage before each use in accordance with ANSI B11 and tool manufacturer guidelines.
