Weiler 90716 Stringer Bead Wheel Brush 4 Inch Ss

Product Description

The WEILER 90716 is a stringer bead wheel brush designed for weld cleaning, surface preparation, and scale removal in fabrication, manufacturing, and maintenance environments. It features a 4-inch outside diameter with stainless steel wire fill, making it suited for work on stainless steel and other materials where carbon steel contamination must be avoided. The brush runs at a maximum rated speed of 20,000 RPM and mounts via a 5/8-11 threaded arbor, which is a standard connection found on most right-angle grinders and die grinders used in trade and industrial settings. Metal fabricators, pipefitters, and maintenance mechanics are the primary installers and operators of this tool.

This wheel brush is used in weld preparation and post-weld cleanup applications where stringer bead wire geometry is needed to reach into tight weld joints, root passes, and narrow grooves. The stainless steel fill prevents rust transfer and cross-contamination on stainless steel workpieces and sanitary piping systems. It is appropriate for both shop and field use where a threaded-arbor grinder is available and where controlled, consistent wire action is required on metal surfaces.

Key Features

• Stringer bead wire configuration for reaching into narrow weld grooves and root passes
• Stainless steel wire fill prevents carbon contamination on stainless workpieces
• 4-inch outside diameter with 3/16-inch face width for focused cleaning action
• Rated to 20,000 RPM for compatibility with high-speed angle and die grinders
• 5/8-11 threaded arbor mount for secure attachment to standard grinders
• 7/8-inch trim length provides consistent wire reach and brush life

Compatibility

Designed for use with right-angle grinders and die grinders equipped with a 5/8-11 threaded spindle. Verify that the grinder's rated no-load RPM does not exceed 20,000 RPM before mounting.

Installation Notes

This brush is installed and operated by metal fabricators, pipefitters, or maintenance mechanics using angle grinders or die grinders. Always power down and disconnect the grinder from its power source before mounting or removing the brush. Confirm the tool's maximum RPM rating is at or below the brush's 20,000 RPM limit before operation. Wear appropriate PPE including a face shield and gloves, and follow ANSI B11 and OSHA abrasive wheel safety guidelines when operating wire brushes at speed.
