Weiler 93650 Stainless Steel Crimped Cup Brush 3.5 in

Product Description

The WEILER 93650 is a stainless steel crimped cup brush designed for surface preparation, weld cleaning, and deburring on metal workpieces. The brush measures 3.5 inches in diameter with a 0.014-inch wire diameter and a 7/8-inch trim length. Stainless steel fill material resists corrosion and is well suited for use on stainless steel base materials where carbon contamination from standard steel wire must be avoided. The crimped wire construction absorbs vibration and provides consistent contact across irregular surfaces. Rated to a maximum of 13,300 RPM, this cup brush mounts via a threaded 5/8-11 arbor and installs on compatible angle grinders and bench grinders.

This cup brush is used in industrial maintenance, fabrication shops, and field service applications where rust removal, scale removal, or surface blending is required on stainless steel or other metal substrates. It is appropriate for both ferrous and non-ferrous applications where stainless wire is specified to prevent cross-contamination. Typical users include welders, pipefitters, millwrights, and maintenance technicians working on structural steel, pipe, and fabricated assemblies.

Key Features

• 3.5-inch brush diameter for broad surface coverage in cup-brush applications
• Stainless steel crimped wire fill resists corrosion and prevents carbon contamination on stainless substrates
• 0.014-inch wire diameter delivers a balance of aggressiveness and surface finish
• 7/8-inch trim length provides controlled flexibility and consistent wire contact
• Threaded 5/8-11 arbor mount for secure attachment to standard angle grinders
• 13,300 max RPM rating supports use on common 4.5-inch to 5-inch angle grinders

Compatibility

Designed for use with angle grinders and bench grinders equipped with a 5/8-11 threaded arbor spindle, which is the standard spindle thread on most 4.5-inch to 5-inch angle grinders.

Installation Notes

Installation should be performed by a trained operator familiar with abrasive wheel safety per ANSI B11 and tool manufacturer guidelines. Disconnect and lock out power to the grinder before mounting or removing the cup brush. Ensure the grinder spindle speed does not exceed the 13,300 max RPM rating of the brush. Always use the appropriate guard and wear eye and face protection during operation.
