Weiler 31104 Wheel Brush 4 in Crimped Nylon 320 Grit

Product Description

The WEILER 31104 is a 4-inch diameter wheel brush designed for surface conditioning, deburring, and light material removal on bench grinders, pedestal grinders, and straight grinders. It uses crimped nylon filaments loaded with 320-grit silicon carbide abrasive, delivering consistent scratch patterns and controlled cut rates on metal, plastic, and composite surfaces. The arbor-hole mount seats directly on standard grinder spindles with no shank required. With a maximum rated speed of 6,000 RPM, this brush suits production and maintenance environments where controlled finishing is required. Machinists, fabricators, and maintenance technicians are the primary installers and users.

The WEILER 31104 is suited for use on bench or pedestal grinders and straight grinders in industrial, manufacturing, and maintenance shop settings. The 320-grit silicon carbide fill makes it appropriate for fine surface conditioning, light deburring, and blending on workpieces where a consistent finish is needed. The 1/2-inch face width allows focused contact on narrow surfaces or edges. This brush is typically used in metal fabrication shops, maintenance facilities, and production environments requiring repeatable surface finish results.
