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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch outside diameter fits standard bench, pedestal, and straight grinder configurations\u003c\/li\u003e\n  \u003cli\u003eCrimped nylon filaments with 320-grit silicon carbide abrasive for controlled surface conditioning\u003c\/li\u003e\n  \u003cli\u003eArbor-hole mount — no shank included, seats directly on grinder spindle\u003c\/li\u003e\n  \u003cli\u003eRated to 6,000 RPM maximum for safe operation on compatible machines\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch trim length provides consistent filament contact and brush life\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch face width for focused deburring and blending on edges and narrow surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on bench grinders, pedestal grinders, and straight grinders equipped with a standard arbor-hole spindle.
