It uses nylon filaments infused with 120-grit silicon carbide abrasive, delivering a consistent scratch pattern and controlled material removal on metal, wood, and composite surfaces. The arbor-hole mount fits standard grinder spindles without requiring an additional shank. Rated at a maximum of 6,000 RPM, this brush is suited for professional shop use where controlled abrasive action is needed on contoured or flat workpieces.\u003c\/p\u003e\u003cp\u003eThis wheel brush is intended for use on bench grinders, pedestal grinders, and straight grinders in fabrication shops, maintenance facilities, and trade workshops. It is well suited for deburring machined parts, light surface blending, cleaning weld scale, and preparing surfaces before coating or finishing. The 120-grit silicon carbide fill provides a medium-fine cut rate appropriate for ferrous and non-ferrous metals as well as plastics and composites. It is typically installed and operated by machinists, metal fabricators, and maintenance technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch outside diameter suits standard bench and pedestal grinder wheel guards\u003c\/li\u003e\n\u003cli\u003eCrimped nylon filaments with 120-grit silicon carbide abrasive for controlled surface finishing\u003c\/li\u003e\n\u003cli\u003eArbor-hole mount with no shank included — installs directly on grinder spindle\u003c\/li\u003e\n\u003cli\u003e6,000 RPM maximum speed rating for safe operation on rated grinders\u003c\/li\u003e\n\u003cli\u003e7\/8-inch trim length provides consistent filament contact and extended brush life\u003c\/li\u003e\n\u003cli\u003eCompatible with bench or pedestal grinders and straight grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on bench grinders, pedestal grinders, and straight grinders equipped with a standard arbor-hole mounting system.
