Built to the 39C series specification, it uses a silicon carbide abrasive bonded in a vitrified matrix, producing a free-cutting action well suited to non-ferrous metals, stainless steel, and masonry surfaces. The wheel measures 6 inches in diameter by 1 inch thick with a 1-1\/4 inch arbor hole, runs at a maximum of 4140 RPM, and carries an I hardness code rated as medium grade. The green-colored wheel is non-porous with no recess and no taper, making it straightforward to mount and dress. Machinists, tool-and-die technicians, and CNC maintenance personnel are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production environments. The 80 grit, medium-grade combination delivers a balance of stock removal rate and surface finish quality. Typical applications include grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Its vitrified bond provides good form-holding under moderate to heavy grinding passes, making it a practical choice for flat surface work and light cylindrical operations where consistent cut geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide abrasive for effective cutting on non-ferrous metals, stainless steel, and masonry\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction holds wheel form and resists loading during continuous grinding passes\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade balances material removal rate with acceptable surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess and no taper for direct mounting\u003c\/li\u003e\n\u003cli\u003e4140 RPM maximum speed rating for surface and cylindrical grinding machine spindles\u003c\/li\u003e\n\u003cli\u003eGreen wheel color conforms to 39C series silicon carbide identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1\/4 inch arbor.
