Built on a vitrified bond with a semi-friable ceramic abrasive grain, it carries an 80 grit medium grade for efficient cutting action with consistent surface finish. The wheel measures 8 inches in diameter, 1\/4 inch thick, and features a 1-1\/4 inch arbor hole. Rated to 3600 RPM, it is designed for use in production and maintenance grinding applications performed by machinists and tool room technicians.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications across both job shop and production environments. Material applications include 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Its ceramic grain construction handles the elevated cutting temperatures common when working heat-sensitive alloys and hardened tool steels without excessive grain breakdown.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable structure for sharp, cool cutting on hard alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and dimensional stability during high-precision surface grinding\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade balances stock removal rate with acceptable surface finish\u003c\/li\u003e\n  \u003cli\u003eK hardness code with medium wheel hardness rating resists glazing on harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
