It measures 7 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses an aluminum oxide abrasive bonded in a vitrified bond matrix, rated at a J hardness code and medium grade. With a maximum operating speed of 3600 RPM, this wheel delivers consistent, controlled cutting action suited to surface and cylindrical grinding applications. It is installed and operated by machinists and tool-and-die technicians working in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is designed for surface grinding applications on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines. The Series 32A Type 1 construction is well suited to both production runs and precision one-off grinding tasks where consistent material removal and wheel life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for effective cutting on a wide range of ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and resistance to heat and coolant\u003c\/li\u003e\n\u003cli\u003eJ hardness code with medium grade for balanced wheel wear and cutting performance\u003c\/li\u003e\n\u003cli\u003eNon-porous, no-recess Type 1 flat wheel profile for standard surface grinding setups\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSpecification code 80J8V32A for precise identification and reordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFor use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
