It measures 12 inches in diameter, 3\/4 inches thick, with a 3-inch arbor hole. The wheel uses aluminum oxide abrasive grain bonded in a vitrified bond matrix, producing a white, semi-friable wheel rated at medium grade with an I hardness code. At a maximum operating speed of 2,070 RPM, it delivers consistent cut rate and surface finish control on surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated weight is 6.78 pounds.\u003c\/p\u003e\n\u003cp\u003eThis wheel is well suited for grinding soft carbon steels, tool steels, and super alloys in both job shop and production environments. The vitrified bond provides rigidity and porosity control, making it a reliable choice for applications requiring dimensional accuracy and repeatable finish quality. It is a single-wheel package intended for professional machine shop and grinding operations where controlled material removal and wheel geometry matter most.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain structure for self-sharpening action on ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for rigidity and consistent form-holding during surface and cylindrical grinding\u003c\/li\u003e\n  \u003cli\u003eI hardness code, medium grade — balances grain retention with free cutting behavior\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered Type 1 flat wheel geometry with no recess\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 2,070 RPM — never exceed this value in operation\u003c\/li\u003e\n  \u003cli\u003eSpecification designation 38A60-IVBE for cross-reference and replacement ordering\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.
