Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on ferrous metals and tool steels. The wheel measures 4 inches in diameter with a 1-1\/4 inch hole, a 1-1\/2 inch overall thickness, and a 1\/4 inch face width. At 60 grit with a J hardness code and medium grade, it is suited for general-purpose material removal where a balance of cut rate and surface finish is required. Maximum operating speed is 5,730 RPM.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in bench grinder and pedestal grinder setups for sharpening tooling, deburring, and surface conditioning of metal workpieces. The Type 11 flaring cup profile provides clearance at the heel and concentrates contact at the face, making it a common choice for sharpening lathe tools, drill bits, and other shop cutting tools. Typical users include machinists, maintenance technicians, and tool-and-die professionals working with steel and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, free-cutting action on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eType 11 flaring cup geometry provides heel clearance and face contact for precision tool grinding\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness (medium grade) balances material removal rate with surface finish\u003c\/li\u003e\n  \u003cli\u003eNon-porous construction maintains wheel integrity under standard dry grinding conditions\u003c\/li\u003e\n  \u003cli\u003eRated to 5,730 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eSpecification designation 32A60-JVBE for cross-reference and ordering verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on bench grinders and pedestal grinders accepting a 4 inch diameter, 1-1\/4 inch arbor hole Type 11 cup wheel.
