At 4 inches in diameter with a 1\/4-inch face width, this wheel operates at a maximum of 5,730 RPM and carries a 60-grit, J-hardness (medium) rating. The vitrified bond provides consistent stock removal on steel and ferrous tooling surfaces. Licensed tradespeople and tool room operators use this wheel on bench and pedestal grinders where controlled material removal and surface accuracy are required.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for tool room environments, maintenance shops, and light industrial settings where precision tool grinding is performed. The 4-inch diameter and Type 11 flaring-cup configuration make it a practical fit for resharpening cutting tools, drill bits, and similar shop tooling. The non-porous aluminum oxide structure maintains wheel integrity across repeated use cycles at rated speed. A 1-1\/4-inch hole size accommodates standard bench grinder spindle arbors common in trade and shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 11 flaring-cup wheel geometry for tool grinding and offhand applications\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cut\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness (medium grade) — specification code 32AA60-JVTR\u003c\/li\u003e\n  \u003cli\u003eRated to 5,730 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous gray wheel construction resists loading on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-inch hole size fits standard bench and pedestal grinder arbors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment grinding wheel for bench and pedestal grinders accepting a Type 11 flaring-cup wheel with a 4-inch diameter, 1-1\/4-inch hole, and standard arbor configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tool room operator or maintenance technician following applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
