It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond system, producing a coarse, semi-friable grain that fractures predictably during grinding to expose fresh cutting edges. Rated at a maximum of 2,705 RPM, it is designed for use on reciprocating and rotary surface grinders in shop and production environments. The I-hardness code and grain structure 5 make it well-suited for general-purpose surface grinding on steel and similar ferrous workpieces.\u003c\/p\u003e\u003cp\u003eThis wheel is used in machine shops, tool rooms, and manufacturing facilities where flat surface grinding is a routine operation. Typical applications include surface finishing, parallelism correction, and material removal on steel plates, blocks, and fixtures. The coarse 46-grit rating favors aggressive stock removal over fine finish work. It is installed and used by machinists, grinding machine operators, and tool-and-die professionals working with surface grinders that accommodate a 12-inch wheel with a 3-inch arbor bore.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile  -  no recess, straight face geometry for standard surface grinding\u003c\/li\u003e\n\u003cli\u003e46-grit aluminum oxide abrasive for coarse, high-removal-rate grinding on ferrous metals\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity control for consistent cut performance\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure self-sharpens during use, reducing glazing between dresses\u003c\/li\u003e\n\u003cli\u003eI-hardness (soft rating) releases dulled grains efficiently, extending effective cut life\u003c\/li\u003e\n\u003cli\u003eMaximum 2,705 RPM rating  -  match to grinder speed before mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinders accepting a 12-inch diameter, 1-inch wide, Type 1 wheel with a 3-inch arbor hole.

Power down and lock out the grinder before mounting or removing the wheel. Perform a ring test on the wheel before installation  -  a cracked wheel produces a dull sound and must not be used. Do not exceed the maximum RPM marked on the wheel; always verify the machine spindle speed is at or below 2,705 RPM.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I (Soft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrain Structure\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,705\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 29A46I5V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRU-MAXX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253269696\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":67593577431346,"sku":"66253269696","price":90.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04a7ca267df12d7a0f5c754caf701169.jpg?v=1790422500","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269696-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
