Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action across its full face. At 150 grit with a K hardness code and grain structure of 6, it falls in the very fine grade range, making it well suited for light material removal and surface finishing rather than aggressive stock reduction. Rated to 3600 RPM and weighing 1 pound, it is a standard straight wheel intended for bench grinders and surface grinders used in machine shops, tool rooms, and maintenance facilities.\u003c\/p\u003e\u003cp\u003eThis wheel fits surface grinders and bench grinders that accept an 8-inch diameter wheel with a 1-1\/4 inch arbor hole. The 1\/4 inch thickness and Type 1 straight profile make it compatible with standard surface grinding applications where a flat wheel face is required. The white aluminum oxide grain with semi-friable characteristics makes it a common choice for grinding high-speed steel, tool steel, and similarly hard materials where heat-sensitive workpieces require a free-cutting, cool-running abrasive. No recess is present on either face.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, open cutting action\u003c\/li\u003e\n\u003cli\u003e150 grit, K hardness, very fine grade — suited for finish grinding and light stock removal\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain that self-sharpens to reduce heat buildup on sensitive workpieces\u003c\/li\u003e\n\u003cli\u003eNon-porous, grain structure 6 for uniform wheel density\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess for standard surface and bench grinder compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinders and bench grinders that accept an 8-inch diameter, Type 1 straight wheel with a 1-1\/4 inch arbor hole and a maximum spindle speed of 3600 RPM or lower.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation and dressing should be performed by a qualified machinist or maintenance technician following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the maximum RPM marked on the wheel. Use the correct flanges and blotter washers per the grinder manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\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: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 28A150K6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66253269566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51754399236402,"sku":"66253269566","price":85.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a846c527173c2e8ece177c02b888e73.jpg?v=1788945055","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253269566-surface-grinding-wheel-150-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
