The wheel measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole for standard surface grinder spindle mounting. Constructed from white aluminum oxide abrasive bonded with a vitrified bond, it delivers a fine, consistent cut on ferrous metals and hardened tool steels. The I hardness rating and semi-friable grain structure allow the wheel to self-dress slightly during use, maintaining a sharp cutting face and reducing heat buildup at the workpiece surface.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in maintenance, manufacturing, and tooling environments. It is appropriate for use on horizontal-spindle, reciprocating-table surface grinders. The fine 100-grit specification makes it well-matched for finish grinding passes where tight dimensional tolerances and smooth surface finishes are required. Machinists, tool grinders, and precision grinding technicians are the primary installers and operators of this wheel type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile for horizontal-spindle surface grinder applications\u003c\/li\u003e\n\u003cli\u003eWhite aluminum oxide abrasive with semi-friable grain structure for cool, sharp cutting\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent pore structure for controlled material removal\u003c\/li\u003e\n\u003cli\u003e100 grit, fine grade for finish grinding passes and close-tolerance work\u003c\/li\u003e\n\u003cli\u003eI hardness (soft rating) helps the wheel release dull grains and resist glazing\u003c\/li\u003e\n\u003cli\u003eNon-porous, no-recess construction with grain structure rating of 6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for horizontal-spindle surface grinders fitted with a 1-1\/4 inch arbor bore and capable of mounting a 7 inch diameter Type 1 wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be mounted and dressed by a qualified machinist or grinding technician following ANSI B11.9 and applicable shop safety standards. Always perform a ring test before mounting to check for cracks, and confirm the machine spindle speed does not exceed the wheel maximum of 3600 RPM before operation. Power down and lock out the surface grinder before changing wheels, and use the correct flanges and blotters for the arbor size. Never exceed the rated maximum RPM and never grind on the side face of a Type 1 wheel.\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\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I (Soft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003ePorous\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 23A100I6V31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 66253255903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51755760582962,"sku":"66253255903","price":40.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c96c0d3951f80e0009081d7c648bdff.jpg?v=1788959310","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253255903-surface-grinding-wheel-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
