Built to standard ANSI shapes, this mounted point uses a unitized abrasive construction that integrates the abrasive material throughout the wheel body rather than coating only the surface. This design delivers consistent cut and finish as the wheel wears, making it a reliable choice for controlled material removal and surface conditioning work. The A21 shape with a 1\/4-inch shank fits standard die grinders and rotary tools used in fabrication and finishing operations. Grade is 8A Medium, suited for moderate stock removal with a refined surface result.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is intended for use in light deburring, edge blending, and surface conditioning applications on metal components and plastic parts. It is well suited for production finishing environments where a consistent scratch pattern and part geometry must be maintained. Typical users include machinists, fabricators, and metal finishing technicians working with precision or delicate workpieces where aggressive abrasives would cause damage or dimensional loss.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUnitized abrasive construction provides consistent performance throughout the life of the wheel\u003c\/li\u003e\n  \u003cli\u003eA21 ANSI standard shape with 1\/4-inch shank for compatibility with common rotary and die grinder tooling\u003c\/li\u003e\n  \u003cli\u003e8A Medium grade balances surface conditioning with controlled material removal\u003c\/li\u003e\n  \u003cli\u003eEffective on both metal and plastic substrates without aggressive surface damage\u003c\/li\u003e\n  \u003cli\u003eScotch-Brite EXL surface conditioning technology designed for delicate deburring and finishing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard die grinders and rotary tools accepting a 1\/4-inch shank mounted point.

Ensure the tool is powered off and unplugged before mounting or removing the point. Confirm the tool RPM rating meets or exceeds the mounted point maximum rated speed before operation. Inspect the wheel for damage before each use and discard if cracking or deformation is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: A21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 8A Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011647968\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010329840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346938167602,"sku":"7010329840","price":1159.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523626.jpg?v=1782094992","url":"https:\/\/voomisupply.com\/products\/3m-7010329840-unitized-mounted-point-a21-8a-medium","provider":"Voomi Supply","version":"1.0","type":"link"}
