The abrasive medium is aluminum oxide at 120 grit, rated Fine grade with a soft density, making it well suited for controlled material removal without aggressive stock takeoff. The point measures 2.75 inches in thickness with a 1\/4-inch shank diameter and 1\/4-inch shank length. Maximum rated speed is 10,730 RPM. This type of tooling is typically installed in die grinders, rotary tools, or tool-and-cutter grinders used in metalworking, mold finishing, and precision fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThe A3A120CXG 1\/4 is used wherever a small, shaped abrasive is needed to reach recessed geometry, internal radii, ports, or cast surfaces that flat or wheel-type abrasives cannot access. It is common in maintenance, repair, and fabrication applications across metalworking, tool and die, and light industrial trades. The tree profile of the A3 shape allows the operator to work along tapered or curved profiles with consistent contact. Machinists, tool and die makers, and general maintenance technicians are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA3 tree-profile shape for access to contoured, recessed, and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003e120 grit aluminum oxide abrasive, Fine grade for controlled surface finishing\u003c\/li\u003e\n  \u003cli\u003eSoft density construction reduces loading and heat buildup on softer base metals\u003c\/li\u003e\n  \u003cli\u003eRated to 10,730 RPM for use in standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits common collet sizes on die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds, minimizing tool fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders, rotary tools, and tool-and-cutter grinders fitted with a 1\/4-inch collet.

Always verify the tool spindle speed does not exceed the maximum RPM stamped or rated on the abrasive point. Wear appropriate eye protection and ensure the workpiece is properly secured before engaging the abrasive. Inspect the mounted point for cracks or damage before each use and discard any point that shows signs of deterioration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Tree (A3)\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: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity\/Hardness\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10,730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\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: CRATEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3A120CXG 1\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67909386797362,"sku":"A3A120CXG 1\/4","price":38.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/589f769a3c275432276ed06b771af9ed.jpg?v=1791186883","url":"https:\/\/voomisupply.com\/products\/cratex-a3a120cxg-1-4-mounted-point-tree-120-grit-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
