It uses a zirconia alumina abrasive grain, which provides aggressive stock removal and extended wheel life compared to standard aluminum oxide. Rated at 30 grit coarse grade, this mounted point is built for fast material removal on ferrous and non-ferrous metals. The 1\/4 inch shank fits standard die grinders and rotary tools. Maximum operating speed is 19,120 RPM. Machinists, tool and die makers, weld fabricators, and maintenance techs commonly use this type of point for internal bore work, cavity cleaning, and weld blending.\u003c\/p\u003e\u003cp\u003eThis mounted point is suited for use in manufacturing, fabrication shops, and maintenance environments where internal or contoured grinding is required. The W221 cylinder profile is effective for flat-bottom grinding, right-angle shoulder work, and side grinding inside housings, ports, and castings. The coarse 30 grit rating makes it appropriate for aggressive stock removal rather than finish work. It fits standard 1\/4 inch collet die grinders used throughout industrial and trade settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eW221 cylinder point shape for flat-bottom and side grinding applications\u003c\/li\u003e\n\u003cli\u003eZirconia alumina abrasive for aggressive cut rate and extended service life\u003c\/li\u003e\n\u003cli\u003e30 grit coarse grade optimized for rapid stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003e1\/4 inch shank diameter compatible with standard die grinder collets\u003c\/li\u003e\n\u003cli\u003e19,120 maximum RPM rating for safe high-speed operation\u003c\/li\u003e\n\u003cli\u003e3 inch overall length with 1.5 inch shank for reach into cavities and bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank mounted point for use with die grinders and rotary tools accepting W221 cylinder-profile mounted points at up to 19,120 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a die grinder with a compatible 1\/4 inch collet. Always confirm the tool spindle speed does not exceed the 19,120 RPM maximum rating marked on the mounted point before use. Inspect the shank for cracks or damage before mounting and ensure the collet is fully tightened. Wear appropriate eye protection and follow applicable ANSI B7 safety standards for abrasive product use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: W221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 19,120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\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: TM-221AB2SD2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51753012592946,"sku":"TM-221AB2SD2","price":27.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/247c2fc267ee99506f7721e0a31026f5.jpg?v=1788932131","url":"https:\/\/voomisupply.com\/products\/tru-maxx-tm-221ab2sd2-mounted-point-30-grit-w221-cylinder","provider":"Voomi Supply","version":"1.0","type":"link"}
