It features a 0.750 inch inside diameter and a 1.250 inch outside diameter, with a length under head of 2.125 inches. The head thickness measures 0.265 inches. This bushing provides accurate, repeatable hole guidance for cutting tools in production and job-shop environments. It is installed by machinists and tooling specialists working with CNC machining centers, drill presses, and manual milling setups where consistent tool alignment is required.\u003c\/p\u003e\n\u003cp\u003eThis Type J bushing is suited for use in fixed liner applications within jig and fixture assemblies. The 0.625 inch hole diameter and 1 inch distance between hole centers make it compatible with standard jig plate configurations. It is commonly used in medium-duty production drilling operations across aerospace, automotive, and general metalworking applications where tooling accuracy and repeatability are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType J bushing configuration for fixed liner jig and fixture installations\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.750 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1.250 inches for standard liner fit\u003c\/li\u003e\n  \u003cli\u003eLength under head of 2.125 inches provides adequate tool engagement depth\u003c\/li\u003e\n  \u003cli\u003eHead thickness of 0.265 inches for positive seating against the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.625 inches with 1 inch center-to-center spacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard Type J rotary tool holder bushing applications in drill jig and fixture assemblies requiring a 0.750 inch inside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or tooling technician. Ensure the receiving liner or jig plate bore is clean and free of burrs before pressing or inserting the bushing. Power down all machine spindles and verify zero energy state before servicing or replacing tooling bushings in an active fixture. Follow applicable shop safety and workholding standards during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.265 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Hole Centers\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GLOBAL CNC INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8612J .750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GLOBAL CNC INDUSTRIES","offers":[{"title":"Default Title","offer_id":67910200230194,"sku":"8612J .750","price":104.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38c102ddb29bcb5ada0ede4716975b37.jpg?v=1791196634","url":"https:\/\/voomisupply.com\/products\/global-cnc-industries-8612j-750-tool-holder-bushing-type-j","provider":"Voomi Supply","version":"1.0","type":"link"}
