It features a 5\/16 inch (0.3125 inch) inside diameter and a 3\/4 inch (0.7500 inch) outside diameter, with a 1-1\/2 inch length under the head. The 0.19 inch head thickness provides a low-profile seating surface. Installed by machinists and tool-and-die professionals, this bushing locates and guides cutting tools with precision in high-repetition drilling and boring operations. The close-tolerance bore supports accurate tool guidance and consistent hole placement across production runs.\u003c\/p\u003e\n\u003cp\u003eThis Type J rotary bushing is suited for fixed or slip-renewable bushing applications in jig plates and drill fixtures used in light to medium machining environments. It is appropriate for both manual drill press setups and CNC-assisted fixture work where repeatable hole location is required. The 13\/16 inch distance between hole centers supports standard fixture spacing layouts commonly encountered in production machining and fabrication shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType J bushing configuration with a 0.19 inch head thickness for positive axial seating\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.3125 inches for 5\/16 inch tool guidance\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.7500 inches for standard jig plate fit\u003c\/li\u003e\n  \u003cli\u003e1.5000 inch length under head accommodates moderate jig plate thickness\u003c\/li\u003e\n  \u003cli\u003e13\/16 inch distance between hole centers supports standard fixture layouts\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 0.4 pounds for easy handling and installation\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 drill jig and fixture applications requiring a Type J rotary tool holder bushing with a 5\/16 inch inside diameter and 3\/4 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or tool-and-die technicians. Ensure all machine power is off and the fixture is secured before pressing or seating the bushing. Use a properly sized arbor press and installation drift to avoid damaging the bore or head seating surface. Verify bushing fit and alignment within the jig plate before resuming machining operations.\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: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.7500 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5000 inches (1-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Hole Centers\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eD (In)\u003c\/strong\u003e: 0.333 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 8601J .312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GLOBAL CNC INDUSTRIES","offers":[{"title":"Default Title","offer_id":67918351860018,"sku":"8601J .312","price":89.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d7323ad6d9d7f15430b6c489691632b.jpg?v=1791269313","url":"https:\/\/voomisupply.com\/products\/global-cnc-industries-8601j-312-type-j-tool-holder-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
