It features a 0.375-inch inside diameter, a 1.5-inch outside diameter, and a 2.5-inch length under the head, with a head thickness of 0.265 inches. This bushing is used to guide cutting tools such as drills, reamers, and boring bars with precision alignment during machining operations. It is installed and serviced by machinists, toolmakers, and CNC setup technicians working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis Type J bushing is suited for applications requiring a head-style bushing seated in a drill jig plate or fixture body. The head style prevents the bushing from being pushed through the liner, making it appropriate for through-plate installations where the cutting tool enters from one face. Typical use includes production drilling, reaming, and similar guided-tool operations in metalworking and fabrication settings. The 1.125-inch distance between hole centers supports standard jig plate layouts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType J head-style bushing with 0.265-inch head thickness for positive seating in jig plates\u003c\/li\u003e\n\u003cli\u003e0.375-inch (3\/8 inch) inside diameter for compatible drill or reamer shanks\u003c\/li\u003e\n\u003cli\u003e1.5-inch outside diameter for press-fit or slip-fit into standard liner bushings\u003c\/li\u003e\n\u003cli\u003e2.5-inch length under head provides extended tool guidance depth\u003c\/li\u003e\n\u003cli\u003e1.125-inch distance between hole centers supports standard fixture layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling component for Type J rotary tool holder bushing applications in drill jig fixtures and machining tooling systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool holder bushings of this type are installed by toolmakers or machining technicians during jig and fixture assembly or maintenance. Ensure the mating liner bushing or jig plate bore is clean and dimensionally correct before pressing or seating the bushing. Power down all machine tools completely before servicing any tooling fixture. Do not force the bushing into an undersized bore, as damage to the bushing or fixture plate may result.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.265 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Hole Centers\u003c\/strong\u003e: 1.125 inches (1-1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 8603J .375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GLOBAL CNC INDUSTRIES","offers":[{"title":"Default Title","offer_id":67907335291186,"sku":"8603J .375","price":109.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82debe32539969a3e4a94a77f85b7bcb.jpg?v=1791177532","url":"https:\/\/voomisupply.com\/products\/global-cnc-industries-8603j-375-type-j-tool-holder-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
