With a 3\/16 inch (0.1875 inch) inside diameter and a 3\/4 inch (0.7500 inch) outside diameter, this bushing provides precise tool guidance during machining operations. The head thickness measures 0.19 inches and the length under head is 1-1\/2 inches (1.5000 inches). Machinists, toolmakers, and CNC setup technicians install this type of component when building or maintaining drill jig fixtures that require repeatable, accurate hole location.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in production drilling, reaming, and boring setups across machine shop environments. Type B bushings are commonly pressed or slipped into liner bushings within jig plates, making them a standard component in fixture fabrication for both short-run and high-volume manufacturing applications. The 3\/16 inch bore accommodates tooling of that shank diameter, and the head keeps the bushing positively located against the jig plate surface during operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType B bushing configuration with a headed design for positive axial location in jig plates\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 3\/16 inch (0.1875 inch) for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 3\/4 inch (0.7500 inch) for standard liner bushing fitment\u003c\/li\u003e\n  \u003cli\u003eLength under head of 1-1\/2 inches (1.5000 inches) suits common jig plate thicknesses\u003c\/li\u003e\n  \u003cli\u003eHead thickness of 0.19 inches provides a low-profile seating surface\u003c\/li\u003e\n  \u003cli\u003eWeighs 0.2 pounds  -  lightweight for easy handling during fixture assembly\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 B rotary tool holder bushing applications in drill jig and fixture assemblies requiring a 3\/16 inch bore and 3\/4 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by toolmakers or machinists during fixture build or maintenance. Ensure the mating liner bushing bore and the jig plate counterbore are clean and free of burrs before seating the bushing. Press or slip the bushing into place per the fixture design specification, and verify that the head seats flush and square against the jig plate surface before use. Follow applicable shop safety procedures when working with press-fit components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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\u003eWeight\u003c\/strong\u003e: 0.2 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: 8601B .187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GLOBAL CNC INDUSTRIES","offers":[{"title":"Default Title","offer_id":67906058846514,"sku":"8601B .187","price":228.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73297b7b7efd56ebb6eeba7cae601773.jpg?v=1791163750","url":"https:\/\/voomisupply.com\/products\/global-cnc-industries-8601b-187-tool-holder-bushing-type-b","provider":"Voomi Supply","version":"1.0","type":"link"}
