It features a 33\/64-inch inside diameter and a 1-inch body outside diameter, with a 1\/2-inch length under the head. Constructed from steel, this bushing is pressed permanently into a drill jig plate without the need for a locking mechanism. The head sits flush against the jig surface to provide a positive stop and resist axial movement during drilling operations. Machinists, toolmakers, and fixture builders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for production drilling, reaming, and boring operations in metal fabrication, toolroom, and manufacturing environments. It fits applications where a permanent, non-renewable bushing is acceptable and where consistent hole location across repeated operations is required. The headed style provides bearing surface support on the jig plate face, making it appropriate for through-plate installations where the head seats on the top surface of the jig body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H press fit design installs permanently into jig plate without a locking ring\u003c\/li\u003e\n  \u003cli\u003e33\/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003e1-inch body outside diameter and 1-15\/64-inch head outside diameter for positive seating\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch head height provides a solid bearing surface against the jig plate face\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive drilling environments\u003c\/li\u003e\n  \u003cli\u003eNon-renewable configuration suited for fixed, permanent jig setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard drill jig plates requiring a Type H press fit headed bushing with a 33\/64-inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly sized jig plate bore. The plate bore must be machined to the correct interference fit tolerance before pressing the bushing in. Do not strike the bushing directly with a hammer, as this can damage the head or distort the bore. Once pressed in, this bushing is not intended to be removed or replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H Press Fit Headed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 33\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-15\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H648LP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51727370649906,"sku":"H648LP","price":22.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e756e61a6b7fffb91e139df978bfd5a5.jpg?v=1788676875","url":"https:\/\/voomisupply.com\/products\/boneham-h648lp-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
