It features a 27\/64 inch inside diameter and a 3\/4 inch body outside diameter, with a 1\/4 inch length under the head. Manufactured from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance and dimensional stability required for repetitive drilling operations in production and maintenance environments. It is installed by press fitting directly into a drill jig plate without the need for a locking mechanism.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and fixtures across a wide range of manufacturing and machining environments, including metalworking shops, fabrication facilities, and MRO operations. The headed design prevents the bushing from being pushed through the jig plate during drilling, making it appropriate for through-hole jig applications where a fixed, non-renewable bushing is acceptable. Installation is permanent and does not require a liner bushing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType H press fit headed design for permanent, fixed installation in drill jig plates\u003c\/li\u003e\n\u003cli\u003e27\/64 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate drill guidance\u003c\/li\u003e\n\u003cli\u003e3\/4 inch body outside diameter and 59\/64 inch head outside diameter\u003c\/li\u003e\n\u003cli\u003e1\/4 inch length under head with a 7\/32 inch head height\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for long service life under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ANSI Type H press fit headed drill bushing for use in drill jigs and fixtures requiring a 27\/64 inch drill guide bore and a 3\/4 inch body press fit diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolmakers using a press to seat the bushing flush into a properly reamed jig plate hole. Power down all machinery before performing any jig plate work. The press fit is permanent and the bushing is not renewable, so the jig plate bore must be accurately sized before installation. Refer to ANSI standards for recommended jig plate tolerances and press fit allowances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 27\/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: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 59\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Headed\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H484KK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51752451604786,"sku":"H484KK","price":20.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_94f9ecf8-9ec7-4b8f-8a9c-79854640f4da.jpg?v=1788928216","url":"https:\/\/voomisupply.com\/products\/boneham-h484kk-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
