Machined from steel and hardened to 60 to 65 HRC, it provides the wear resistance needed for high-repetition drilling operations. The bushing installs by pressing directly into a jig plate without locking hardware, making it a permanent or semi-permanent guide. The 0.5000-inch inside diameter carries a close tolerance of plus 0.0001 to plus 0.0005 inches, ensuring repeatable hole location accuracy. This is a component installed by tool-and-die makers, machinist trades, and production fixture builders.\u003c\/p\u003e\n\u003cp\u003eThe H648LK is suited for drill jig applications in manufacturing, fabrication, and machine shop environments. Its headed design seats flush against the jig plate surface, preventing the bushing from being pushed through under drilling load. With a body outside diameter of 1 inch and a length under head of 0.5 inches, it fits standard jig plate counterbores designed to the ANSI bushing standard. This bushing is appropriate for both prototype fixtures and production-volume tooling where consistent hole placement is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no locking collar or hardware required\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction at 60 to 65 HRC for extended wear life in high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eHeaded design resists axial push-through under drilling thrust load\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI bushing standards for interchangeability with standard jig plates\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — permanent installation intended for fixed production fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-compliant Type H press fit headed drill bushing for use in standard jig plates and fixtures requiring a 1-inch body outside diameter and 0.5-inch inside diameter tool guide.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinist or toolmaking trades using an arbor press or hydraulic press — never drive with a hammer, as this can crack the bushing or distort the bore. The receiving hole in the jig plate must be machined to the correct interference fit per ANSI standards before installation. Once pressed in, the H648LK is not intended for removal without risking damage to the bushing or plate. Verify inside diameter clearance for the intended drill or tool shank before pressing the bushing into the fixture.\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/16 inches\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\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H648LK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732841726258,"sku":"H648LK","price":21.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_c0e2b846-debb-4f73-9e4b-5c2dfa9965b6.jpg?v=1788747424","url":"https:\/\/voomisupply.com\/products\/boneham-h648lk-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
