It features a 0.5-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 0.75-inch body outside diameter, and a 0.625-inch length under the head. The 0.875-inch head outside diameter and 0.125-inch head height allow the bushing to seat flush against a jig plate surface. This style is a permanent, non-renewable installation intended for production drilling, reaming, and boring operations where consistent hole location is required. Machinists, toolmakers, and fixture builders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe H4810LK is suited for press fit installation into drill jig plates and tooling fixtures in both job shop and production manufacturing environments. The headed design prevents the bushing from being pushed through the jig plate during use, making it appropriate for applications where thrust forces are a concern. It is used wherever a permanent, non-renewable drill bushing with a 0.5-inch bore is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, non-renewable jig plate seating\u003c\/li\u003e\n  \u003cli\u003eType H headed design resists axial push-through under drilling thrust loads\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive production drilling cycles\u003c\/li\u003e\n  \u003cli\u003e0.875-inch head outside diameter with 0.125-inch head height for low-profile seating\u003c\/li\u003e\n  \u003cli\u003eNon-counterbored body for straightforward press fit installation\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 and tooling fixtures requiring a Type H press fit headed bushing with a 0.5-inch inside diameter and 0.75-inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinist personnel using an arbor press or hydraulic press to drive the bushing into a properly sized jig plate bore. The receiving bore in the jig plate must be machined to the correct interference fit dimensions before installation. Do not strike the bushing directly with a hammer, as this can damage the head seating surface or distort the inside diameter. Once pressed in, this bushing is not designed for removal and reuse.\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.5 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: H4810LK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732513718578,"sku":"H4810LK","price":21.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4019ca3c0ffe1cf57b9878b30836286f.jpg?v=1788743837","url":"https:\/\/voomisupply.com\/products\/boneham-h4810lk-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
