Machined from steel, this bushing installs permanently into a drill jig plate via press fit — no locking collar or removal tool required. The inside diameter is 0.152 inches, corresponding to a Number 24 wire gauge drill size, with an inside diameter tolerance of plus 0.0001 to plus 0.0004 inches. The body outside diameter is 5\/16 inches and the length under the head is 3\/4 inches. This is a non-renewable bushing, meaning it is intended for fixed, long-run installations where the bushing does not need to be swapped out between operations.\u003c\/p\u003e\n\u003cp\u003eType H headed drill bushings are used in production and toolroom environments where consistent hole location is required across repeated drilling cycles. The head seats flush against the top face of the jig plate, providing a positive stop that controls the bushing depth and prevents rotation under cutting forces. Machinists, tool and die makers, and fixture builders install this bushing in steel and aluminum jig plates for drilling, reaming, and similar guided-tool operations. The headed style is preferred when back-migration of the bushing must be prevented without a secondary retention method.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — permanent seating in jig plate bore with no collar required\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.152 inches matches Number 24 wire gauge drill size\u003c\/li\u003e\n  \u003cli\u003eTight ID tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 27\/64 inches and head height of 1\/8 inch provide a positive stop against the jig plate face\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repeated-cycle production drilling fixtures\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — suited for permanent fixture installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed drill bushing for use in standard drill jig plates that accept a 5\/16-inch press fit bore, conforming to Type H industry dimensions for headed press fit bushings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by a toolmaker or machinist using an arbor press or hydraulic press — never drive with a hammer, as this can crack or misalign the bushing. The receiving bore in the jig plate should be finish-reamed to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is considered permanent and is not designed for field removal or replacement. Verify bore alignment and cleanliness before pressing to ensure proper seating and concentricity.\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: 0.152 inches (Number 24 wire gauge)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\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\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: H2012EQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730065522994,"sku":"H2012EQ","price":21.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_286f4275-cc81-4be4-ba62-242aafba225d.jpg?v=1788711109","url":"https:\/\/voomisupply.com\/products\/boneham-h2012eq-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
