Manufactured from steel, this bushing features a 0.111 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0004 inches, a 1\/4 inch body outside diameter, and a 1-3\/8 inch length under the head. The headed design provides a positive stop against the jig plate surface, and the press fit installation method locks the bushing securely into the jig body without requiring a locking collar. Installed by machinists and tool-and-die professionals in production jig and fixture setups.\u003c\/p\u003e\n\u003cp\u003eThe H1622DM is suited for use in drill jig applications where repeatable hole location is critical. The counterbored design accommodates applications that require the head to seat flush or below the jig plate surface. This bushing is a permanent, non-renewable type, meaning it is pressed into the jig plate and replaced as a unit when worn. Typical applications include production machining environments where consistent hole geometry across multiple workpieces is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed press fit design provides a positive stop against the jig plate face\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production drilling and reaming applications\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eCounterbored head allows flush or recessed seating in the jig plate\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — pressed in permanently and replaced as a complete unit\u003c\/li\u003e\n  \u003cli\u003eInside diameter code #34 per standard bushing industry designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type H press fit headed drill bushing for use in drill jig plates machined to accept a 1\/4 inch body outside diameter press fit bushing per industry standard tooling practices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit drill bushings are installed by machinists using an arbor press or hydraulic press — never drive with a hammer, as this can damage the bushing bore or distort the jig plate. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, the bushing is considered permanent and is not designed for removal and reuse. Verify inside diameter and length under head against tooling requirements before pressing in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: 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 (Decimal)\u003c\/strong\u003e: 0.1110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Industry Code)\u003c\/strong\u003e: #34\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 23\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\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\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: H1622DM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51753188786482,"sku":"H1622DM","price":65.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_28912cb1-090b-4077-ac78-b6081f14459b.jpg?v=1788933670","url":"https:\/\/voomisupply.com\/products\/boneham-h1622dm-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
