Manufactured from steel, this bushing installs without a head flange, sitting flush within the jig plate for unobstructed tool travel. The inside diameter measures 20.5 inches, and the body outside diameter measures approximately 30.00 millimeters with an overall length of 36.00 millimeters. It is a non-renewable fixed bushing intended for permanent or long-service installations where the bushing is pressed directly into the drill jig or fixture body.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in production drilling jigs and fixture plates across industrial machining environments. The headless PM-style configuration is common in applications where clearance above the jig plate surface is limited or where a smooth top surface is required. Licensed machinists, tool-and-die makers, and fixture builders are the primary trades that install and service this type of tooling component. It is appropriate for both prototype and high-volume production setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method  -  no retaining ring or locking mechanism required\u003c\/li\u003e\n  \u003cli\u003eHeadless PM-style profile sits flush with jig plate surface\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design intended for fixed, long-term installations\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 20.5 inches ensures consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31171603 for procurement classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press fit headless drill bushing conforming to PM industry code standards, suitable for use in standard drill jig and fixture plates that accept press fit bushing installations of the corresponding outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by tool-and-die makers or machinist tradespeople using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The receiving bore should be machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or bore distortion. Do not hammer the bushing directly without a proper press driver. Confirm the bushing is fully seated and flush before placing the jig into service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 20.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: AM00000483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51739526398258,"sku":"AM00000483","price":25.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/334d6e0aecba5de3e24131a22fd16e69.jpg?v=1788815755","url":"https:\/\/voomisupply.com\/products\/boneham-am00000483-drill-bushing-pm-20-5-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
