Manufactured from steel, this bushing carries industry code P and fits directly into a prepared hole without a flange or head, keeping the bushing flush with the workpiece or jig plate surface. The inside diameter is 0.052 inches, corresponding to a number 55 wire gauge drill, with a tight ID tolerance of plus 0.0001 to plus 0.0004 inches. The body outside diameter is 3\/16 inches and the overall length is 3\/4 inches. Machinists, tool and die makers, and fixture builders install this type of bushing into drill jigs to maintain hole location accuracy across repeated operations.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for precision drill jig applications in manufacturing, fabrication, and tooling environments. The headless profile makes it appropriate for installations where a recessed or flush-mount configuration is required and where a flanged head would interfere with workpiece seating. The counterbored design accommodates the press fit installation method. It is a fixed, non-renewable bushing, meaning it is intended to remain permanently installed in the jig body rather than be swapped out during production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for permanent, stable seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHeadless design provides a flush profile suitable for recessed mounting\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.052 inches matches a number 55 wire gauge drill\u003c\/li\u003e\n\u003cli\u003eID tolerance of plus 0.0001 to plus 0.0004 inches for close-tolerance tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eCounterbored body supports proper press fit engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for precision drill jigs requiring a press fit, headless, industry code P bushing with a 0.052 inch inside diameter and 3\/16 inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit drill bushings are typically installed by a machinist or toolmaker using an arbor press to seat the bushing flush into a prepared jig plate hole. Power down all associated machinery before performing any jig maintenance or bushing replacement. Verify the jig plate bore diameter matches the bushing outside diameter tolerance before pressing to avoid galling or improper fit. Once pressed in, this is a non-renewable bushing and is not intended for removal and reuse.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Gauge)\u003c\/strong\u003e: Number 55\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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\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\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PT1212BJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748704649522,"sku":"PT1212BJ","price":25.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51c1936fdb3e96adf578efd5efc8879e.jpg?v=1788897040","url":"https:\/\/voomisupply.com\/products\/boneham-pt1212bj-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
