Built to Bushing Industry Code P, this bushing features a 0.8125 inch (13\/16 inch) inside diameter, a 1-3\/8 inch outside diameter, and a 3\/4 inch overall length. Constructed from hardened steel at 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations in production jig and fixture setups. The headless design allows flush installation in tight clearance environments where a flanged head is not practical.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and tooling plates across manufacturing, fabrication, and machine shop environments. The press fit installation method means the bushing is driven permanently into a prepared hole in the jig plate — no liner bushing is required. It is a fixed, non-renewable style appropriate for high-volume production runs where the bushing remains in place for the life of the fixture. Machinists, tool and die makers, and fixture builders are the typical installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBushing Industry Code P — standardized sizing for direct interchangeability in ANSI-compliant tooling\u003c\/li\u003e\n\u003cli\u003e0.8125 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for consistent drill guidance\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch body outside diameter for secure press fit retention in the jig plate\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 60 to 65 HRC for extended tool life under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eHeadless profile allows flush or sub-flush installation in space-constrained fixtures\u003c\/li\u003e\n\u003cli\u003eNon-renewable, permanent installation style — ideal for dedicated high-volume drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-standard press fit headless drill bushing for use in drill jigs and machining fixtures requiring a Bushing Industry Code P bushing with a 13\/16 inch inside diameter and 1-3\/8 inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by a machinist or tool and die maker using an arbor press or hydraulic press into a precisely reamed hole in the jig plate. The receiving hole must be machined to the correct interference fit tolerance per ANSI standards before installation. Once pressed in, this bushing is not intended for removal or replacement. Always ensure the fixture is secured and de-energized from any automated equipment before pressing the bushing into position.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13\/16 inches (0.8125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1-3\/8 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\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\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\u003eStandards\u003c\/strong\u003e: ANSI\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: P8812NM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51753095725362,"sku":"P8812NM","price":23.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_53448550-d349-4d59-9d2d-d6674ec522dc.jpg?v=1788932758","url":"https:\/\/voomisupply.com\/products\/boneham-p8812nm-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
