This bushing carries an industry code of P and features an inside diameter (ID) of 0.272 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring consistent hole location and accurate tool guidance. The body outside diameter is 7\/16 inches and the overall length is 3\/4 inches. Constructed from steel, the PT2812HS delivers the hardness and wear resistance required for repeated drilling cycles. It is a non-renewable, headless design installed via press fit into a drill jig or fixture plate.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling setups found in manufacturing, metalworking, and precision machining environments. The headless profile allows flush installation where protruding flanges would interfere with workpiece positioning or clamping. Machinists, tool-and-die makers, and fixture builders specify this type of bushing when a permanent, low-profile guide is needed for high-repetition drilling operations on production or prototype work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation for permanent, secure seating in jig or fixture plate\u003c\/li\u003e\n  \u003cli\u003eHeadless design provides flush, low-profile fit where flange clearance is limited\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches ensures precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists wear during repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eIndustry code P for straightforward cross-reference and replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design intended for permanent fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit option for press fit headless drill bushings meeting industry code P specifications with a 0.272 inch ID and 7\/16 inch OD.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the prepared bore of a drill jig or fixture plate. The receiving bore must be machined to the appropriate press fit tolerance to achieve correct interference. Do not hammer the bushing in with impact tools, as this can damage the bushing bore or distort the fixture. Verify ID clearance with the intended drill or tool shank before final installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 7\/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\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\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\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: PT2812HS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746363408690,"sku":"PT2812HS","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_d7578fc0-f1a7-41c7-9f64-caf4a4cdf742.jpg?v=1788868989","url":"https:\/\/voomisupply.com\/products\/boneham-pt2812hs-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
