This type P bushing installs without a head, sitting flush with or below the jig plate surface. It features a 5\/8-inch inside diameter, a 7\/8-inch body outside diameter, and a 1\/2-inch overall length. Hardness runs 60 to 65 HRC, providing the wear resistance required for high-cycle drilling operations. The inside diameter tolerance is held to a tight plus 0.0001 to plus 0.0005 inches, ensuring consistent hole location across repeated setups.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for machining and metalworking environments where repeatable hole placement is critical. It is pressed directly into a jig plate or fixture body and is not designed for field replacement during a production run. Typical applications include drill jigs used in manufacturing, toolrooms, and production machining shops. Machinists and tool and die makers select this style when a low-profile installation is required and a renewable bushing is not necessary for the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for secure, permanent seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush installation\u003c\/li\u003e\n\u003cli\u003eInside diameter: 5\/8 inches with a tolerance of plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003eBody outside diameter: 7\/8 inches, overall length: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 60 to 65 HRC for long service life\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style type P headless press fit drill bushing per ANSI standards, suitable for use in standard drill jigs and fixtures requiring a 7\/8-inch press fit bore and 5\/8-inch drill guide diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by a machinist or tool and die maker using an arbor press or hydraulic press. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not intended for removal or reuse. Always verify bore dimensions and alignment before pressing to avoid damage to the bushing or fixture.\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: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 1\/2 inch\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 Bushing\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: P568MH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51754983358770,"sku":"P568MH","price":19.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_e1e51fcd-9aec-4ffc-b22d-e9c53275f67e.jpg?v=1788950327","url":"https:\/\/voomisupply.com\/products\/boneham-p568mh-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
