With an inside diameter of 0.234 inches and a body outside diameter of 7\/16 inches, this bushing provides accurate drill alignment during repetitive production operations. The overall bushing length is 5\/16 inches. Constructed from steel, the PT285GW delivers the hardness and wear resistance required for sustained use in metal fabrication and machining environments. It carries industry code P and features an inside diameter tolerance of +0.0001 to +0.0004 inches. Machinists and tool-and-die professionals install this component when setting up drill jigs for consistent hole location.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for production drilling, reaming, and boring operations where a fixed, non-renewable liner is acceptable. The headless profile allows flush seating within a jig plate without the need for a counterbore or lock collar. It is appropriate for applications in metal fabrication shops, machine shops, and light manufacturing facilities. The press fit installation method means the bushing seats permanently in the jig plate bore with no additional hardware required, making it a straightforward choice for dedicated, high-run fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no lock ring or collar required for permanent seating\u003c\/li\u003e\n  \u003cli\u003eHeadless design seats flush with jig plate surface\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance in production environments\u003c\/li\u003e\n  \u003cli\u003eIndustry code P designation for standardized bushing selection and replacement\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed liner suitable for dedicated high-volume fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed liner for standard drill jig plates requiring a press fit headless bushing with a 0.234 inch inside diameter and a 7\/16 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool-and-die technicians using an arbor press or hydraulic press to seat the bushing flush into a properly sized jig plate bore. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing to avoid bushing damage or misalignment. Once pressed in, this bushing is not designed for removal or reuse. Deburr and clean the jig plate bore prior to installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.234 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Designation\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 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: 5\/16 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\u003eMaterial\u003c\/strong\u003e: Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: PT285GW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51735672357170,"sku":"PT285GW","price":15.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_9a039e93-e2f7-44e5-93ff-3fa4b6e6dfb7.jpg?v=1788773564","url":"https:\/\/voomisupply.com\/products\/boneham-pt285gw-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
