It features a 0.5 inch inside diameter, a 0.75 inch outside diameter, and an overall length of 0.625 inches. Manufactured from steel and hardened to 60 to 65 HRC, this bushing resists wear during repeated drilling operations. The headless, press fit design allows it to seat flush in a drill jig plate without additional fasteners. It conforms to ANSI standards and is sold individually. Licensed machinists, tool and die makers, and fixture builders are the typical installers.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs on production lines, machine shops, and precision fabrication environments where consistent hole location is required across multiple workpieces. The 0.5 inch bore accommodates standard half-inch drill bits and is held to a close inside diameter tolerance of plus 0.0001 to plus 0.0005 inches, ensuring repeatable positional accuracy. It is a permanent, non-renewable bushing intended for long-term press fit installation in a jig plate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — seats permanently in the jig plate bore without fasteners\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with the plate surface, eliminating interference with the workpiece\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches for tight positional repeatability\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eIndustry code P identifies the press fit headless bushing series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or original installation component for ANSI-standard drill jigs and fixtures requiring a press fit headless bushing with a 0.5 inch bore and 0.75 inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by machinists or tool and die makers using an arbor press or hydraulic press. The jig plate bore should be machined to the mating tolerance specified for the bushing outside diameter before installation. Do not hammer the bushing in directly without a proper driver to avoid distorting the bore. Once pressed in, this bushing is non-renewable 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\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.5000 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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.625 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\u003eBushing Industry Code\u003c\/strong\u003e: P\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: PT4810LK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730358501682,"sku":"PT4810LK","price":17.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_966bbcb8-10df-4e0f-980a-e2a7f33c00ba.jpg?v=1788715982","url":"https:\/\/voomisupply.com\/products\/boneham-pt4810lk-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
