Built to ANSI standards, this Type P bushing features a 31\/64 inch inside diameter, a 3\/4 inch body outside diameter, and a 5\/8 inch overall length. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations in production environments. Machinists and toolmakers install this bushing directly into drill jig plates, where it maintains accurate hole location across high-cycle runs without a locking collar or head flange.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling setups found in machine shops, metal fabrication facilities, and manufacturing production lines. The headless profile allows it to sit flush with or below the jig plate surface, making it appropriate for applications where a flanged head would interfere with workpiece clearance or chip flow. It is a non-renewable bushing, meaning it is pressed permanently into the jig plate and is not intended for field replacement during a production run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation for permanent, secure seating in drill jig plates\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the jig surface for unobstructed workpiece access\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 +0.0001 to +0.0005 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for Type P drill bushing geometry\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design for permanent fixture installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation Type P headless press fit drill bushing for use in standard ANSI-compliant drill jig plates and tooling fixtures requiring a 3\/4 inch outside diameter bushing seat.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a precision-bored jig plate hole. The mating bore in the jig plate must be held to the appropriate interference fit tolerance to achieve proper retention. Do not hammer the bushing in directly without a press tool, as this can damage the bushing bore or distort the jig plate. Verify all drill press or machine spindle power is off and the fixture is secure before beginning installation or inspection.\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 31\/64 inches\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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 5\/8 inches\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\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: PT4810LG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51747338780978,"sku":"PT4810LG","price":17.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_e4f0a1ec-3db4-4b4f-bce2-f23082e97b7c.jpg?v=1788878786","url":"https:\/\/voomisupply.com\/products\/boneham-pt4810lg-headless-drill-bushing-31-64-id-3-4-od","provider":"Voomi Supply","version":"1.0","type":"link"}
