With an inside diameter of 0.238 inches (Letter designation B, Industry Code P), an outside diameter of 7\/16 inches, and an overall length of 3\/4 inches, this bushing provides consistent hole location and protects the workpiece from tool wander. Constructed from steel, it is pressed directly into a drill jig plate without a locking head, keeping the profile flush with the jig surface. Machinists, tool and die makers, and production shops use this style of bushing wherever a permanent, low-profile guide is needed.\u003c\/p\u003e\n\u003cp\u003eThis bushing suits production drilling, reaming, and boring operations in metal fabrication, toolroom, and manufacturing environments. The headless design is preferred in applications where the bushing must sit flush or where clearance above the jig plate is limited. Its press fit installation makes it a fixed, non-renewable guide intended for high-repeat operations on a single setup. It is sized to the P-series industry standard, making it a straightforward replacement in existing P-series jig plate bores of matching diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.238 inches with a tight tolerance of +0.0001 to +0.0004 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the jig plate surface, minimizing clearance requirements\u003c\/li\u003e\n  \u003cli\u003ePress fit installation creates a permanent, fixed mounting without additional hardware\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance in repetitive drilling and reaming cycles\u003c\/li\u003e\n  \u003cli\u003eMeets P-series bushing industry code standards for dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a P-series industry-standard press fit headless drill bushing for use in drill jig plates with a 7\/16-inch bore sized to accept a press fit installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolroom machinists or fixture builders using an arbor press or hydraulic press to seat the bushing flush in a prepared jig plate bore. Power down all associated machinery before pressing the bushing into the plate. Do not hammer the bushing in directly without a proper pressing tool, as this can damage the bore or distort the bushing ID. Verify bore diameter and finish in the jig plate before installation to ensure the press fit interference is within specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2380 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\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: PT2812GZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51734957130034,"sku":"PT2812GZ","price":17.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_e603b501-05b8-431f-82b2-c85b6754d45a.jpg?v=1788768550","url":"https:\/\/voomisupply.com\/products\/boneham-pt2812gz-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
