Assigned Industry Code P, this bushing features a 0.246 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate tool guidance and repeatable hole placement. The 7\/16 inch outside diameter allows for secure press fit installation into a drill jig or fixture plate without the need for a head flange. Constructed from steel, the CB00001113 is suited for production environments where consistent, high-cycle tooling accuracy is required. Machinists, toolmakers, and jig builders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in fixed drill jig applications where the bushing is not intended to be removed or replaced during a production run. The headless design keeps the bushing flush with or below the jig plate surface, making it appropriate for close-clearance setups and multi-station fixtures in both job shop and production machine shop environments. With a 1 inch overall length, it provides sufficient tool guidance depth for standard drilling and reaming passes. It is not a renewable bushing, meaning it is pressed in permanently for the life of the jig or until the jig plate is reworked.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no retaining ring or locking mechanism required\u003c\/li\u003e\n  \u003cli\u003eHeadless design for flush or sub-flush mounting in jig plates and fixture blocks\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in high-cycle machining applications\u003c\/li\u003e\n  \u003cli\u003eIndustry Code P designation for cross-reference compatibility with standard bushing specifications\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — intended as a permanent press fit installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard P-series press fit headless drill bushing for use in drill jigs and machining fixtures requiring a 0.246 inch bore and 7\/16 inch OD press fit seat.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly sized hole in the jig plate. The mating bore in the jig plate should be machined to the appropriate interference fit tolerance for the 7\/16 inch OD before installation. Do not hammer the bushing in directly without a press driver to avoid distorting the bore. Once pressed in, this bushing is not intended for removal — rework of the jig plate is required if replacement becomes necessary.\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\u003eInside Diameter (Decimal Inch)\u003c\/strong\u003e: 0.246 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: D\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: 1 inch\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: CB00001113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51752963506482,"sku":"CB00001113","price":22.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53960af1994fcb3ec5bf7694aa985f94.jpg?v=1788931602","url":"https:\/\/voomisupply.com\/products\/boneham-cb00001113-headless-drill-bushing-p-0-246-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
