Manufactured from steel, this bushing features a 0.073 inch inside diameter (wire gauge size 49) and a 3\/16 inch body outside diameter, with an overall bushing length of 3\/4 inch. The inside diameter is held to a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for applications where consistent hole location and drill guidance accuracy are required. It is a permanent, non-renewable bushing installed by press fit into the jig plate.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in production drilling, reaming, and boring jigs across metalworking, machining, and toolmaking operations. The headless design keeps the bushing flush with the jig plate surface, which is common in setups where multiple bushings are clustered or where tool clearance above the plate is limited. The counterbored feature accommodates specific fixture plate configurations. Machinists and toolmakers install this type of bushing in both prototype and high-volume production fixture setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, rigid seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eCounterbored configuration for compatible fixture plate applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable bushing intended for permanent fixture installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation press fit headless drill bushing for standard jig and fixture plates requiring a 3\/16 inch outside diameter press fit bushing with a 0.073 inch inside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists or toolmakers using an arbor press to seat the bushing flush into the jig plate bore. Power down all associated machinery before performing any fixture maintenance or bushing installation. The bushing bore and plate hole should be clean and free of burrs prior to pressing. Do not use a hammer to drive the bushing, as this can distort the bore and compromise tool guidance accuracy.\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 (Wire Gauge)\u003c\/strong\u003e: 49\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.073 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\u003eBody Outside Diameter\u003c\/strong\u003e: 3\/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\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\u003eCounterbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\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: PT1212CB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51731559317810,"sku":"PT1212CB","price":26.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_b23b9e5a-8410-4aa4-9c2f-ccfffe9b1196.jpg?v=1788732477","url":"https:\/\/voomisupply.com\/products\/boneham-pt1212cb-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
