Manufactured from steel, this bushing features an inside diameter of 4.7 inches, a body outside diameter of 8.00 millimeters, and an overall length of 12.00 millimeters. It installs without a head flange, seating flush with the jig plate surface via an interference press fit. Machinists and tooling specialists use this bushing in drill jigs to maintain accurate hole location and extend the service life of the jig. The non-renewable design means it is installed permanently into the jig body.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for production and maintenance machining environments where consistent hole placement is required. Its headless profile makes it appropriate for applications where a flush or recessed bushing surface is needed, such as close-tolerance jig plates used in metal fabrication shops, aerospace component machining, and general manufacturing. The PM industry code designation identifies it within the standard pressed bushing classification used across the tooling industry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method seats the bushing securely without fasteners or locking collars\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with the jig plate surface for unobstructed tool approach\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003ePM industry code classification ensures dimensional conformance to recognized tooling standards\u003c\/li\u003e\n\u003cli\u003eNon-renewable configuration suited to permanent jig setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install drill bushing for standard PM-code press fit jig plate applications in metalworking and machining environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a pre-reamed jig plate bore. The jig plate bore must be machined to the correct interference fit tolerance before installation to ensure proper retention. Once pressed in, the bushing is not intended to be removed and reused. Verify all dimensions and fitment before pressing, as forcing an incorrectly sized bushing can damage the jig plate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 8.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 12.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: AM00000573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733309325618,"sku":"AM00000573","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85c709ec1062d884911f3f1198db5cba_a0154a0c-edda-42b3-9454-6557d0113cc3.jpg?v=1788753983","url":"https:\/\/voomisupply.com\/products\/boneham-am00000573-drill-bushing-pm-4-7-inch-id","provider":"Voomi Supply","version":"1.0","type":"link"}
