It is designed to guide drill bits with precision during machining and metalworking operations. The bushing features a 7.4-inch inside diameter and is manufactured from steel for durability in production and tooling environments. The headless design allows the bushing to sit flush with the jig plate surface, making it well suited for applications where a protruding flange would interfere with workpiece positioning. Machinists, toolmakers, and fixture builders are the primary installers of this component in drill jig assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jig and fixture applications across manufacturing and fabrication settings. It is pressed directly into a hardened or unhardened jig plate to provide consistent hole location and guidance for cutting tools. The PM industry code designates it as a standardized press fit headless style, commonly specified on engineering drawings for production drilling operations. It is suitable for both low-volume prototype work and higher-volume production runs where repeatable hole placement is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method — seats securely in the jig plate without fasteners\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface for unobstructed workpiece contact\u003c\/li\u003e\n  \u003cli\u003ePM industry code designation for standardized specification and interchangeability\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability during drilling\u003c\/li\u003e\n  \u003cli\u003eNon-renewable bushing — intended as a permanent installation in the jig plate\u003c\/li\u003e\n  \u003cli\u003eCompact overall bushing length of 10.00 millimeters suits thin jig plate configurations\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 drill jig and fixture assemblies where a PM-coded bushing with a 7.4-inch inside diameter is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or toolmaker using an arbor press or hydraulic press to drive the bushing into a precisely reamed hole in the jig plate. The receiving hole should be reamed to the appropriate interference fit tolerance before pressing to avoid distortion of the bushing bore. Always verify inside diameter alignment after pressing to confirm the bore has not closed beyond tolerance. Do not hammer the bushing in directly without a proper pressing tool, as this can damage the bushing or misalign it in the plate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: PM\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: 7.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 10.00 millimeters\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\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: AM00000667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51727334637874,"sku":"AM00000667","price":19.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b10a6d4d9beb819fa8ae29d5ad0242ce.jpg?v=1788676438","url":"https:\/\/voomisupply.com\/products\/boneham-am00000667-drill-bushing-pm-7-4-inch-id","provider":"Voomi Supply","version":"1.0","type":"link"}
