This bushing is designed to be permanently pressed into a jig plate, providing a hardened, precise guide for drill bits during production drilling operations. With an inside diameter of 21.5 inches, a body outside diameter of 30.00 millimeters, and an overall bushing length of 36.00 millimeters, it is sized for applications requiring accurate hole location and repeatable positioning. Machinists and tooling professionals install this component in drill jigs to maintain consistent hole alignment across high-volume part runs.\u003c\/p\u003e\u003cp\u003eThis drill bushing is suited for use in precision drilling jigs and fixtures in manufacturing and fabrication environments. Because it is a headless style, it sits flush with or below the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece clearance or clamping. It is a non-renewable type, meaning it is intended as a permanent installation within the jig body rather than a removable liner system. Typical use cases include metalworking shops, toolrooms, and production floors where consistent drill guidance is required across repeated operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for permanent, secure seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHeadless HM industry code profile — flush-mount design eliminates flange interference\u003c\/li\u003e\n\u003cli\u003eSteel construction provides hardness and wear resistance for repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003e21.5-inch inside diameter guides drill bits with precise, repeatable hole location\u003c\/li\u003e\n\u003cli\u003eNon-renewable design suited for permanent fixture builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for drill jig assemblies requiring a press fit headless bushing conforming to HM industry code dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit drill bushings are typically installed by toolmakers or machinist trades using an arbor press or hydraulic press to seat the bushing flush and square within the jig plate bore. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Never drive the bushing in with a hammer, as this can distort the inner bore or crack the jig plate. Once pressed in, the bushing is not intended to be removed or replaced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: HM\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: 21.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 30.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 36.00 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: AM00000096\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733335245106,"sku":"AM00000096","price":56.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/183298a76636609fd56e8dbe7195b92c.jpg?v=1788754363","url":"https:\/\/voomisupply.com\/products\/boneham-am00000096-hm-press-fit-drill-bushing-21-5in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
