Built to HM industry standards, this bushing features a 7.3-inch inside diameter and is machined from steel for durability under repeated use. It installs without a retaining head, seating flush with the jig plate for low-profile applications. Machinists and toolmakers use this type of bushing to maintain accurate hole location and protect drill jig fixtures from wear. The headless design is common in production environments where the bushing must sit below or flush with the fixture surface.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jig fixtures across industrial machining, fabrication shops, and production tooling environments. The press fit installation method means it is driven directly into the jig plate bore without additional hardware. It is appropriate for applications where a fixed, non-renewable bushing is acceptable for the production run. The HM designation identifies the body outside diameter and length to industry-standard dimensions, allowing direct interchangeability with other HM-coded bushings from compatible suppliers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHM industry code for standardized interchangeability with compatible drill jig bushings\u003c\/li\u003e\n\u003cli\u003ePress fit installation — no retaining flange or locking hardware required\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eHeadless design seats flush or below jig plate surface\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing suitable for dedicated production tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit option for HM-coded press fit headless drill jig bushings in standard tooling plate applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press to drive the bushing into a precision-reamed hole in the jig plate. The receiving bore must be machined to the correct interference fit tolerance for the HM outside diameter before pressing. Do not hammer the bushing directly without a proper pressing tool, as this can cause misalignment or damage to the bushing bore. Once pressed in, this bushing is not intended for removal and reinstallation.\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\u003eInside Diameter\u003c\/strong\u003e: 7.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 20.00 mm\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 Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 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: AM00000259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730377834802,"sku":"AM00000259","price":25.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c642ef111582f8aabe3b84110edc8197_89f8b56e-aca2-4bc5-aa6f-cf8ec7bb9ccd.jpg?v=1788716357","url":"https:\/\/voomisupply.com\/products\/boneham-am00000259-press-fit-headless-drill-bushing-hm","provider":"Voomi Supply","version":"1.0","type":"link"}
