It is designed to guide drill bits and other cutting tools with precision in jig and fixture applications. The bushing features a 7.25-inch inside diameter and a body outside diameter of 12.00 mm, with an overall length of 20.00 mm. Constructed from steel, it provides consistent hole location and resists wear during repetitive drilling operations. Machinists, toolmakers, and fixture builders working in precision fabrication environments are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs where a fixed, non-renewable press fit style is appropriate. The headless HM profile allows it to sit flush or below the jig plate surface, making it well-suited for close-clearance setups. It is typically installed in production machining environments where repeatable hole placement is required across multiple workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for secure, permanent seating in the jig plate\u003c\/li\u003e\n  \u003cli\u003eHM industry code classification for standard headless bushing fitment\u003c\/li\u003e\n  \u003cli\u003e7.25-inch inside diameter for precise drill guide alignment\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design intended for fixed, long-term jig setups\u003c\/li\u003e\n  \u003cli\u003eHeadless profile allows flush or below-surface installation in tight clearance applications\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 HM-series drill jig and fixture applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a toolmaker or machinist using an arbor press or hydraulic press to seat the bushing into a reamed hole in the jig plate. The receiving hole should be reamed to the appropriate tolerance to achieve the correct press fit interference. Ensure the jig plate is secured and properly supported before pressing to avoid distortion. Do not use a hammer to drive the bushing, as this can damage the bushing bore or misalign the component.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 7.25 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\u003eMaterial\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: 0.37 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: AM00000253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51750793216306,"sku":"AM00000253","price":25.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0144a81945c5a5f0da59d0ebb1663df.jpg?v=1788919766","url":"https:\/\/voomisupply.com\/products\/boneham-am00000253-drill-bushing-hm-7-25-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
