Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers the wear resistance required for repetitive drilling operations. The inside diameter is 7.6 inches, with a body outside diameter of 12.00 mm and an overall bushing length of 20.00 mm. It is installed by pressing directly into a jig plate without a head flange, keeping the bushing flush with the plate surface. Machinists and tool-and-die professionals rely on this type of bushing for consistent hole location across production runs.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and fixtures in production machining environments, both in job shops and manufacturing facilities. It is a non-renewable bushing, meaning it is pressed permanently into the jig plate rather than being designed for routine field replacement. Typical applications include guiding standard twist drills and reamers where tight positional tolerances are required. The HM designation follows ANSI standards, making it a direct fit in tooling designed to that specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for secure, permanent seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHM industry code classification per ANSI standards\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.005\/+0.014 mm for precise drill guidance\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with jig plate surface\u003c\/li\u003e\n\u003cli\u003eNon-renewable bushing intended for permanent installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-conforming HM-classification press fit headless drill bushing for use in standard drill jigs and fixtures requiring a permanently installed, flush-mount guide bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolmaker using an arbor press to seat the bushing flush into a prepared jig plate bore. Verify bore diameter and finish before pressing to avoid bushing damage or improper fit. Once pressed in, this bushing is not designed for removal and reuse. Ensure the jig plate is properly supported during installation to prevent distortion.\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: 7.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (mm)\u003c\/strong\u003e: 7.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.005\/+0.014 mm\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\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: AM00000268\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51751394312498,"sku":"AM00000268","price":34.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_2824387e-7636-4931-b784-b6f37da31d3a.jpg?v=1788923200","url":"https:\/\/voomisupply.com\/products\/boneham-am00000268-drill-bushing-hm-7-6-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
