Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing is pressed directly into a drill jig plate without a head flange, providing a flush, low-profile installation. The inside diameter is 3.25 mm with a tolerance of +0.004 to +0.012 mm, ensuring consistent hole location accuracy during production drilling, reaming, or boring operations. This part is a permanent, non-renewable bushing intended for high-volume or fixed tooling setups.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and production fixtures across metalworking, fabrication, and precision machining environments. It is appropriate for both light manufacturing and industrial toolroom applications where repeatable hole location is critical. The HM industry code designates it as a headless press fit style, which is commonly specified by tooling engineers and machinists when a flush outer surface is required on the jig plate. Installation is typically performed by toolmakers or fixture builders in machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHM industry code press fit headless design for flush jig plate installation\u003c\/li\u003e\n\u003cli\u003eSteel construction with 60 to 65 HRC hardness for wear resistance and long service life\u003c\/li\u003e\n\u003cli\u003e3.25 mm inside diameter with tight tolerance of +0.004 to +0.012 mm for accurate tool guidance\u003c\/li\u003e\n\u003cli\u003e6.00 mm body outside diameter and 12.00 mm overall bushing length\u003c\/li\u003e\n\u003cli\u003eNon-renewable, permanent press fit installation — no head flange or locking collar required\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation press fit headless drill bushing conforming to ANSI HM industry standards, suitable for standard drill jig plates dimensioned to accept a 6.00 mm outside diameter press fit bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by toolmakers or machineists using an arbor press or hydraulic press — never drive them in with a hammer, as this can crack the bushing or damage the jig bore. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is considered permanent and is not designed for removal and reuse. Follow applicable shop safety procedures and ensure the fixture is fully secured before pressing the bushing into position.\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: 3.25 mm (3.2500 decimal inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.004 \/ +0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\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: 0.25 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: AM00000107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733764178226,"sku":"AM00000107","price":35.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_d3334024-20e1-45b8-b5f3-230d0c6ec883.jpg?v=1788759017","url":"https:\/\/voomisupply.com\/products\/boneham-am00000107-drill-bushing-hm-3-25mm-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
