Manufactured from steel and hardened to 60 to 65 HRC, this bushing provides long service life under repeated drilling cycles. The inside diameter is 6.3 inches with a tolerance of +0.005\/+0.014 mm, ensuring consistent hole location accuracy. Machinists, toolmakers, and production engineers rely on this type of bushing as a fixed liner in drilling jigs where tool guidance must remain repeatable across high-volume operations.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jig plates and fixture bodies in both production and maintenance machining environments. The headless design allows the bushing to sit flush within the jig plate, making it appropriate for applications where a protruding flange would interfere with workpiece contact or clamping. The press fit installation method means no secondary locking hardware is required once the bushing is seated. It is not renewable, so it is intended for permanent installation in fixed-location tooling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHM industry series headless drill bushing for permanent press fit installation\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended tool life\u003c\/li\u003e\n\u003cli\u003eInside diameter of 6.3 inches with tight tolerance of +0.005\/+0.014 mm for accurate tool guidance\u003c\/li\u003e\n\u003cli\u003eFlush headless profile suits applications where flange clearance is limited\u003c\/li\u003e\n\u003cli\u003eNon-renewable design for fixed, high-repeat jig and fixture use\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for drilling jigs and fixtures requiring an HM series press fit headless bushing with a 6.3-inch inside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush and square within the jig plate bore. Ensure the jig plate bore is machined to the correct interference fit tolerance before pressing the bushing in place. Once installed, this bushing is not intended to be removed or replaced. Follow applicable shop safety procedures and use appropriate eye protection when pressing components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Series\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: 6.3 inches\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: 10.00 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\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable\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: AM00000221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736397840690,"sku":"AM00000221","price":21.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_7ee2ed76-3a53-4820-a03a-1b1cb4ef1afa.jpg?v=1788777722","url":"https:\/\/voomisupply.com\/products\/boneham-am00000221-drill-bushing-hm-6-3-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
