It is designed to guide drill bits with precision during machining operations, maintaining accurate hole location and reducing tool wander in jig and fixture applications. The bushing features an inside diameter of 8.25 inches, a body outside diameter of 15.00 millimeters, and an overall length of 12.00 millimeters. Constructed from steel, it delivers the hardness and wear resistance required for repetitive production drilling. This bushing is installed by pressing directly into a mating hole in a drill jig plate, providing a fixed, non-renewable guide for sustained drilling cycles.\u003c\/p\u003e\n\u003cp\u003ePress fit headless drill bushings of this type are commonly used in industrial machining, metalworking, and precision fabrication environments. They are suited for drill jig plates where a flush, headless profile is required to avoid interference with workpiece surfaces or clamping fixtures. The HM industry code designation identifies a specific dimensional standard recognized across tooling and jig-building applications. Machinists and toolmakers working with production jigs, transfer fixtures, and repetitive hole-locating operations will find this bushing appropriate for both short-run and sustained production use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no fasteners or locking collars required\u003c\/li\u003e\n  \u003cli\u003eHeadless design provides a flush profile for unobstructed workpiece contact\u003c\/li\u003e\n  \u003cli\u003eHM industry code designation ensures dimensional conformance to standard jig bushing specifications\u003c\/li\u003e\n  \u003cli\u003eSteel construction delivers hardness and wear resistance for repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing suitable for high-volume production jig applications\u003c\/li\u003e\n  \u003cli\u003e8.25-inch inside diameter guides tooling with consistent positional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard HM-code press fit headless drill bushing for use in drill jig plates and fixture bodies requiring a fixed, non-renewable bushing with an 8.25-inch inside diameter bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolmaker using an arbor press or hydraulic press to seat the bushing flush into a precisely reamed jig plate bore. The mating hole in the jig plate must be machined to the correct interference fit tolerance for the bushing outside diameter before pressing. Do not drive the bushing with impact tools, as this can cause distortion or cracking of the bushing or jig plate. Verify bore alignment before pressing to prevent cocking or uneven seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 8.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 15.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 12.00 millimeters\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\u003eBushing Industry Code\u003c\/strong\u003e: HM\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: 0.5 pounds\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: AM00000287\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748916789554,"sku":"AM00000287","price":20.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c642ef111582f8aabe3b84110edc8197_029e25b7-b82e-42f9-887e-74a10bb70de3.jpg?v=1788900075","url":"https:\/\/voomisupply.com\/products\/boneham-am00000287-drill-bushing-hm-8-25-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
