It is designed to guide drill bits and similar cutting tools with precision during machining and fabrication operations. The bushing features a 14.5-inch inside diameter and a steel construction that resists wear under repeated drilling cycles. Press fit installation means the bushing seats directly into a drill jig or fixture plate without a retaining flange or locking collar. Licensed machinists, toolmakers, and precision fabricators install this type of bushing in production jigs where a low-profile, flush-mount bushing is required for close-tolerance work.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling setups across general machining, metalworking, and industrial fabrication environments. The headless HM-code design is a recognized standard in jig bushing applications where the bushing must sit flush with the jig plate surface. It is appropriate for both prototype shops and production-run tooling where consistent hole location accuracy is critical. The steel body provides durability in high-cycle drilling applications on metal workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation seats bushing securely into jig plate without additional hardware\u003c\/li\u003e\n\u003cli\u003eHeadless HM industry code design for flush, low-profile mounting\u003c\/li\u003e\n\u003cli\u003e14.5-inch inside diameter for precise drill bit guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eNon-renewable design for permanent fixture installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for drill jigs and fixture plates requiring HM-code press fit headless drill bushings with a 14.5-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 into a prepared bore in the jig plate. The receiving bore must be machined to the specified press fit tolerance before installation. Do not drive the bushing with a hammer directly on the bore face, as this may damage the bushing or distort the seating surface. Always verify inside diameter clearance against the intended drill or cutting tool before pressing the bushing into the fixture.\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: 14.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal Inch)\u003c\/strong\u003e: 14.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 22.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\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: 0.62 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: AM00000040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51731472056626,"sku":"AM00000040","price":27.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c642ef111582f8aabe3b84110edc8197_495d8e83-09b3-4dff-9c62-d24802cb5418.jpg?v=1788731500","url":"https:\/\/voomisupply.com\/products\/boneham-am00000040-press-fit-headless-drill-bushing-hm","provider":"Voomi Supply","version":"1.0","type":"link"}
