It is designed to guide drill bits and boring tools with precision in jig and fixture applications. The bushing installs without a head flange, allowing a flush or sub-flush installation in drill jig plates. With an inside diameter of 7.5 inches and a body outside diameter of approximately 0.472 inches, this bushing provides accurate tool guidance and resists wear over repeated drilling cycles. Machinists, toolmakers, and production technicians are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and production tooling where repeatable hole location accuracy is required. The headless design is appropriate when a flush surface is needed on the jig plate, or when vertical clearance is limited. The HM series designation follows standard bushing industry coding, making it straightforward to cross-reference with jig and fixture design specifications. Both prototype shops and high-volume production environments use this style of bushing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for secure, permanent seating in the jig plate\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush mounting where head clearance is limited\u003c\/li\u003e\n\u003cli\u003eHM industry code series for easy cross-referencing in fixture design\u003c\/li\u003e\n\u003cli\u003eSteel construction provides wear resistance and dimensional stability under repeated tool passes\u003c\/li\u003e\n\u003cli\u003eNon-renewable design — intended as a fixed, permanent bushing installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation bushing for drill jig fixtures requiring an HM-coded press fit headless drill bushing with a 7.5-inch inside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit drill bushings are typically installed by toolmakers or machinist personnel using an arbor press or hydraulic press. The jig plate bore must be machined to the appropriate interference fit tolerance before pressing the bushing in place. Do not hammer the bushing directly without a proper driver to avoid deformation of the bushing bore. Verify bore alignment and cleanliness before installation to ensure accurate tool guidance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7.5 inches\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\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: 0.37 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: AM00000263\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744642662706,"sku":"AM00000263","price":21.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c642ef111582f8aabe3b84110edc8197_f9c24343-7dfd-4ecf-b32b-749a033e7ce4.jpg?v=1788859375","url":"https:\/\/voomisupply.com\/products\/boneham-am00000263-hm-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
