Classified under industry code HM, this bushing provides a hardened guide surface that controls drill bit alignment and reduces wander during precision hole operations. The inside diameter measures 3.9 inches, with a body outside diameter of approximately 0.276 inches (7.00 mm) and an overall length of approximately 0.472 inches (12.00 mm). Constructed from steel, it is suited for repetitive production drilling where consistent hole placement is required. Installation and replacement are handled by toolmakers, machinists, and fixture builders.\u003c\/p\u003e\u003cp\u003eThis bushing is applied in jig and fixture setups across metalworking, woodworking, and general manufacturing environments. Its headless profile allows the bushing to sit flush with the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece clamping or part travel. It is not a renewable bushing, meaning it is pressed directly into the jig plate bore and is intended as a fixed installation rather than a slip-renewable or lock-renewable type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method for secure, flush-mount seating in jig plates\u003c\/li\u003e\n\u003cli\u003eHM industry code classification for standardized sizing and sourcing\u003c\/li\u003e\n\u003cli\u003e3.9 inch inside diameter for drill bit guidance and alignment control\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eHeadless design eliminates flange interference with workpieces or clamps\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed-installation type for permanent fixture integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a fixed press fit drill bushing for use in machined jig plates and fixture bodies where an HM-series headless bushing with a 3.9 inch inside diameter is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by machinists or toolmakers using an arbor press or hydraulic press to drive the bushing flush into a precision-reamed bore. Power to any associated machinery should be locked out before jig maintenance or bushing replacement. The receiving bore diameter must match the bushing outside diameter tolerance to ensure proper retention without distortion of the guide bore. Do not hammer bushings directly without a proper driver to avoid damage to the bushing or plate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 7.00 mm (approximately 0.276 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 12.00 mm (approximately 0.472 inches)\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: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: AM00000134\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51735582048562,"sku":"AM00000134","price":23.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b639d225100d9e382f95bb8f0770292c.jpg?v=1788773115","url":"https:\/\/voomisupply.com\/products\/boneham-am00000134-press-fit-headless-drill-bushing-hm","provider":"Voomi Supply","version":"1.0","type":"link"}
