Designated as model D41-DUAL, it accommodates boring bars up to 2 inches in diameter and fits lathes with a swing range of 17 to 32 inches. The holder measures 3.5 inches in overall height and 5.5 inches in overall length, with a centerline height of 1 inch. Machinists and tool room technicians install this holder onto a compatible quick-change tool post to enable precise internal boring operations on a range of workpiece diameters.\u003c\/p\u003e\n\u003cp\u003eThis holder is suited for production and job-shop lathe setups where dual boring bar capacity is needed without tool post changeovers. It is intended for use on lathes with a swing of 17 to 32 inches, making it appropriate for mid-size engine lathes commonly found in general machining, repair shops, and manufacturing facilities. The Series DA designation identifies its tool post interface family, and the D41-DUAL configuration allows two boring bars to be staged simultaneously for efficiency on sequential operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual boring bar holder configuration for staging two bars without additional changeovers\u003c\/li\u003e\n  \u003cli\u003eAccepts boring bars up to 2 inches in diameter\u003c\/li\u003e\n  \u003cli\u003eCompatible with lathes in the 17 to 32 inch swing range\u003c\/li\u003e\n  \u003cli\u003eCenterline height of 1 inch for consistent tool alignment\u003c\/li\u003e\n  \u003cli\u003eOverall height of 3.5 inches and overall length of 5.5 inches for a compact footprint on the tool post\u003c\/li\u003e\n  \u003cli\u003eSeries DA interface for use with DA-series quick-change tool post systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Series DA quick-change tool post systems on engine lathes with a swing of 17 to 32 inches (430 to 810 mm).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tool room technician. Power down and lock out the lathe before mounting or removing any tool post holder. Secure the holder firmly to the quick-change tool post according to the post manufacturer's torque and clamping procedure before initiating any cutting operation. Verify boring bar alignment and centerline height against the workpiece centerline before beginning the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolder Number\u003c\/strong\u003e: D41-DUAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolder Type\u003c\/strong\u003e: Boring Bar Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Capacity\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLathe Swing Range\u003c\/strong\u003e: 17 to 32 inches (430 to 810 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12.65 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: DORIAN TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73310101713\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67906248147250,"sku":"73310101713","price":679.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2e85c0e31eacbe9085a14311a49c0cd.jpg?v=1791166534","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310101713-boring-bar-holder-series-da","provider":"Voomi Supply","version":"1.0","type":"link"}
