It features a 40 mm body diameter and an integral mount configuration, eliminating the need for a separate adapter and reducing runout. The bore range spans 44 mm at minimum to 56 mm at maximum, making it suited for tight-tolerance finish boring passes. Machining professionals and toolroom technicians install this head on CNC machining centers and boring mills where consistent, repeatable hole quality is required.\u003c\/p\u003e\n\u003cp\u003eThe CoroBore 825 series targets fine boring applications where dimensional accuracy and surface finish are critical. This head is used in both job shop and production environments for finishing bored holes in ferrous and non-ferrous workpieces. The integral mount design suits installations where direct spindle or toolholder attachment is preferred over modular coupling systems. It is a single-unit package intended for professional machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40 mm body diameter with integral mount for direct, low-runout installation\u003c\/li\u003e\n  \u003cli\u003eBore diameter range of 44 mm to 56 mm for fine finishing passes\u003c\/li\u003e\n  \u003cli\u003ePart of the CoroBore 825 series, engineered for precision diameter boring\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction reduces setup variables versus modular alternatives\u003c\/li\u003e\n  \u003cli\u003eWeighs 1.22 pounds, keeping spindle load minimal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit boring head for CNC machining centers and boring mills that accept integral mount tooling in the CoroBore 825 series configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring head. Follow the machine tool manufacturer torque and clamping specifications for the integral mount interface. Inspect the mounting surfaces for contamination or damage before seating the head to maintain concentricity and bore accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 56 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Integral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroBore 825\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.22 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5728239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734494642482,"sku":"5728239","price":1883.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fb9480e13ac3ec753b3fa6316155bff_4eed928a-0c54-4359-998e-03f339d72bc3.jpg?v=1788763233","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5728239-boring-head-40mm-corobore-825","provider":"Voomi Supply","version":"1.0","type":"link"}
