Built from submicron-grade carbide, it delivers the wear resistance and edge stability required for tight-tolerance work in hardened and abrasive materials. The bar handles a minimum bore diameter of 2.80 mm (0.1102 inches) and a maximum bore depth of 10.00 mm (0.3937 inches), with a 4.00 mm shank diameter and a 24.00 mm overall length. A 0.0040-inch corner radius supports accurate profiling and chamfering transitions. This tool is installed by machinists and tool-and-die technicians working on CNC lathes, Swiss-type machines, and small-bore turning centers.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for small-part internal turning applications where bore diameter access is restricted. Typical use cases include precision components in medical device manufacturing, watchmaking, aerospace fasteners, and hydraulic fittings where sub-3 mm bore entry is required. The right-hand cutting direction makes it compatible with standard spindle rotation on conventional turning setups. Its compact 24.00 mm overall length suits short-overhang tooling configurations common in gang-slide and turret setups on Swiss and CNC lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for high hardness and edge retention in difficult materials\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 2.80 mm enables access to very small internal features\u003c\/li\u003e\n  \u003cli\u003eSupports boring, chamfering, and profiling operations in a single tool\u003c\/li\u003e\n  \u003cli\u003e0.0040-inch corner radius for controlled profiling and chamfer blending\u003c\/li\u003e\n  \u003cli\u003e20-degree bar end angle for clearance in tight bore geometries\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle rotation compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide boring bar for use in 4.00 mm shank toolholders and compatible small-bore turning systems where right-hand internal cutting tools are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine spindle fully stopped and the control in an e-stop or locked-out state. The 4.00 mm shank must be secured in a properly sized collet or toolholder to the toolholder manufacturer's specified clamping procedure. Confirm boring bar runout with a dial indicator before engaging the cut. Handle solid carbide tooling carefully to avoid chipping the cutting edge during setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 24.00 mm (0.9449 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar End Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Type\u003c\/strong\u003e: Boring, Chamfering, Profiling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6405294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728350806322,"sku":"6405294","price":77.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86a4990753fd8af3fbe3716381a75b7a.jpg?v=1788690591","url":"https:\/\/voomisupply.com\/products\/iscar-6405294-boring-profiling-bar-2-80mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
