Built from 1025-grade solid carbide and finished with a TiAlN\/TiN coating, this bar delivers extended tool life and thermal resistance in demanding cutting conditions. It accommodates a minimum bore diameter of 6.2mm and a maximum boring depth of 15mm, making it well suited for small-bore finish and semi-finish operations. The 6mm shank diameter fits standard small-bore toolholders, and the 37.3mm overall length keeps the tool compact and rigid. Machinists and CNC operators working in precision shops, tool rooms, and production environments will find this an effective solution for tight-tolerance internal features.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-diameter internal turning applications in metalworking environments. Its right-hand cut orientation suits standard lathe setups where the spindle rotates conventionally. The solid carbide construction handles steel, stainless steel, cast iron, and similar workpiece materials where carbide-grade tooling is specified. It is commonly used in job shops, aerospace component machining, and general precision turning where bore diameters in the sub-10mm range are required and where deflection control is critical to achieving finish and tolerance targets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1025-grade solid carbide construction for rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eTiAlN\/TiN PVD coating improves thermal hardness and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e6.2mm minimum bore diameter enables machining of very small internal features\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003e6mm shank diameter for compatibility with common small-bore toolholding systems\u003c\/li\u003e\n\u003cli\u003eCompact 37.3mm overall length minimizes overhang and reduces vibration tendency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement boring bar for CNC lathes and turning centers equipped with 6mm shank toolholders requiring right-hand-cut internal turning tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the boring bar from the toolholder. Ensure the shank is clamped to the full recommended gripping length to minimize overhang and tool deflection. Do not exceed the tool manufacturer's recommended cutting parameters for this bar size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 6.2mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Boring Depth\u003c\/strong\u003e: 15mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 37.3mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 1025 Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5726643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749742772530,"sku":"5726643","price":106.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b454f2daa8cc3b6d6ac54d12abd0546.jpg?v=1788909824","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5726643-boring-bar-6-2mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
