Built for right-hand cutting, it produces a controlled 0.0079-inch corner radius at the cutting edge, making it suitable for tight-tolerance bores where edge geometry consistency is critical. The bar has a minimum bore diameter of 0.2756 inches and a maximum bore depth of 1.142 inches, with an overall length of 1.772 inches. A TiCN and TiN finish coating in manufacturer grade IC228 provides wear resistance and extended tool life in a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-diameter internal boring applications in production and job-shop environments. It is well suited for CNC turning centers where consistent corner geometry and close bore tolerances are required. The solid carbide construction and dual-layer coating make it appropriate for use on steel, stainless, and cast iron workpieces under stable cutting conditions. Machinists and CNC setup technicians are the primary installers and operators of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter bores\u003c\/li\u003e\n\u003cli\u003e0.0079-inch corner radius for controlled edge geometry on finish boring passes\u003c\/li\u003e\n\u003cli\u003eTiCN and TiN dual-layer coating in grade IC228 for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC lathe toolpost orientation\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.2756 inches enables use in tight, small-diameter applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.142 inches with an overall length of 1.772 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide boring bar for small-diameter internal turning applications on CNC lathes and turning centers accepting a 7.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret or toolpost is locked before inserting or adjusting the boring bar. Confirm proper shank seating and overhang length before running any cutting program. Follow the machine tool manufacturer guidelines for tool projection limits to avoid chatter and tool deflection in small-diameter bores.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.142 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.772 inches (45.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches\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\u003eFinish Coating\u003c\/strong\u003e: TiCN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51742853890354,"sku":"6403667","price":111.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e827208d0b281460e54343653a79875e.jpg?v=1788839855","url":"https:\/\/voomisupply.com\/products\/iscar-6403667-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
