It produces a 0.0315-inch corner radius and handles a minimum bore diameter of 0.315 inches with a maximum bore depth of 0.1181 inches. The right-hand cutting direction suits standard spindle rotation setups. A TiAlN and TiN dual finish coating improves wear resistance and heat dissipation during high-speed cuts. Manufactured to ISCAR grade IC1008, this bar is suited for machining a broad range of workpiece materials including steel, stainless steel, and cast iron at moderate to high cutting speeds.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for precision internal bore work in small-diameter applications on production lathes and live-tooling setups. The compact overall length of 1.0236 inches and 7.00 mm shank diameter make it well suited for tight-clearance bores in complex turned components. Machinists and CNC operators working on hydraulic valve bodies, medical components, automotive parts, and other tight-tolerance turned parts will find this bar appropriate for finishing passes where corner geometry control is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eTiAlN and TiN dual finish coating for extended tool life and thermal protection\u003c\/li\u003e\n  \u003cli\u003e0.0315-inch corner radius for consistent, repeatable fillet geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003eISCAR grade IC1008 substrate optimized for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompact 1.0236-inch overall length fits tight-clearance bore configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style solid carbide boring bar for CNC lathes and machining centers requiring a 7.00 mm shank diameter and a minimum bore diameter of 0.315 inches.

Ensure the machine spindle is fully stopped and the control is in E-stop or lockout\/tagout condition before changing tooling. Seat the shank fully in the toolholder and torque set screws to the toolholder manufacturer specification. Verify bore diameter clearance and corner radius requirements against the part print before running the first pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.0236 inches (26.00 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\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: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC1008\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728087154994,"sku":"6403930","price":94.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b5a31374ea09fbeda4b757ff41721e.jpg?v=1788687694","url":"https:\/\/voomisupply.com\/products\/iscar-6403930-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
