With a minimum bore diameter of 0.315 inches (8.00 mm) and an overall length of 1.378 inches (35.00 mm), this bar is built for small-bore applications where rigidity and precision are critical. The right-hand cutting direction suits standard CNC and manual lathe setups. The TiCN and TiN finish coatings, combined with ISCAR grade IC228 carbide, provide wear resistance and thermal stability during interrupted or continuous cuts in a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for use in CNC turning centers, manual lathes, and gang-tool setups where small internal diameters must be machined to close tolerances. The 7.00 mm shank diameter fits standard small-bore tooling blocks and holders. With a maximum bore depth of 0.0984 inches (2.50 mm), it is best applied to shallow internal features such as counterbores, recesses, and short through-bore finishing passes. Machinists and CNC operators in precision machining, tool rooms, and production shops are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter: 0.315 inches (8.00 mm) for small internal ID applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore work\u003c\/li\u003e\n\u003cli\u003eDual TiCN and TiN finish coating for wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eISCAR grade IC228 carbide substrate suited for a wide range of machining conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and turning center orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 7.00 mm shank boring bar holders and tooling blocks on CNC turning centers and manual lathes configured for right-hand internal boring operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tooling block is properly secured before mounting or removing the boring bar. The bar must be clamped at the correct overhang length to minimize deflection; excessive overhang beyond the shank diameter recommendation will reduce accuracy and increase chatter risk. Confirm holder bore and clamping screw torque per the tooling system manufacturer specifications before running cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.378 inches (35.00 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: 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\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: 6402760\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727734473010,"sku":"6402760","price":91.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36dd67af936848cd3bd0eb7292cb27bd.jpg?v=1788681424","url":"https:\/\/voomisupply.com\/products\/iscar-6402760-boring-bar-0-315-in-min-bore-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
