Built from solid carbide with a TiAlN finish coating and manufactured to ISCAR grade IC908, it delivers consistent cutting performance in hardened and difficult-to-machine materials. The bar features a right-hand cutting direction, a minimum bore diameter of 0.2677 inches, and a maximum bore depth of 1.7323 inches. Overall length is 2.3622 inches with a corner radius of 0.0059 inches. Machinists and tool-room technicians working in precision boring applications will find this bar suited to tight-tolerance internal chamfer work.\u003c\/p\u003e\n\u003cp\u003eThis chamfering boring bar is intended for use in small-bore internal machining applications where access is restricted and precision geometry is required. The 7.00 mm shank diameter fits standard boring bar holders and quick-change tooling systems compatible with that shank size. Typical applications include chamfering the entry of bored holes, deburring internal edges, and producing consistent chamfer angles in production runs on CNC turning or mill-turn equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish coating improves heat resistance and tool life in dry or semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003eISCAR grade IC908 substrate suited for hardened steels and difficult alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe and CNC turning setups\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0059 inches supports sharp, controlled chamfer geometry\u003c\/li\u003e\n  \u003cli\u003eCompact 2.3622-inch overall length for use in confined boring bar holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in boring bar holders with a 7.00 mm shank bore. Verify holder clearance and minimum bore diameter capability before installation to confirm fitment with your specific tooling system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with boring bar setup and CNC tooling systems. Ensure the machine spindle is fully stopped and the turret or tool post is locked before inserting or removing the bar. Confirm the boring bar holder is clean and free of chips before seating the shank to maintain runout tolerances. Do not exceed the recommended maximum bore depth of 1.7323 inches to avoid deflection or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Chamfering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.2677 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.7323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3622 inches\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: 0.0059 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 6403848\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51729605001522,"sku":"6403848","price":129.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd3add16f3430f91d5ef6bf73407ab01.jpg?v=1788706653","url":"https:\/\/voomisupply.com\/products\/iscar-6403848-chamfering-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
