Manufactured from submicron solid carbide with a TiAlN and TiN finish coating, this bar delivers hardness and thermal resistance suited for demanding cutting applications. It accepts a minimum bore diameter of 0.0984 inches and reaches a maximum bore depth of 0.6299 inches. The 20-degree bar end angle and 0.002-inch corner radius make it well-suited for controlled chamfer geometry. With an overall length of 1.1811 inches and a 4.00 mm shank diameter, it fits compact tooling setups. The IC908 manufacturer grade indicates suitability for high-performance cutting conditions in production environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in CNC turning centers and small-bore machining applications where internal chamfering or angular cutting is required. The right-hand cutting direction suits standard spindle rotation on most lathes and turning centers. Its compact dimensions make it appropriate for micro-boring and small-component work common in precision machining shops, medical device manufacturing, and aerospace component production. Machinists and CNC operators working with tight bore tolerances will find the submicron carbide construction beneficial for maintaining edge integrity over extended runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN and TiN dual finish coating for thermal protection and extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.0984 inch minimum bore diameter enables work on very small internal features\u003c\/li\u003e\n  \u003cli\u003e20-degree bar end angle provides precise chamfer geometry control\u003c\/li\u003e\n  \u003cli\u003e0.002 inch corner radius for fine-detail chamfering with minimal edge stress\u003c\/li\u003e\n  \u003cli\u003eIC908 manufacturer grade suited for high-performance cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling solution for CNC turning centers and lathes that accept 4.00 mm shank boring bars with right-hand cutting orientation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or removing the boring bar. Verify shank diameter compatibility with the toolholder bore and confirm secure clamping torque per the toolholder manufacturer specification before initiating any cutting cycle. Avoid exceeding the maximum bore depth of 0.6299 inches to prevent tool deflection or 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: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1811 inches (30.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar End Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6405285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737515655474,"sku":"6405285","price":77.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93a446298ff9461275d7092833afa095.jpg?v=1788789593","url":"https:\/\/voomisupply.com\/products\/iscar-6405285-chamfering-boring-bar-submicron-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
