Built from submicron-grade carbide with a TiAlN and TiN finish coating, it delivers consistent edge integrity and wear resistance in demanding cutting applications. The bar features a right-hand cutting direction, a 20-degree bar end angle, and a 0.004 inch corner radius, making it suited for fine finishing passes in tight bore geometries. With an overall length of 0.9449 inches and a minimum bore diameter of 0.1378 inches, this tool is designed for machinists working in precision machining environments where bore access is restricted and dimensional accuracy is critical.\u003c\/p\u003e\n\u003cp\u003eThis chamfering boring bar is intended for use in CNC turning centers, boring mills, and similar machine tool setups requiring internal chamfer geometry on small bores. It handles a maximum bore depth of 0.3937 inches and is ground to ISCAR manufacturer grade IC908, a submicron carbide grade known for its toughness and performance in steel and stainless steel applications. It is typically installed by machinists, tool-and-die professionals, and precision parts manufacturers running production or prototype work on small-diameter components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for high edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN and TiN dual finish coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with 20-degree bar end angle for precise internal chamfering\u003c\/li\u003e\n  \u003cli\u003e0.004 inch corner radius for controlled edge geometry on finish passes\u003c\/li\u003e\n  \u003cli\u003eCompact 0.9449 inch overall length suited for restricted-access bore applications\u003c\/li\u003e\n  \u003cli\u003eISCAR IC908 manufacturer grade for consistent performance in demanding cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide boring bar for small-bore internal chamfering applications on CNC turning and boring equipment accepting a 4.00 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for boring bar setup and runout tolerance. Ensure the machine spindle and tool holder are fully de-energized and locked out before mounting or removing the bar. Verify shank seating and projection length against the specified bore depth before initiating a cut. Do not exceed the maximum bore depth rating of 0.3937 inches for this tool.\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: 0.1378 inches (3.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.9449 inches (24.00 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\u003eCorner Radius\u003c\/strong\u003e: 0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar End Angle\u003c\/strong\u003e: 20 degrees\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: 0.011 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: 6405286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735661838642,"sku":"6405286","price":77.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5fc919a77caffcd9e4793562a70fd50.jpg?v=1788773514","url":"https:\/\/voomisupply.com\/products\/iscar-6405286-chamfering-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
