Machined from submicron-grade solid carbide with a TiAlN and TiN finish coating, this bar delivers the wear resistance and edge stability required for tight-tolerance work. It features a right-hand cutting direction, a 20-degree bar end angle, and a 0.001-inch corner radius. With a minimum bore diameter of 0.1102 inches and a maximum bore depth of 0.748 inches, it is suited for small, deep-bore chamfering where rigidity and carbide quality directly affect finish results. The overall length is 1.3386 inches.\u003c\/p\u003e\u003cp\u003eThis chamfering boring bar is intended for use in CNC turning centers and manual lathes performing internal chamfering on small-diameter bores. It is appropriate for applications in precision machined components where bore entry chamfers must be held to consistent angles and surface finish standards. The IC908 manufacturer grade and submicron carbide substrate make it a fit for harder workpiece materials and interrupted cuts where standard carbide may chip or wear prematurely. The 4.00 mm shank diameter is suited to small-bore tooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide substrate in ISCAR IC908 grade for enhanced toughness 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\u003eRight-hand cutting direction with a 20-degree bar end angle for precise chamfer geometry\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.1102 inches enables use in very small internal features\u003c\/li\u003e\n\u003cli\u003e0.001-inch corner radius for sharp, accurate chamfer transitions\u003c\/li\u003e\n\u003cli\u003eCompact 1.3386-inch overall length reduces overhang and improves rigidity in confined setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling solution for small-bore chamfering applications using 4.00 mm shank boring bar holders compatible with ISCAR tooling systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all power is off before changing or setting tooling. Verify shank seating and tool stick-out against the specified maximum bore depth before running the first pass. Do not exceed the recommended bore depth or use the bar in bore diameters below the stated minimum, as deflection and tool breakage risk increase significantly outside these limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.748 inches (19.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.3386 inches (34.00 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: 0.001 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 (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\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: 6496120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51740010578226,"sku":"6496120","price":96.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/644cac936bd531fd6cc1685790d0749b.jpg?v=1788821441","url":"https:\/\/voomisupply.com\/products\/iscar-6496120-chamfering-boring-bar-submicron-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
