With a minimum bore diameter of 0.1969 inches (5.00 mm) and a maximum bore depth of 0.5512 inches (14.00 mm), this bar handles tight-tolerance small-bore work where rigidity and precision are critical. The 5.00 mm shank diameter and 1.1811 inch overall length make it well-suited for confined tooling envelopes. A TiCN and TiN finish coating in ISCAR grade IC908 provides wear resistance and thermal stability across a range of workpiece materials. Machining professionals and toolroom technicians working with small-diameter bores will find this bar suited for production and job-shop environments alike.\u003c\/p\u003e\u003cp\u003eThis chamfering boring bar is intended for right-hand cutting operations in small-bore applications on lathes and turning centers. It is applicable in production machining of steel, stainless steel, and similar materials where a fine chamfer or internal profile is required at bore diameters starting at 0.1969 inches. The compact geometry and solid carbide construction make it appropriate for high-rpm finishing passes where deflection must be minimized. It is typically used by machinists and CNC operators working with precision components in aerospace, medical, and general manufacturing contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity in small-bore applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.1969 inches (5.00 mm) enables work in very tight bores\u003c\/li\u003e\n\u003cli\u003eTiCN and TiN dual finish coating for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003eISCAR grade IC908 for consistent performance across ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e0.0059 inch corner radius for controlled chamfer geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and turning center setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling solution for CNC lathes and turning centers requiring right-hand chamfering boring bars with a 5.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the toolholder is properly clamped before inserting or adjusting the bar. Confirm shank seating depth and runout with a dial indicator before initiating a cut. Follow the machine tool manufacturer guidelines for toolholder torque and overhang limits to avoid chatter or premature tool wear.\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: 0.1969 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.5512 inches (14.00 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: 5.00 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: TiCN and TiN\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: 0.01 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: 6403783\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733617475890,"sku":"6403783","price":72.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca14994864f3834e8945b0aa597dd84c.jpg?v=1788756972","url":"https:\/\/voomisupply.com\/products\/iscar-6403783-chamfering-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
