With a minimum bore diameter of 0.1575 inches and a maximum bore depth of 1.063 inches, this bar handles tight, deep-bore chamfering tasks where rigidity and precision are critical. The right-hand cutting direction suits standard CNC lathe and boring setups. A TiCN and TiN finish coating improves wear resistance and surface finish performance. Manufacturer grade IC228 carbide substrate is suited for a range of workpiece materials encountered in precision machining environments. Qualified machinists and CNC operators install and qualify this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis chamfering boring bar is intended for use in CNC lathes and machining centers performing internal chamfering or countersinking operations in small-diameter bores. The 0.1575 inch minimum bore diameter makes it well suited for micro-bore and small-diameter precision work in aerospace, medical, and general precision machining applications. The 1.6548 inch overall length and 0.0039 inch corner radius support accurate, repeatable chamfer geometry in production and job-shop environments alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eTiCN and TiN finish coating for improved wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade IC228 substrate designed for precision cutting performance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard lathe and boring configurations\u003c\/li\u003e\n  \u003cli\u003e0.0039 inch corner radius for controlled chamfer geometry\u003c\/li\u003e\n  \u003cli\u003eCompact 1.6548 inch overall length suited for tight machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement boring bar for CNC lathes and machining centers capable of accepting solid carbide small-bore tooling with 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 or CNC setup technician. Power down and lock out the machine spindle before changing or adjusting tooling. Ensure the tool is properly seated and clamped in the tool holder to the holding specification of the machine tool manufacturer before resuming operations. Verify bore diameter and depth clearances before initiating a cut.\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.063 inches (27.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6548 inches (42.00 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: 0.0039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: IC228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 6403671\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51740208431410,"sku":"6403671","price":106.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b609e8b661cff1ff22c15bd5e18b9c3.jpg?v=1788823524","url":"https:\/\/voomisupply.com\/products\/iscar-6403671-chamfering-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
