With a minimum bore diameter of 0.0394 inches and a maximum bore depth of 0.1772 inches, this bar is built for tight, precise work in miniature and small-diameter bores. The right-hand cutting direction suits standard spindle configurations. A TiCN and TiN finish coating over the IC228 carbide grade provides wear resistance and extended tool life in a range of ferrous and non-ferrous workpiece materials. A corner radius of 0.002 inches supports sharp, controlled chamfer geometry.\u003c\/p\u003e\u003cp\u003eThis chamfering boring bar is suited for precision machining applications where small bore entry and shallow depth requirements demand a compact, rigid tool. Typical applications include chamfering pre-drilled holes, deburring bore entries, and producing internal chamfers on small components in aerospace, medical device, and precision mechanical industries. It is installed and operated by machinists and CNC tooling technicians working with live tooling or turret-based setups on lathes and multi-axis machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eTiCN and TiN dual finish coating extends cutting edge life and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003eIC228 manufacturer grade carbide suited for a range of cutting conditions\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.0394 inches enables access to very small bore entries\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.002 inches for precise chamfer geometry control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide chamfering boring bar for use in CNC lathes and machining centers with tooling systems accommodating a 4.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Secure the shank firmly in the appropriate tool holder and verify runout before commencing cuts. Power down the machine and lock out energy sources before changing or adjusting tooling. Follow the machine tool manufacturer guidelines for speeds, feeds, and depth of cut when using small-diameter carbide boring bars to avoid tool breakage.\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: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.1772 inches (4.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7874 inches (20.00 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: 0.002 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: IC228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 6403794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51749207769394,"sku":"6403794","price":86.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/687c1a6762b3859fd7466b05aae00c36.jpg?v=1788903152","url":"https:\/\/voomisupply.com\/products\/iscar-6403794-chamfering-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
