Built from submicron solid carbide in the IC908 grade, this right-hand cut tool delivers consistent performance in demanding interior chamfering applications. The bar carries a TiAlN coating for heat and oxidation resistance at elevated cutting speeds. With a minimum bore diameter of 0.0394 inches and a 60-degree bar end angle, it is well suited for small-bore chamfering where tool clearance and edge geometry are critical to finish quality.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use on CNC lathes and boring machines in precision machining environments, including toolrooms, production shops, and aerospace or medical component manufacturing. The right-hand cutting direction and compact shank make it applicable in Swiss-style and small-bore turning setups where access is restricted and dimensional accuracy requirements are tight. Licensed machinists and CNC operators are the primary end users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction in IC908 grade for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e60-degree bar end angle optimized for chamfering operations inside bores\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.0394 inches enables work in very small bore diameters\u003c\/li\u003e\n\u003cli\u003e0.008 inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe and boring machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar for small-bore chamfering applications on CNC lathes and boring machines accepting a 5 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per applicable safety procedures. Secure the shank in the tool holder to the manufacturer-specified clamping torque for the holder in use  -  do not rely on estimated values. Verify bore clearance and tool overhang before engaging the cut to avoid deflection or chatter. Inspect the cutting edge for coating integrity before each use.\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\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: 0.008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBar End Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Submicron Solid Carbide\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6404225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51744443859250,"sku":"6404225","price":96.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3b3b58a6342f595344183624ccaab33.jpg?v=1788856570","url":"https:\/\/voomisupply.com\/products\/iscar-6404225-chamfering-boring-bar-0-0394-in-min-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
