With a minimum bore diameter of 0.1969 inches (5.00 mm) and a maximum bore depth of 0.748 inches (19.00 mm), this bar is suited for small-bore finishing and semi-finishing work. The right-hand cutting direction and 0.1500-inch corner radius make it compatible with standard right-hand tooling setups. A TiN finish coating helps extend tool life in ferrous and non-ferrous applications. Machining professionals and toolroom technicians select this bar when tight bore tolerances and consistent chip evacuation are priorities.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in small-bore internal turning applications on machining centers, CNC lathes, and manual lathes capable of holding a 5.00 mm shank. The 35.00 mm overall length suits compact toolholders and Swiss-style or gang-tool setups where minimal overhang is required. The solid carbide construction provides rigidity and vibration resistance in tight-bore configurations where steel shanks would deflect. It is appropriate for both production environments and job-shop applications requiring repeatable bore geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter: 0.1969 inches (5.00 mm) for small-bore internal operations\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth: 0.748 inches (19.00 mm)\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and reduced deflection in small-bore applications\u003c\/li\u003e\n\u003cli\u003eTiN finish coating for improved wear resistance and tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and turning center setups\u003c\/li\u003e\n\u003cli\u003eISCAR manufacturer grade IC228 insert or substrate designation\u003c\/li\u003e\n\u003cli\u003eCorner radius: 0.1500 inches for consistent surface finish control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring bar for toolholding systems accepting a 5.00 mm round shank with a 35.00 mm overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of boring bars should be performed by a qualified machinist with the machine fully powered down and the spindle locked before tool changes. The bar shank must be clamped securely in a compatible boring head or toolholder to the manufacturer-specified clamping length to prevent chatter and tool pull-out during cutting. Verify shank runout with a dial indicator before commencing cuts. Always confirm bore clearance and depth stop settings before initiating the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 0.748 inches (19.00 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\u003eOverall Length\u003c\/strong\u003e: 35.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1500 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: 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: 6402279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755246223666,"sku":"6402279","price":79.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fd172fb702abe5b6238e53d954dec8f.jpg?v=1788952603","url":"https:\/\/voomisupply.com\/products\/iscar-6402279-solid-carbide-boring-bar-0-1969-in-min-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
