Built to the HBBC toolholder style, it accepts CD-style inserts secured by a screw clamping method, providing repeatable insert positioning and rigid cutting performance. The bar features a 3\/8-inch shank diameter, a 2.5-inch overall length, and a minimum bore diameter of 0.208 inches, making it well suited for small-bore finish and semi-finish applications. Coolant-through capability supports chip evacuation and tool life in demanding cuts. Licensed machinists and CNC lathe operators are the primary users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for small-diameter internal turning work where access is limited and precise bore geometry is required. The right-hand cut orientation makes it compatible with standard forward-turning setups on conventional and CNC lathes. A maximum bore depth of 1.0 inch keeps the application focused on shorter, controlled bores where rigidity and accuracy are priorities. It is appropriate for use in job shop, production machining, and toolroom environments working with a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHBBC toolholder style with screw insert clamping for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eAccepts CD-style inserts for broad grade and geometry availability\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip control and extends insert life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard forward-turning lathe setups\u003c\/li\u003e\n  \u003cli\u003eSteel construction balances rigidity and weight for small-bore applications\u003c\/li\u003e\n  \u003cli\u003e0.208-inch minimum bore diameter enables access to tight internal diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept CD-style inserts. Verify insert grade, geometry, and nose radius selection against workpiece material and cut parameters before installation. Confirm shank-bore fit and holder clearance on the target machine before use.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist familiar with lathe tooling and cutting insert systems. Secure the shank fully within the tool post or turret bore to the recommended grip length before beginning any cut. Ensure the machine is fully stopped and locked out before changing inserts or adjusting the boring bar position. Follow the insert manufacturer torque guidance for the clamping screw to avoid insert movement or damage during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.208 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CD-style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.75 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H59868174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747522445618,"sku":"H59868174","price":254.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53f42a6472e8e6abdcb67c5c8de9a0ec.jpg?v=1788881852","url":"https:\/\/voomisupply.com\/products\/hertel-h59868174-indexable-boring-bar-3-8-inch-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
