Built to the HBBC toolholder style, it accepts CD-series inserts secured by a screw clamping method, providing repeatable insert indexing and rigid tool engagement. The minimum bore diameter is 0.222 inches, the shank diameter is 3\/16 inches, and the overall length is 4 inches. Coolant-through capability is included, supporting chip evacuation and tool life in demanding bore finishing applications. This bar is intended for right-hand cutting. Machinists and toolroom technicians working in precision bore sizing will find this geometry well matched to tight-tolerance internal features.\u003c\/p\u003e\u003cp\u003eThis boring bar suits small-diameter internal boring applications in production and job-shop environments. It is appropriate for use in CNC turning centers and live-tool lathes where a 3\/16-inch shank fits the toolholder block. The maximum bore depth reaches 1.875 inches (1-7\/8 inches), making it capable of moderate-depth finish boring passes. It is a single-purpose, right-hand toolholder and is not configured for multi-use or left-hand operation. Typical applications include bore sizing, light roughing, and finish passes in ferrous and non-ferrous workpiece materials.\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\u003eMinimum bore diameter of 0.222 inches suits tight internal feature requirements\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.875 inches (1-7\/8 inches) handles moderate-depth passes\u003c\/li\u003e\n\u003cli\u003eScrew clamp insert retention ensures secure, repeatable CD-series insert indexing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and extended insert life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation; 3\/16-inch shank diameter for standard small-bore toolblocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CD-series indexable inserts. Compatible with toolholder blocks accepting a 3\/16-inch shank diameter. Specific compatible insert grades and geometries should be confirmed against the CD insert series specifications for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the toolholder block to the recommended grip length before operation; insufficient shank engagement increases deflection risk in small-diameter bores. Ensure the machine spindle is fully stopped and the turret is de-energized before inserting or indexing the bar. Follow the insert manufacturer torque guidelines for the clamping screw to prevent insert movement or screw damage during cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.222 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.875 inches (1-7\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CD series\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches L x 0.25 inches W x 0.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H59868398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731241795890,"sku":"H59868398","price":483.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4629039216a126eab547d965abfae7f9.jpg?v=1788728739","url":"https:\/\/voomisupply.com\/products\/hertel-h59868398-indexable-boring-bar-0-222-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
