Built to HBBG toolholder style, it accepts WPGT inserts secured by a screw-clamp holding method, providing repeatable insert location and rigid cutting performance. The bar features a left-hand cut orientation, a minimum bore diameter of 0.347 inches, and a maximum bore depth of 3.125 inches. Overall length is 6 inches with a 5\/16-inch shank diameter. Coolant-through capability supports chip evacuation and tool life in deep-bore applications. Typically installed by CNC machinists and toolroom technicians in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for tight-bore finish and semi-finish turning in both ferrous and non-ferrous materials where a left-hand cut configuration is required. The 5\/16-inch solid carbide shank provides high rigidity relative to its diameter, reducing chatter in small-diameter, deep-bore scenarios. The WPGT insert platform is a standard geometry compatible with a range of insert grades for varied work materials. This tool is appropriate for use in precision machining applications where bore diameter tolerance and surface finish are critical requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut orientation for specific boring configurations\u003c\/li\u003e\n\u003cli\u003eSolid carbide shank construction for maximum rigidity in small-bore applications\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and extended tool life in deep bores\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method ensures secure, repeatable WPGT insert seating\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.347 inches with maximum bore depth of 3.125 inches\u003c\/li\u003e\n\u003cli\u003eHBBG toolholder style for consistent system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with WPGT series inserts.

Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before mounting or removing the boring bar. Set shank projection to the minimum required overhang to maximize rigidity and reduce deflection. Confirm insert seating and screw torque per the insert manufacturer's tooling system guidelines before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.347 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left 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: WPGT\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: 6.25 inches (L) x 0.5 inches (W) x 0.5 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08614836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729223713074,"sku":"H08614836","price":613.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efb692cb24241f1a91db33e02ff8a4e4.jpg?v=1788702035","url":"https:\/\/voomisupply.com\/products\/hertel-h08614836-indexable-boring-bar-0-347in-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
