Built on the HBBG toolholder style, this left-hand-cut bar handles a minimum bore diameter of 0.285 inches and a maximum bore depth of 2.5 inches. The shank measures 0.25 inches in diameter with an overall length of 6 inches. Insert retention is handled by a screw-clamp holding method, providing rigid, repeatable seating. Coolant-through capability supports chip evacuation and tool life in deep-bore applications. Licensed machinists and CNC operators install and use this tooling.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-bore internal machining where left-hand cutting geometry is required. Typical applications include finishing and semi-finishing of tight-tolerance bores in production turning environments. The coolant-through design makes it particularly effective in materials that generate heat or stringy chips. With a 0.285-inch minimum bore diameter, it is well matched to close-clearance bore work on ferrous and non-ferrous workpieces. The solid carbide body provides rigidity and vibration resistance at extended reach relative to shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut geometry for right-to-left boring direction\u003c\/li\u003e\n\u003cli\u003eSolid carbide body for rigidity and vibration damping in small-bore applications\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and thermal management\u003c\/li\u003e\n\u003cli\u003eCompatible with WPGT insert series\u003c\/li\u003e\n\u003cli\u003e0.285-inch minimum bore diameter with 2.5-inch maximum bore depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept WPGT series indexable inserts.

Always power down and lock out the machine spindle before changing inserts or setting tool offsets. Ensure the shank is clamped securely in the tool turret or boring bar holder to the depth recommended by the machine tool manufacturer. Handle carbide tooling carefully to avoid chipping the shank or cutting edge during setup.\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: 0.285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\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: H08614810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729180164402,"sku":"H08614810","price":429.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7417fbd956fc1e23864329dbaa033c9.jpg?v=1788701495","url":"https:\/\/voomisupply.com\/products\/hertel-h08614810-indexable-boring-bar-0-285-in-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
