Built from steel, this toolholder uses a screw-type insert holding method compatible with WPMT-style inserts. It features a 5\/8-inch shank diameter and an overall length of 7 inches, making it well-suited for shops that need reliable, repeatable bore geometry on CNC lathes and manual turning equipment. Coolant-through capability allows for improved chip evacuation and extended insert life during continuous cutting cycles. This bar is a single-use toolholder style, not a multi-use configuration.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for machining environments where left-hand cutting geometry is required, typically in situations involving back-boring or specific lathe setup orientations. The HBBS toolholder style accommodates a minimum bore diameter of 0.675 inches and a maximum bore depth of 2.5 inches. It is appropriate for job shops, production machining facilities, and maintenance operations where close-tolerance internal diameters are required. Professional machinists and CNC operators handling steel and similar materials will find this bar fits standard toolpost and turret setups with a 5\/8-inch shank pocket.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting orientation for back-boring and specialized lathe setups\u003c\/li\u003e\n\u003cli\u003eCoolant-through design improves chip flushing and insert longevity\u003c\/li\u003e\n\u003cli\u003eScrew-type insert retention provides secure clamping with WPMT inserts\u003c\/li\u003e\n\u003cli\u003e0.675-inch minimum bore diameter with up to 2.5-inch maximum bore depth\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability in metalworking applications\u003c\/li\u003e\n\u003cli\u003eHBBS toolholder style for consistent, repeatable setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with WPMT-style indexable inserts.

Ensure the machine spindle is fully stopped and all motion has ceased before changing inserts or adjusting the bar in the turret or toolpost. Verify proper shank clamping torque per the machine tool manufacturer guidelines and confirm insert seating before taking any cuts. Do not exceed the maximum bore depth rating of 2.5 inches to avoid deflection or insert failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.675 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: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 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\u003eToolholder Style\u003c\/strong\u003e: HBBS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WPMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\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: 7.25 inches (L) x 0.75 inches (W) x 0.75 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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: H08614935\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729014849842,"sku":"H08614935","price":265.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b9d776b9065fb7263d5d23578cdb947.jpg?v=1788698852","url":"https:\/\/voomisupply.com\/products\/hertel-h08614935-indexable-boring-bar-left-hand-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
