Built to A-SWLP toolholder style specifications, this steel bar accepts WP-style inserts secured by a screw-clamping method. It features a 0.6 inch minimum bore diameter and an 8 inch overall length, making it well-suited for deeper bore applications where rigidity and coolant delivery are critical. Through-coolant capability with a 1\/16-27 NPT coolant hole thread size ensures chip evacuation and thermal control at the cutting zone. Licensed machinists and CNC operators working with tight-tolerance bore work will find this bar appropriate for production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in metalworking operations requiring left-hand cutting geometry on internal diameters starting at 0.6 inches. The 0.5 inch shank diameter fits standard lathe toolposts and boring bar holders. A neutral rake angle and a -5 degree lead angle provide stable cutting action on a range of workpiece materials. The through-coolant design makes it particularly effective in interrupted cuts or when working with steels and alloys that generate significant heat at the cutting edge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand A-SWLP toolholder style with screw insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eAccepts WP-style indexable inserts with a 0.25 inch inscribed circle and 3\/32 inch insert thickness\u003c\/li\u003e\n\u003cli\u003eThrough-coolant ready with 1\/16-27 NPT thread for direct coolant-to-edge delivery\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle and -5 degree lead angle for controlled, stable boring performance\u003c\/li\u003e\n\u003cli\u003eBack-of-bar to cutting edge and center-to-cutting-edge dimension both at 0.312 inches for consistent offset setup\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in production boring applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with WP-style indexable inserts with a 0.25 inch inscribed circle.

Power down and lock out the machine before mounting or removing the boring bar. Ensure the shank is fully supported in the holder with adequate clamping length to minimize overhang-induced vibration. Verify coolant line connection to the 1\/16-27 NPT port before resuming operation, and confirm insert seating and screw torque per the insert manufacturer's guidelines before taking a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-SWLP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WP style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/16-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 7000076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753408856370,"sku":"7000076","price":258.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/116159e849db06df0273f4e814fa91ca.jpg?v=1788936464","url":"https:\/\/voomisupply.com\/products\/hertel-7000076-indexable-boring-bar-left-hand-a-swlp","provider":"Voomi Supply","version":"1.0","type":"link"}
