Built to the A-PWLN toolholder style within ISCAR's Isoturn series, it accepts WNM 06T3 trigon inserts held by a lever clamping mechanism. The bar features a 20mm shank diameter and a 180mm overall length, providing the rigidity needed to reach a maximum bore depth of 36mm. A through-coolant channel delivers cutting fluid directly to the insert tip, improving chip evacuation and extending tool life in demanding bore finishing and roughing applications. Machining professionals and CNC setup technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for left-hand internal turning where the spindle rotation and tool orientation require a left-cutting-direction setup. It opens bores to a minimum diameter of 25mm, making it appropriate for mid-range bore diameters common in production turning of steel and similar materials. The negative rake geometry at -14 degrees and trigon insert shape support aggressive material removal while maintaining a secure insert seating. Applications span job shops, production machining facilities, and tool rooms requiring consistent bore geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA-PWLN toolholder style from the Isoturn series for consistent insert positioning\u003c\/li\u003e\n  \u003cli\u003eAccepts WNM 06T3 trigon inserts with lever clamping for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant channel directs fluid to the cutting zone for chip control and heat management\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction with negative rake angle of -14 degrees\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides rigidity across the 180mm overall length\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with digital tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with WNM 06T3 series trigon inserts.

Power down the machine and lock out the spindle before mounting or removing the boring bar. Secure the shank fully within the toolholder to the machine manufacturer's specified clamping depth to prevent deflection during cutting. Confirm coolant supply line connection to the through-coolant port before initiating a cutting cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 25mm (0.9843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 36mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 180mm (7.0866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 20mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 13mm (0.5118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-PWLN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -14 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WNM 06T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Trigon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3601191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748273193266,"sku":"3601191","price":527.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f37f4a92e144f576d93c6bf6a74ec2d8.jpg?v=1788891551","url":"https:\/\/voomisupply.com\/products\/iscar-3601191-indexable-boring-bar-25mm-left-hand-a-pwln","provider":"Voomi Supply","version":"1.0","type":"link"}
