Built from steel, it accepts CNMG 432 inserts held in place by a pin and clamp method. The bar features a 1.53-inch minimum bore diameter, a 1-1\/4-inch shank diameter, and a 14-inch overall length. A 95-degree lead angle combined with a negative 5-degree rake angle positions the cutting edge for stable, controlled material removal. Through-coolant capability directs fluid directly to the cutting zone, helping manage heat and chip evacuation during deep-bore operations. This tool is intended for use by machinists and tool-and-die professionals on CNC lathes and boring mills.\u003c\/p\u003e\u003cp\u003eThis boring bar suits left-hand internal turning setups where tool clearance, reach, or machine orientation requires a left-hand cutting direction. The 14-inch overall length provides reach for deeper bores, while the 1-1\/4-inch shank fits standard toolholding systems. Through-coolant support makes this bar well suited for continuous cuts in steel, cast iron, and similar materials where heat buildup and chip control are primary concerns. It is a single-use-direction, non-multi-use tool intended for dedicated turning operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with A-MCLN toolholder style\u003c\/li\u003e\n\u003cli\u003eAccepts CNMG 432 diamond-shaped inserts with 1\/2-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003ePin and clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eThrough-coolant channel for direct coolant delivery to the cutting edge\u003c\/li\u003e\n\u003cli\u003e95-degree lead angle and negative 5-degree rake for stable turning geometry\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity in demanding boring applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNMG 432 inserts (compatible insert size code 43, 3\/16-inch insert thickness, 1\/2-inch inscribed circle).

Power down and lock out the machine before mounting or removing the boring bar. Ensure the shank is clamped securely and squarely in the toolholder to the full recommended engagement depth before operation. Connect the through-coolant supply line per machine specifications before running coolant-assisted cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.53 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 95 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CNMG 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.765 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Pin and Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\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\u003eToolholder Style\u003c\/strong\u003e: A-MCLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00041051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559216677170,"sku":"00041051","price":470.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17bf4bd74615a8a202a0baf912680a45.jpg?v=1786429888","url":"https:\/\/voomisupply.com\/products\/seco-00041051-indexable-boring-bar-1-53in-left-hand-a-mcln","provider":"Voomi Supply","version":"1.0","type":"link"}
