Built from steel with a 1-1\/4 inch shank diameter and 14 inch overall length, it accepts CNMG 432 inserts secured by a pin and clamp holding method. The minimum bore diameter is 1.53 inches, making it suited for mid-range bore work. Through-coolant capability is built in via a 0.375 inch coolant hole, supporting chip evacuation and tool life in continuous cuts. The negative rake geometry and -5 degree lead angle are optimized for consistent, stable cuts in ferrous and hard materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for professional machining environments where precise internal diameter work is required. It is appropriate for job shop, production, and maintenance machining applications involving steel, cast iron, and similar materials. The right-hand cutting direction and MCLN toolholder style are standard configurations for conventional CNC lathe setups. Compatible hardware includes clamp screw XNS-47, clamp CL-20, and lock pin NL-44. The manufacturer also references this tool under the number A20-MCLNR-4.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts CNMG 432 inserts with pin and clamp holding method for positive insert location\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 0.375 inch coolant hole diameter supports chip control and extended insert life\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch steel shank with 14 inch overall length provides rigidity in deep bore applications\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -14 degrees and -5 degree lead angle optimized for stable cutting in hard materials\u003c\/li\u003e\n\u003cli\u003eCenter to cutting edge of 0.765 inches for consistent bore diameter reference during setup\u003c\/li\u003e\n\u003cli\u003eClamp hardware included: XNS-47 screw, CL-20 clamp, NL-44 lock pin\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNMG 432 diamond-shaped inserts with a 1\/2 inch inscribed circle and 3\/16 inch thickness.

Power down and lock out the machine spindle before changing inserts or adjusting the boring bar. Ensure the shank is clamped securely in the turret or toolpost to the full recommended engagement length to minimize overhang deflection. Follow the machine tool builder guidelines and applicable shop safety procedures when connecting through-coolant lines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.53 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\u003eOverall Length\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\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\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\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.375 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\u003eClamp Screw\u003c\/strong\u003e: XNS-47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp\u003c\/strong\u003e: CL-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Pin\u003c\/strong\u003e: NL-44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 00041050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559404077362,"sku":"00041050","price":470.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dc8c84355f73050ce8822d43f36f989.jpg?v=1786431403","url":"https:\/\/voomisupply.com\/products\/seco-00041050-indexable-boring-bar-right-hand-mcln","provider":"Voomi Supply","version":"1.0","type":"link"}
