Built from steel, it features a 1.0 inch shank diameter and a 12 inch overall length, making it suited for reaching into deeper bores with a minimum bore diameter of 1.28 inches. The toolholder uses a pin and clamp insert holding method and accepts WNMG 432 trigon inserts with a 1\/2 inch inscribed circle. The negative rake geometry at -14 degrees and a -5 degree lead angle support stable, controlled cutting in left-hand cutting direction applications.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for turning and internal bore finishing operations in metal cutting environments, including production machining shops and job shops running ferrous and non-ferrous materials. The MWLN toolholder style is a standard configuration commonly found in CNC turning setups. The 0.64 inch center-to-cutting-edge measurement and 3\/16 inch insert thickness suit moderate to heavy boring passes. This tool does not include coolant-through capability, so external coolant delivery should be planned accordingly in high-heat applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with MWLN toolholder style for internal turning\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 1.28 inches with a 12 inch overall length for extended reach\u003c\/li\u003e\n\u003cli\u003eAccepts WNMG 432 trigon inserts with 1\/2 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003ePin and clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -14 degrees and -5 degree lead angle for controlled cutting geometry\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity in standard turning center setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with WNMG 432 trigon inserts, compatible insert size code 43\/44.

Secure the shank firmly in the tool turret or boring bar holder to the equipment manufacturer's specified clamping procedure before running the spindle. Verify insert seating and clamp torque before each use per the insert manufacturer's guidelines. Do not exceed the machine's rated spindle speed or depth-of-cut limits for the insert grade selected.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.0 inch\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: MWLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WNMG 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 43\/44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch\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\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\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\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: 00043222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557634736434,"sku":"00043222","price":451.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e1c05bc6b2a79803e7cd19fcaf8a7a0.jpg?v=1786391656","url":"https:\/\/voomisupply.com\/products\/seco-00043222-left-hand-mwln-indexable-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
