Built from steel with a 1-inch shank diameter and 12-inch overall length, it accepts WNMG 332 trigon-style inserts held by a pin-and-clamp system. The minimum bore diameter is 1.2 inches, making it suited for moderate to deep internal bores. With a negative rake angle of -14 degrees and a lead angle of -5 degrees, this bar delivers controlled chip formation and stable cutting performance during right-hand turning passes.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision turning applications where internal diameter finishing or semi-finishing is required. It is appropriate for both production shop and job shop environments running steel, cast iron, and similar materials at standard cutting parameters. The MWLN toolholder style is a widely recognized standard in indexable turning, and this bar fits tooling setups where a 1-inch shank is the specified holding diameter. The insert inscribed circle of 3\/8 inch and a center-to-cutting-edge measurement of 0.640 inches define the cutting geometry for this bar.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMWLN toolholder style with pin-and-clamp insert retention for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eAccepts WNMG 332 trigon inserts with a 3\/8-inch inscribed circle and 3\/16-inch insert thickness\u003c\/li\u003e\n\u003cli\u003e1.2-inch minimum bore diameter and 12-inch overall length for reach into deeper bores\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry (-14 degrees rake, -5 degrees lead angle) for stable cutting on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; steel shank construction for rigidity\u003c\/li\u003e\n\u003cli\u003eNo coolant-through — external coolant application required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with WNMG 332 trigon-style inserts (insert size code 33, compatible insert size 187R).

Before changing inserts or adjusting the bar, ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state. Secure the 1-inch shank in a properly sized boring bar holder or turret station and verify tool overhang does not exceed recommended limits for the workpiece setup. Follow the machine tool manufacturer and insert supplier guidelines for speed, feed, and depth-of-cut parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MWLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -14 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WNMG 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Trigon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 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\u003eCompatible Insert Size Code\u003c\/strong\u003e: 33\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 187R\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\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.640 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\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\u003eHand of Holder\u003c\/strong\u003e: Right Hand\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: 75051590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563103846706,"sku":"75051590","price":489.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00a377b94fcf39abbc7a24724771e691.jpg?v=1786490705","url":"https:\/\/voomisupply.com\/products\/seco-75051590-mwln-indexable-boring-bar-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
