Built from steel with a pin-and-clamp insert holding method, it accepts CNMG 322 inserts and delivers a negative rake geometry suited to stable, controlled material removal. The bar features a 1.0000-inch minimum bore diameter and a 3\/4-inch shank diameter, making it a practical choice for machinists and toolroom professionals running CNC lathes or manual boring setups where repeatable insert indexing is required.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for turning and internal boring applications in production and job-shop environments. The MCLN toolholder style positions the CNMG insert at a -5-degree lead angle and a -14-degree rake angle, geometry suited to medium and finishing passes in ferrous and non-ferrous materials. The 10-inch overall length provides clearance for deeper bores while the 3\/4-inch shank fits standard boring bar holders and turret pockets sized for that shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMCLN toolholder style with pin-and-clamp insert retention for rigid, repeatable seating\u003c\/li\u003e\n\u003cli\u003eAccepts CNMG 322 diamond-shaped inserts with a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with negative rake geometry (-14-degree rake angle)\u003c\/li\u003e\n\u003cli\u003e-5-degree lead angle reduces radial cutting forces during internal turning\u003c\/li\u003e\n\u003cli\u003eSteel construction provides rigidity and resistance to deflection in boring applications\u003c\/li\u003e\n\u003cli\u003e10-inch overall length accommodates deeper bore depths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CNMG 322 inserts with a compatible insert size code of 32 and a 1\/8-inch insert thickness.

Secure the 3\/4-inch shank in the turret or boring bar holder to the tool manufacturer and machine builder specifications, ensuring adequate shank engagement to minimize overhang-related deflection. Inspect the insert seat and clamping pin before each insert index. Follow the machine tool builder guidelines and applicable shop safety procedures when setting tool offsets and confirming bore dimensions.\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\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 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\u003eInsert Compatibility\u003c\/strong\u003e: CNMG 322\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.5000 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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\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: 00043201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560255848754,"sku":"00043201","price":414.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f214173865a6e0142a8cb43b6a14bc34.jpg?v=1786449722","url":"https:\/\/voomisupply.com\/products\/seco-00043201-indexable-boring-bar-mcln-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
