Built from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN in the TT8125B grade, this insert is engineered for steel turning applications where wear resistance and thermal stability are critical. The diamond-shaped insert features a negative rake geometry, a 0.031 inch corner radius, an 80-degree included angle, and four usable cutting edges, offering high efficiency per insert. The PC chip breaker geometry supports reliable chip control across a wide range of depths and feed rates.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning of steel workpieces (ISO material group P) in both roughing and semi-finishing operations. The ANSI code CNMG432PCTT8125B and ISO code CNMG120408PC TT8125B define the exact geometry and grade combination. A maximum depth of cut of 0.196 inch makes it appropriate for moderate material removal on production turning setups. The neutral hand orientation and clamp-style holding method are compatible with standard CNMG toolholders used in shop-floor and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with CVD multilayer TiCN\/Al2O3\/TiN coating (TT8125B grade) for extended tool life on steel\u003c\/li\u003e\n\u003cli\u003eDiamond insert shape (80-degree included angle) provides a strong cutting edge with good approach-angle flexibility\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert reduce per-edge tooling cost in high-volume turning\u003c\/li\u003e\n\u003cli\u003ePC chip breaker geometry promotes consistent chip evacuation across varying feed and depth conditions\u003c\/li\u003e\n\u003cli\u003eNegative rake, neutral hand geometry fits a wide range of standard CNMG clamp-style toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.196 inch supports semi-roughing and finishing passes on steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNMG clamp-style toolholders with a 0.5 inch inscribed circle seating geometry (insert size code 432).

Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing or rotating inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new cutting edge. Follow all applicable shop safety procedures for handling sharp carbide inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT8125B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.196 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG432PCTT8125B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408PC TT8125B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6212909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51979635097906,"sku":"6212909","price":29.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b889264a7047778d5b0648107c14f4fa_1b718e70-159a-4292-bd19-e6b0dafaf6d6.jpg?v=1789980933","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6212909-cnmg-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
