It carries the TT8125B manufacturer grade with a multilayer CVD coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability at the cutting edge. The insert features a diamond shape with an 80-degree included angle, a 0.0310-inch corner radius, and a negative rake geometry. Four cutting edges are available per insert, and the PC chip breaker geometry controls chip flow across a range of feed and depth conditions. Licensed machinists and CNC turning specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external and internal turning, facing, and profiling operations on steel in production machining environments, both job-shop and high-volume. The PC chip breaker and neutral hand make it adaptable to a range of turning centers and engine lathes. It is held in place via a top-clamp toolholder system and fits standard CNMG 332 pocket geometry. Maximum depth of cut is 0.1250 inches, and the inscribed circle diameter is 0.3750 inches, making it appropriate for medium to light material removal passes on ferrous workpieces classified under ISO material group P.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTT8125B grade with CVD multilayer TiCN\/Al2O3\/TiN coating for steel cutting performance\u003c\/li\u003e\n  \u003cli\u003eDiamond insert shape with 80-degree included angle provides a strong cutting edge\u003c\/li\u003e\n  \u003cli\u003ePC chip breaker geometry for controlled chip evacuation in steel turning\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert to maximize tooling value\u003c\/li\u003e\n  \u003cli\u003eNegative rake and 0-degree relief angle optimized for clamp-style CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert for use in both right-hand and left-hand toolholder applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG 332 top-clamp toolholders.

Use a torque wrench appropriate for the toolholder clamp screw to avoid over-tightening, which can chip the insert or damage the pocket seating surface. Inspect the pocket and clamp for wear or debris before seating a new insert. Follow the machine manufacturer and toolholder manufacturer guidelines for clamp torque and insert orientation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT8125B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3820 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\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\u003eCoating\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\u003eChip Breaker\u003c\/strong\u003e: PC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 332\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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 (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG332PCTT8125B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG090408PC TT8125B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 6212379\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52064057983282,"sku":"6212379","price":162.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b889264a7047778d5b0648107c14f4fa_0cff9ff9-f956-4641-ba1a-e3ff3a395f80.jpg?v=1790043768","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6212379-cnmg-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
