It features a solid carbide substrate with a TiAlN PVD coating applied under the AH120 grade, delivering high wear resistance and edge stability across a broad range of workpiece materials. The insert carries a diamond 80-degree geometry with a negative rake angle of -6 degrees, a 1\/64-inch corner radius, and a TM chip breaker designed to control chip flow during turning, facing, and boring operations. Licensed HVAC techs are not the audience here  -  this insert is installed by machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe CNMG431TM AH120 is suited for turning, facing, and boring applications on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It carries ISO material grade designations P15, P25, M15, M25, K15, K30, S10, and S25, making it a versatile choice across a wide range of material hardness levels. The neutral hand orientation means it can be used in standard right-hand or left-hand toolholders that accept CNMG-style inserts. With four cutting edges per insert, it offers good cost-per-edge value in production turning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAH120 carbide grade with TiAlN PVD coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eDiamond 80-degree insert shape with negative rake provides strong cutting edge and versatile entry angles\u003c\/li\u003e\n  \u003cli\u003eTM chip breaker geometry supports chip control during turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code CNMG 431 TM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders that accept a 1\/2-inch inscribed circle insert with clamp or pin holding.

Use the appropriate CNMG toolholder torque procedure per the toolholder manufacturer's documentation when seating the clamp or pin. Inspect the insert pocket and seating surface for chips or debris before installing a new edge. Do not exceed the maximum depth of cut of 0.1969 inches as noted in the published specifications.\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\u003eISO Code\u003c\/strong\u003e: CNMG 431 TM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -6 degrees (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5080 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TM\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P15, P25, M15, M25, K15, K30, S10, S25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6811615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972087808306,"sku":"6811615","price":217.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a2904a0f6cca88ebffca9eb4e1bfb9e_d3658872-32c9-4034-9221-6a96551a8da4.jpg?v=1789962327","url":"https:\/\/voomisupply.com\/products\/tungaloy-6811615-cnmg431tm-ah120-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
