Featuring a TiAlN coating applied via PVD process, this insert carries the manufacturer grade AH120 and is built for negative rake angle operation at -20 degrees. The 80-degree diamond insert shape (CNMG) provides two usable cutting edges per side for a total of four cutting edges. With a 3\/4-inch inscribed circle, a 0.76-inch insert length, and a 1\/16-inch corner radius, this insert handles turning, facing, and boring operations with a chamfered and honed cutting edge style for controlled entry and edge stability.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. It fits within material grades P15, P25, M15, M25, K15, K30, S10, and S25, making it a versatile choice for general and interrupted-cut turning applications in both production and job-shop environments. The TH chip breaker geometry is optimized for consistent chip control across these material groups. Installation is handled by clamp and pin holding methods, compatible with standard CNMG-style toolholders. This insert is sold individually but subject to a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating with AH120 grade for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 total cutting edges for cost-effective edge utilization\u003c\/li\u003e\n  \u003cli\u003eTH chip breaker geometry supports consistent chip control in turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style reduces notch wear and improves edge stability\u003c\/li\u003e\n  \u003cli\u003eNegative rake design (-20 degrees) provides strong edge support in interrupted and heavy cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods for secure seating in CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNMG-style toolholders accepting a 3\/4-inch inscribed circle, 1\/4-inch thick insert with a 0.312-inch hole diameter.

Before changing inserts, shut down spindle rotation and engage machine locks or e-stop protocols per the machine tool manufacturer guidelines. Seat the insert fully against the toolholder pocket and torque the clamp or pin fastener per the toolholder manufacturer specification. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper contact and prevent premature edge failure.\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 644TH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG-TH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\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: Solid 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\u003eChip Breaker\u003c\/strong\u003e: TH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.76 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inches (0.0629 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2362 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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -20 degrees\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\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 Grades\u003c\/strong\u003e: P15, P25, M15, M25, K15, K30, S10, S25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\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: 0.04 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: 6802314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52058884342066,"sku":"6802314","price":421.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a792e1151cac8f7e4e03f6df8fe93a8b_47effa42-30a1-4d53-89f4-0dda4a392ea7.jpg?v=1790039926","url":"https:\/\/voomisupply.com\/products\/tungaloy-6802314-turning-insert-cnmg644th-ah120-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
