Carrying the ANSI designation TPG221 and ISO designation TPG110304, it belongs to the KENDEX series. The insert features a 60-degree included angle, a 1\/4-inch inscribed circle, and a 1\/64-inch corner radius. The K313 grade is an uncoated bright carbide formulated for high wear resistance across a range of workpiece materials including non-ferrous metals, stainless steel, cast iron, and superalloys. The flat-top chip breaker geometry and positive rake angle promote clean chip flow and reduced cutting forces. Licensed machinists and CNC operators install this insert in compatible clamp-style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both production and job-shop environments. Its positive side clearance and honed cutting edge make it well-matched for finishing and semi-finishing passes on aluminum, non-ferrous metals, stainless steel, cast iron, and titanium-based superalloys. The three available cutting edges extend tool life between holder changes. Maximum recommended depth of cut is 0.049 inches (1.25 mm), positioning this insert for light-to-moderate material removal rather than heavy roughing. It is appropriate for both residential-shop and industrial-floor CNC turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code TPG221, ISO code TPG110304 — KENDEX series for standardized toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eK313 uncoated bright carbide grade with high wear resistance for stainless steel, cast iron, aluminum, and superalloys\u003c\/li\u003e\n\u003cli\u003e60-degree triangular shape provides three usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003ePositive rake angle and flat-top chip breaker support clean chip evacuation on light-to-moderate cuts\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent edge integrity on finishing passes\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.049 inches (1.25 mm) — optimized for finishing and semi-finishing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style toolholders that accept TPG221 triangular inserts per ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque driver or clamp screw per the toolholder manufacturer specifications — do not overtighten the clamp, as this can chip the insert or damage the pocket seat. Inspect the toolholder pocket for debris or wear before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPG221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPG110304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.433 inches (11.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.049 inches (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Side Clearance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K313\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Material Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0055 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1183203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727514730802,"sku":"1183203","price":148.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6473b4c3a08f45d2c011d9eadb5c42e4.jpg?v=1788678764","url":"https:\/\/voomisupply.com\/products\/kennametal-1183203-tpg221-k313-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
