It features a diamond-shaped insert body with an 80-degree included angle, a 0.40 mm (0.0157 inch) corner radius, and an AlTiN coating applied over a KCU10B carbide substrate. The neutral hand orientation and G-tolerance classification make it suitable for close-tolerance finishing and semi-finishing passes. With four available cutting edges, this insert delivers consistent performance in production turning environments where tool change frequency and cost-per-edge are primary concerns for machinists and tooling engineers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations in job shops, production machining cells, and aerospace or general metalworking environments. The CNGP geometry with a P-style chip breaker is commonly applied to ferrous and non-ferrous materials where controlled chip evacuation and surface finish repeatability are required. The AlTiN coating provides elevated heat resistance, making it appropriate for dry or minimal-lubrication cutting conditions at moderate to high cutting speeds. Licensed machinists and CNC programmers will find this insert appropriate for medium-depth finishing cuts on steel and alloy workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiamond insert shape with 80-degree included angle for strong cutting edge geometry\u003c\/li\u003e\n\u003cli\u003eAlTiN coating over KCU10B carbide grade for heat resistance in dry cutting applications\u003c\/li\u003e\n\u003cli\u003e0.40 mm (0.0157 inch) corner radius suitable for semi-finishing and finishing passes\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eG-tolerance classification ensures dimensional consistency for close-tolerance turning\u003c\/li\u003e\n\u003cli\u003eP-style chip breaker promotes controlled chip formation during turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGP-compatible turning toolholders with a C-style insert seat, neutral hand orientation, and a 1\/2-inch inscribed circle seating designation.

Power down and lock out the machine before indexing or replacing inserts. Use a torque wrench appropriate for carbide insert clamping screws and follow the toolholder manufacturer's clamping specifications. Avoid impact or dropping the insert, as carbide is brittle and susceptible to chipping from mechanical shock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7090564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730200133938,"sku":"7090564","price":185.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8705ac9e9201800a6e2c0cc5a541b49e_117d1f2f-f0f9-44c3-8b08-812bf539f567.jpg?v=1788713216","url":"https:\/\/voomisupply.com\/products\/kennametal-7090564-cngp-turning-insert-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
