Manufactured to ISO\/ANSI standard TPG432T00320, this insert carries a grade A65 ceramic substrate composed of Al2O3 and TiC, delivering the hardness and thermal resistance required for cutting cast iron and hard materials. The insert features a 0.5-inch inscribed circle, a 3\/16-inch thickness, and a 1\/32-inch corner radius. With three cutting edges and a positive rake geometry, it provides efficient chip formation and extended tool life in demanding turning applications. Licensed machinists and CNC tooling professionals use this insert in production environments where ceramic grades outperform carbide.\u003c\/p\u003e\u003cp\u003eThe TCR89310 is suited for external turning, facing, boring, and chamfering operations on cast iron and hard workpiece materials. It fits toolholders designed for the TPG insert style with a clamp holding method. The ISOI series designation places it within a standardized insert family, making it straightforward to match with compatible clamp-style toolholders used in CNC turning centers and manual lathes in both job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic Al2O3 TiC substrate in grade A65 for high-hardness and high-temperature cutting\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape with 60-degree included angle and three usable cutting edges\u003c\/li\u003e\n\u003cli\u003e0.5-inch (0.5000 inch) inscribed circle with 1\/32-inch (0.0313 inch) corner radius\u003c\/li\u003e\n\u003cli\u003ePositive rake, neutral hand geometry suitable for external turning, facing, boring, and chamfering\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with standard TPG toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO code TPG432T00320\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style TPG insert toolholders conforming to ANSI and ISO standards.

Power down and lock out the machine spindle before seating or indexing the insert. Verify the toolholder pocket and clamp are clean and free of chips before securing the insert. Always index to a fresh cutting edge rather than continuing on a worn edge to prevent workpiece damage and toolholder wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPG432T00320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: A65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic (Al2O3 TiC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12 mm (0.8668 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\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: P (11 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2889 inches\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: Cast Iron, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K01, K10, H01, H10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Boring, Chamfering, External Turning, Facing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISOI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.13 pounds\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: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TCR89310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51748498702642,"sku":"TCR89310","price":299.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dade6fe03ccc09c27ca02969a341d4ab.jpg?v=1788894490","url":"https:\/\/voomisupply.com\/products\/kyocera-tcr89310-ceramic-turning-insert-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
