Manufactured to ANSI insert code RPGX35 and ISO code RPGX090700T6, this insert carries the TC3030 manufacturer grade, which is engineered for moderate wear resistance and toughness through high toughness in superalloy and titanium workpiece materials. With a 3\/8 inch inscribed circle and a 3\/16 inch corner radius, the insert geometry supports consistent, stable cutting in interrupted and continuous cuts alike. It ships bright and uncoated, with a positive rake and positive side clearance. Licensed machinists and CNC programmers working in aerospace, medical, and energy sectors will find this insert suited to their material requirements.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on primary workpiece materials coded S under ISO classification, which covers superalloys and titanium alloys. The RPGX style features a chip breaker designation of X and is held by screw mounting, making it compatible with toolholders designed for round screw-on inserts. Typical applications include roughing and semi-finishing passes on nickel-base superalloys, cobalt alloys, and titanium where ceramic cutting grades offer a speed and productivity advantage over carbide. The neutral hand configuration allows the insert to run in either direction depending on toolholder orientation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTC3030 ceramic grade rated for superalloys and titanium, primary workpiece material code S\u003c\/li\u003e\n\u003cli\u003eRound insert shape with 3\/8 inch inscribed circle and 3\/16 inch corner radius for stable engagement\u003c\/li\u003e\n\u003cli\u003ePositive rake and positive side clearance geometry reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish preserves as-ground edge sharpness out of the box\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting (clearance code P, tolerance code G) for repeatable indexing\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert maximizes value per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for toolholders accepting round RPGX-style screw-on inserts with a 3\/8 inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the manufacturer-specified torque wrench for the insert clamping screw to avoid cracking the ceramic substrate. Ceramic inserts are brittle compared to carbide; handle edges carefully and avoid impact or dropping. Verify toolholder pocket condition and seating surface cleanliness before indexing to a fresh cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RPGX35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RPGX090700T6 TC3030\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RPGX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TC3030\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: X\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6158920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52016368550194,"sku":"6158920","price":481.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f257fe7d436840cfcd288a658135d17.jpg?v=1790008616","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6158920-rpgx-ceramic-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
