Featuring a round insert shape (Shape Code R) with a 1\/2 inch inscribed circle and 5\/16 inch insert thickness, this insert carries ISO Code RNGN120700E in grade 6060. The clearance code is N (zero-degree relief angle) and the tolerance code is G, indicating a ground insert held by a clamp-style toolholder. Grade 6060 is an uncoated carbide grade suited for applications where a bright, uncoated cutting edge is required. Machinists and CNC operators install this insert into compatible round-pocket toolholders as part of a precision external or internal turning setup.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations in machining environments where consistent edge geometry and dimensional accuracy are critical. The round shape distributes cutting forces evenly across the edge, making it appropriate for both roughing and finishing passes depending on feed rate and depth of cut selections. The RNGN insert style is commonly used on production turning equipment in job shops, aerospace, and general-purpose machining facilities. Install size code 45 corresponds to the 12.70 mm inscribed circle class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (Code R) with 1\/2 inch (12.70 mm) inscribed circle for full 360-degree usable edge\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate, grade 6060, bright\/uncoated finish\u003c\/li\u003e\n  \u003cli\u003eInsert thickness of 5\/16 inch (7.94 mm) for stable seating in clamp-style toolholders\u003c\/li\u003e\n  \u003cli\u003eZero-degree relief angle (Clearance Code N) with G tolerance for ground precision fit\u003c\/li\u003e\n  \u003cli\u003eNo chip breaker geometry — flat top for unrestricted chip flow in specialty applications\u003c\/li\u003e\n  \u003cli\u003eISO designation RNGN120700E 6060 for direct cross-reference to compatible toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in clamp-style round-insert toolholders accepting RNGN-style inserts with a 1\/2 inch inscribed circle and insert size code 45.

Always bring the machine spindle to a full stop and engage the E-stop before indexing or replacing an insert. Use the manufacturer-specified torque for the clamping screw — refer to the toolholder documentation for the correct value, as this insert data does not include a torque specification. Inspect the toolholder pocket for wear, debris, or damage before seating the new insert, as a compromised pocket will affect edge accuracy and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNGN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RNGN120700E 6060\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round (Code R)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 6060\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/16 inch (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 5\/16 inch (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code)\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.58 inches W x 0.53 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5741277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732349583666,"sku":"5741277","price":324.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f86676cb0ecb2e1a5f24a28a0b4e70c.jpg?v=1788741927","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5741277-round-turning-insert-1-2-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
