The C diamond shape (80-degree included angle) combined with N-type clearance (0 degrees) and M-tolerance class provides a rigid, predictable cutting geometry suited for medium-duty roughing and semi-finishing passes. The G-style chip breaker geometry promotes chip control across a range of depths of cut and feed rates. These inserts are installed by machinists and CNC lathe operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning applications requiring a balance of edge strength and chip control. The CNMG 643 size designation indicates a 0.750-inch inscribed circle diameter and a 0.250-inch insert thickness. The IC20 carbide substrate is formulated for general-purpose turning. Typical applications include machining steel, alloy steel, and other medium-hardness ferrous workpiece materials at moderate cutting parameters. This insert is sold individually but must be ordered in multiples of 10.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC-shape (80-degree diamond) geometry delivers strong cutting edge for roughing and semi-finishing\u003c\/li\u003e\n  \u003cli\u003eIC20 carbide grade provides wear resistance in general-purpose turning of ferrous materials\u003c\/li\u003e\n  \u003cli\u003eG chip breaker geometry promotes consistent chip evacuation across varied feed and depth conditions\u003c\/li\u003e\n  \u003cli\u003eM-tolerance class ensures dimensional consistency and repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eN-type clearance (0-degree flank) maximizes edge strength for interrupted or heavy cuts\u003c\/li\u003e\n  \u003cli\u003eCNMG 643 industry-standard form factor fits compatible CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard production insert for CNMG 643 indexable turning toolholders that accept 80-degree diamond inserts with N clearance and M tolerance.

Use the appropriate torque wrench and manufacturer-specified seating hardware for the toolholder to avoid cracking the insert or damaging the pocket. Inspect the insert seat and clamp for chips or wear before indexing to a fresh edge. Follow applicable shop safety procedures and machine-specific lockout\/tagout protocols during any tooling change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG 643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C (80-degree diamond)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5500221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51751249019186,"sku":"5500221","price":365.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29131ad5cefe3fbc548a8114726e7230.jpg?v=1788922462","url":"https:\/\/voomisupply.com\/products\/iscar-5500221-turning-insert-cnmg-643-ic20","provider":"Voomi Supply","version":"1.0","type":"link"}
