Made from silicon nitride ceramic and left uncoated, it delivers the high-temperature hardness and wear resistance needed for aggressive material removal on cast iron. The insert features an 80-degree diamond shape, a negative rake angle, a honed cutting edge, and a flat-top chip breaker. With a 0.5 inch inscribed circle and a 0.0315 inch corner radius, it suits medium to roughing passes where edge strength and thermal stability are priorities. Licensed machinists and CNC operators working in production turning environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations, with cast iron identified as the primary workpiece material. The CNMA432 geometry is common in high-speed finishing and semi-roughing passes on gray iron, ductile iron, and similar ferrous castings. It is held by a clamp and pin method, which provides rigid support under interrupted and continuous cuts. With four usable cutting edges, the insert allows efficient cost-per-edge utilization in high-volume production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon nitride ceramic substrate  -  uncoated, designed for dry high-speed cast iron machining\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (CNMA) insert shape provides strong cutting edge geometry with four usable edges\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle with honed cutting edge style for improved edge durability under load\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker configuration  -  no wiper edge, neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method supports secure seating in standard CNMA toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut up to 0.1181 inches; inscribed circle of 0.5 inches for mid-to-large insert tooling\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNMA-style toolholders accepting a 432 insert size.

Always power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque driver for the clamp screw to avoid cracking the ceramic insert body  -  do not overtighten. Ceramic inserts are brittle compared to carbide; avoid dropping or impacting the cutting edge during handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Silicon Nitride Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: FX105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (CNMA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMA432\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: 0.508 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6801915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":52070710837554,"sku":"6801915","price":198.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34a1122f89d43c1ec26523d07ef9e1fd.jpg?v=1790048653","url":"https:\/\/voomisupply.com\/products\/tungaloy-6801915-ceramic-turning-insert-cnma432-fx105","provider":"Voomi Supply","version":"1.0","type":"link"}
