The insert features a multilayer MTCVD-applied coating of TiCN, Al2O3, and TiN, which provides a hardwearing surface suited to both roughing and medium machining passes. Geometry is right-hand, negative side clearance, with a positive rake and a 60-degree triangular shape. The M3P chip breaker geometry manages chip control across a range of feed rates and depths. At 22 millimeters in length with a 0.8 millimeter corner radius and a 12.7 millimeter inscribed circle, this insert seats into standard TNMG-style toolholders used throughout production turning environments.\u003c\/p\u003e\u003cp\u003eThe IC8250 grade is engineered for steel (P) applications requiring high wear resistance to high toughness, and for stainless steel (M) applications requiring high wear resistance to moderate wear resistance and toughness. Typical installations include CNC turning centers and manual lathes running continuous or interrupted cuts in carbon steel, alloy steel, and austenitic stainless steel. The M3P chip breaker handles roughing and medium machining, making this insert a practical choice for material removal passes where chip evacuation and insert life are both priorities. Maximum rated depth of cut is 6.60 millimeters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC8250 grade with MTCVD-applied TiCN, Al2O3, TiN multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eM3P chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e60-degree triangle (T) insert shape with negative side clearance and positive rake\u003c\/li\u003e\n\u003cli\u003e0.8 millimeter corner radius for a balance between edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eCompatible with P (steel) and M (stainless steel) primary workpiece material groups per ISO designation\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard TNMG432 (ISO: TNMG 220408) style toolholders accepting negative-rake triangular inserts with a 0.5 inch inscribed circle.

Secure the insert in a TNMG-compatible toolholder using the appropriate clamping screw and torque driver per the toolholder manufacturer's specification. Inspect the insert pocket for chips or debris before seating the insert. Index to a fresh cutting edge or replace the insert when flank wear, chipping, or surface finish degradation is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG220408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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: M3P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 22.00 millimeters (0.866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 millimeters (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 millimeters (0.187 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 millimeters (0.031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.60 millimeters (0.260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steel), M (Stainless Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5567505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730483609906,"sku":"5567505","price":277.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5189226c5fa5903d16d817848da5455.jpg?v=1788718254","url":"https:\/\/voomisupply.com\/products\/iscar-5567505-tnmg432-turning-insert-ic8250-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
