The insert is manufactured from carbide and carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for extended wear resistance and thermal stability at the cutting edge. The triangular insert shape provides 6 usable cutting edges, and the M3 chip breaker geometry features a chamfered and honed edge prep suited for interrupted and continuous cuts. The 0.5000-inch inscribed circle and 0.0315-inch corner radius place this insert in the mid-range of general turning applications. Licensed HVAC, plumbing, and electrical tradespeople do not typically use this product — it is installed by machinists and CNC operators in metal cutting operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in negative-rake TNMG-style toolholders in turning centers and CNC lathes. Primary workpiece material is steel (ISO material group P: P20, P30, P40). Secondary workpiece material is stainless steel (ISO material group M). Applicable operations include turning, facing, boring, and back turning. The M3 chip breaker geometry is optimized for medium cutting conditions with moderate feeds and depths of cut. Maximum depth of cut is 0.7874 inches. The insert seats via clamp, pin, or lever-lock holding methods depending on the toolholder configuration used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating — TiCN, Al2O3, and Cr — for wear resistance on steel and stainless\u003c\/li\u003e\n  \u003cli\u003e6 cutting edges per insert from the triangular (T) insert shape, maximizing cost per edge\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker with chamfered and honed edge prep for reliable chip control on medium cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry with N clearance code for rigid, stable toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eRated for turning, facing, boring, and back turning operations\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO indexable insert standards; ISO code TNMG220408-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in negative-rake TNMG-style toolholders compatible with the TNMG432 insert size (insert size code 432).

Seat the insert fully against the pocket locating surfaces before engaging the clamping mechanism — do not force the clamp onto a misaligned insert. Inspect the insert pocket for wear, chips, or debris before seating a new edge. Consult the toolholder manufacturer's torque specification for the clamping screw; do not use an impact driver.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMG432-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG220408-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TNMG-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP3501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8661 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N (0-degree relief angle)\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: M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P — P20, P30, P40)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\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: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 0.47 x 1.97 x 4.33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03093894\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563819106610,"sku":"03093894","price":369.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8db51e312dbc8a25ac6a668459baeb01_c4805d50-ae78-4472-98ca-114898849452.jpg?v=1786504105","url":"https:\/\/voomisupply.com\/products\/seco-03093894-turning-insert-tnmg432-m3-tp3501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
