It carries the ANSI insert code TPMR432 and ISO insert code TPMR220408, identifying its geometry precisely for toolholder selection. The insert features a 60-degree triangle shape with a positive side clearance and an 11-degree relief angle. A TiN (titanium nitride) coating over the C5 carbide grade improves surface hardness and wear resistance for extended tool life. The 1\/32-inch (0.0313 inch) corner radius makes it suitable for finishing and semi-finishing passes where edge definition matters. Licensed machinists and CNC operators install this insert as part of a clamp-style toolholder system.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on workpiece materials classified under primary material codes M and P, which correspond to stainless steels and carbon and alloy steels. The TPMR style geometry with positive clearance reduces cutting forces, making it well suited for both external and light-duty internal turning on ferrous materials. The R chip breaker geometry assists in chip control during moderate feed-rate operations. It is sold individually but requires a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiN coating for improved wear resistance\u003c\/li\u003e\n\u003cli\u003e60-degree triangle insert shape (ANSI code TPMR432, ISO code TPMR220408)\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle with positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e1\/32-inch (0.0313 inch) corner radius for finishing and semi-finishing applications\u003c\/li\u003e\n\u003cli\u003eR chip breaker geometry aids chip control at moderate feed rates\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with standard TPMR toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard clamp-style toolholders accepting TPMR432 geometry inserts.

Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert — do not overtighten by hand or with unrated tools. Inspect the toolholder pocket for chips or debris before seating the insert. Follow the machine tool builder and facility safety protocols when handling carbide inserts, as edges are sharp and carbide is brittle under impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMR432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMR220408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TCN55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle, 60 degrees included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: M, P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0012 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TCN17490C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715922821426,"sku":"TCN17490C","price":439.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8da93b5950de5d6aa7f55694eef0ed9a.jpg?v=1788519772","url":"https:\/\/voomisupply.com\/products\/value-collection-tcn17490c-turning-insert-tpmr432-tcn55","provider":"Voomi Supply","version":"1.0","type":"link"}
