Manufactured to ANSI insert code TPMR322 and ISO insert code TPMR160308, this triangular insert features a TiC and TiN coating applied via CVD process, delivering improved wear resistance and heat tolerance at the cutting edge. The inscribed circle measures 3\/8 inches (0.3752 inches decimal), insert thickness is 1\/8 inches (0.1250 inches decimal), and the corner radius is 1\/32 inches (0.0315 inches decimal). The insert length is 16.5 mm. Machinists and toolroom technicians install this insert in compatible TPMR-style toolholders for turning, facing, and profiling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning applications on steel and stainless steel workpiece materials, consistent with primary workpiece material codes M and P. Material grades C5, C6, and C7 indicate suitability for a range of cutting speeds and feed rates across general-purpose and semi-finishing operations. The positive side clearance and 11-degree relief angle reduce cutting forces and minimize built-up edge on ductile materials. The R-style chip breaker assists with chip control during continuous turning passes. This insert is typically used in production and job-shop environments where consistent tool life and dimensional accuracy are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiC and TiN dual coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eANSI code TPMR322 and ISO code TPMR160308 for straightforward toolholder matching\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape (T) provides three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance with 11-degree relief angle reduces cutting forces on steel and stainless\u003c\/li\u003e\n  \u003cli\u003eR-style chip breaker promotes chip control during continuous turning operations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with standard TPMR toolholder clamp systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for TPMR-style toolholders accepting ANSI size code 322 triangular carbide inserts.

Power down and de-energize the machine tool before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when securing the insert — do not overtighten the clamp screw by feel alone. Inspect the toolholder pocket and clamp for wear or damage before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMR322\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMR160308\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\u003eManufacturer Grade\u003c\/strong\u003e: TCN55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC and TiN (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3752 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.5 mm\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\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: M, P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6, C7\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 112074936\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712515703090,"sku":"112074936","price":252.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/faf0a29e7a75e1be690ead11a877566b.jpg?v=1788486382","url":"https:\/\/voomisupply.com\/products\/value-collection-112074936-turning-insert-tpmr322-tcn55","provider":"Voomi Supply","version":"1.0","type":"link"}
