Manufactured to the ANSI insert code SPMR421 and ISO code SPMR120304, this insert features a square shape (S) with a 90-degree included angle and an 11-degree relief angle. The insert carries a TiN (titanium nitride) coating under manufacturer grade TCN55, which improves surface hardness and extends tool life during ferrous and non-ferrous metal turning. It has a 0.5-inch inscribed circle and a 1\/64-inch (0.0156 inch) corner radius, making it well suited to general-purpose turning profiles.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in production and job-shop turning environments where consistent chip control and dimensional accuracy are required. It is compatible with toolholders designed for SPMR-style inserts with a clamp holding method. The positive side clearance geometry reduces cutting forces and heat buildup. Primary workpiece material codes M and P indicate suitability for steel and stainless steel applications. It ships individually but is subject to a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiN coating for improved wear resistance on grade TCN55\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and positive side clearance (Clearance Code P)\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle for robust edge support across standard toolholder systems\u003c\/li\u003e\n\u003cli\u003e1\/64-inch (0.0156 inch) corner radius for general-purpose turning profiles\u003c\/li\u003e\n\u003cli\u003eChip breaker designation R for controlled chip formation during continuous cuts\u003c\/li\u003e\n\u003cli\u003eTolerance Code M and Insert Style SPMR for repeatable indexing in clamp-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with toolholders accepting SPMR-style turning inserts using a clamp holding method.

Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and clamp screws specified by the toolholder manufacturer when securing the insert. Inspect the seating pocket for chips or debris before installing a new insert to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SPMR421\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SPMR120304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPMR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TCN55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: M, P (Stainless Steel, Carbon and Alloy Steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (Minimum Order Quantity: 10)\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: TCN19330K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696279912754,"sku":"TCN19330K","price":366.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/145b14d97a789846d3373c8eef7a7684.jpg?v=1788340964","url":"https:\/\/voomisupply.com\/products\/value-collection-tcn19330k-turning-insert-spmr421-tcn55","provider":"Voomi Supply","version":"1.0","type":"link"}
