Manufactured in grade 4425 solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability suited to steel cutting applications. It features a neutral hand orientation, a 0.156-inch inscribed circle, and a 0.0156-inch corner radius. The PF chip breaker geometry promotes controlled chip formation at moderate feeds and depths. Machinists and CNC operators install this insert during routine tooling changes or when optimizing finishing and semi-finishing passes on steel workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for steel machining, with secondary suitability for cast iron and similar ferrous materials indicated by ISO material group codes P and K. The TPMT 06 T1 04-PF geometry is a standard indexable insert format used on compatible toolholders requiring a triangular TPMT-style insert with a clamp or screw holding method. It is suited to both light production environments and high-volume CNC turning cells where consistent surface finish and tool life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 4425 solid carbide substrate for toughness and wear resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal barrier and crater wear resistance\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (TPMT) with neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry for controlled chip evacuation at moderate cutting parameters\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius suited to semi-finishing and finishing operations\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and screw-type toolholder clamping methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard TPMT-style indexable turning insert for use in compatible toolholders that accept a triangular TPMT insert with clamp or screw holding.

Seat the insert fully against the toolholder pocket before tightening the clamping screw or clamp to the toolholder manufacturer's specified procedure. Inspect the insert pocket for chips or debris before seating to prevent insert rocking or premature fracture. Index or replace the insert at the first sign of chipping, flank wear beyond acceptable limits, or degraded surface finish on the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\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: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TPMT-PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMT 06 T1 04-PF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 0.01 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8019493\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731048792370,"sku":"8019493","price":206.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35a5391bc75c919793cc740ef1de807a_08193b37-ee69-49be-9599-9e30bdb9ab21.jpg?v=1788726272","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8019493-turning-insert-tpmt-pf-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
