It features a multilayer PVD coating sequence of TiN, TiCN, and TiN applied over a solid carbide substrate, delivering a combination of wear resistance and edge toughness suited to interrupted and continuous milling operations. The insert measures 0.8661 inches in length and 0.1874 inches in thickness, with an inscribed circle of 0.5000 inches. A 60-degree included angle and an 11-degree relief angle define the cutting geometry. The insert is right-hand oriented and is held in place by a screw-clamp method. Licensed machinists and CNC tooling technicians are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThe TPKN2204PDTR insert is designed for milling applications on steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. It is suited for face milling, shoulder milling, and similar operations where a triangular insert geometry is called for. The KC725M grade positions it as a versatile choice across varying cutting conditions in those material families, from roughing passes on carbon steel to finishing cuts on harder stainless and nickel-based alloys. These inserts are sold in minimum order quantities of 5, with individual package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer PVD coating: TiN outer, TiCN mid, TiN base for enhanced wear resistance\u003c\/li\u003e\n  \u003cli\u003eTriangular TPKN insert style with 60-degree included angle and 11-degree relief for positive cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation with screw-clamp holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eKC725M manufacturer grade rated for steel, stainless steel, superalloys, and titanium (ISO P, M, S)\u003c\/li\u003e\n  \u003cli\u003eISO designation TPKN2204PDTR for direct cross-reference with compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.5000 inches; thickness 0.1874 inches for use in standard TPKN-series pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-clamp toolholders accepting TPKN-series triangular inserts with an insert size code of 43 and an inscribed circle of 0.5000 inches.

Seat the insert firmly into the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using a calibrated torque driver. Inspect the pocket and seating surfaces for chips or debris before installing a new insert. Never use an insert that shows edge chipping, cracks, or delamination of the coating, as a compromised insert can fracture under cutting loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: TPKN2204PDTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC725M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPKN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\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 \/ TiCN \/ TiN (Multilayer PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8661 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade (ISO)\u003c\/strong\u003e: C5, C6, C7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0267 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1159581\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737499271474,"sku":"1159581","price":343.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b7c8cf1886b3b58314ae0c285f83f54.jpg?v=1788789329","url":"https:\/\/voomisupply.com\/products\/kennametal-1159581-milling-insert-tpkn2204pdtr-kc725m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
