It features a 60-degree triangular shape with a positive rake angle of 5 degrees, a relief angle of 11 degrees, and a TiAlN coating applied via PVD process. The KCU10 grade is engineered for cutting steel, stainless steel, superalloys, and titanium. The LF chip breaker geometry promotes controlled chip formation during light to moderate finishing cuts. This insert is installed using a screw-on holding method and is suited for turning, facing, and boring operations. It is handled by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 4045325 is intended for use on steel, stainless steel, superalloys, and titanium workpieces where surface finish and dimensional accuracy are critical. The honed cutting edge style reduces micro-chipping on difficult-to-machine materials. Its positive rake geometry lowers cutting forces, making it well suited for thin-wall or low-rigidity workpiece setups. Applications include turning, facing, and boring in both production and prototype environments. The screw-on mounting system allows for quick, repeatable insert indexing without disturbing the toolholder setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTPGT insert style with 60-degree triangular shape and 3 cutting edges for maximum tool life per insert\u003c\/li\u003e\n\u003cli\u003eKCU10 grade with PVD TiAlN coating for heat and wear resistance on steel, stainless, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry for controlled chip evacuation during finishing operations\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 5 degrees reduces cutting forces on difficult materials and low-rigidity setups\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style minimizes micro-chipping and extends edge life\u003c\/li\u003e\n\u003cli\u003eMulti-use insert rated for turning, facing, and boring in a single geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-on style TPGT insert compatible with TPGT-style toolholders.

Power down and lock out the machine spindle before indexing or replacing the insert. Use the correct torx or hex key for the clamping screw and do not overtighten, as this can crack the carbide body. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\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\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TPGT21502LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4045325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747630383410,"sku":"4045325","price":214.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7c97eb254170c5192a31fae91e85162.jpg?v=1788883760","url":"https:\/\/voomisupply.com\/products\/kennametal-4045325-tpgt-turning-insert-tialn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
