The insert features a 55-degree diamond (rhombic) shape, a 0.25-inch inscribed circle, and a 0.0079-inch corner radius. A TiAlN PVD coating delivers high wear resistance across a range of workpiece materials. The positive rake angle of 15 degrees and honed cutting edge reduce cutting forces during light finishing passes. Licensed machinists and CNC operators install this insert in screw-on toolholders for turning, facing, boring, back turning, and back boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing cuts on steel, stainless steel, superalloys, titanium, cast iron, aluminum, and hardened materials, corresponding to ISO material groups P, M, K, N, S, and H. The HP chip breaker geometry is optimized for finishing operations where tight tolerances and fine surface finish are required. The neutral hand orientation makes it adaptable across compatible screw-on DCGT-style toolholders. Its maximum depth of cut reaches 0.2033 inches, making it appropriate for light to moderate material removal in high-precision turning scenarios common in aerospace, medical, and general machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDCGT21505HP geometry with 55-degree diamond shape and positive 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003eKCU10 grade with TiAlN PVD coating for high wear resistance on steel, stainless steel, and superalloys\u003c\/li\u003e\n\u003cli\u003eHP chip breaker optimized for finishing operations with positive 15-degree rake angle\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge for reduced cutting forces and improved surface finish\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method with neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for screw-on DCGT-style toolholders accepting DCGT21505 geometry inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and secure with the clamping screw to the toolholder manufacturer's specified method before resuming operation. Inspect the cutting edge and seating pocket for chips or debris before each insert change to ensure accurate positioning and safe cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCGT21505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCGT070202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6104 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: 0.2033 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HP (Finishing)\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\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium, Cast Iron, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 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: 4045237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733227209010,"sku":"4045237","price":202.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85dae1458384cfbed9f0206d5a0bcb60.jpg?v=1788753036","url":"https:\/\/voomisupply.com\/products\/kennametal-4045237-dcgt21505hp-kcu10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
