It features a parallelogram shape with a 55-degree included angle, a 0.5-inch inscribed circle, and a corner radius of 0.0312 inches (0.79 mm). The insert carries a positive rake angle of 5 degrees and an 8-degree relief angle, supporting aggressive chip evacuation during profiling passes. Licensed machinists and CNC lathe operators install this insert in Top Notch-series toolholders for external profiling and contour turning operations on a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for profiling and turning applications across a broad material spectrum including steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. The neutral hand orientation and clamp-style holding method make it compatible with standard Top Notch-series clamping systems commonly found in production turning environments, both light-duty finishing and moderate-depth roughing profiles. It is appropriate for job shops and production facilities running CNC lathes and manual turning centers where consistent edge geometry on contoured workpieces is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating provides heat resistance and extended tool life when cutting steel, stainless steel, and superalloys\u003c\/li\u003e\n\u003cli\u003eParallelogram (DPGR) insert geometry with 55-degree included angle optimized for profiling and contour turning\u003c\/li\u003e\n\u003cli\u003ePositive rake (5 degrees) reduces cutting forces and supports cleaner chip formation on difficult materials\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0312 inches (0.79 mm) delivers precise surface finish on contoured features\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut up to 0.2035 inches suits both finishing and light roughing passes\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert extend usable life before replacement\u003c\/li\u003e\n\u003cli\u003eFine-grain carbide substrate in KCU25 grade balances toughness and wear resistance across ISO material groups P, M, K, N, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert conforming to DPGR432 and ISO code DCGR150408 standards, for use in Top Notch-series clamp-style toolholders.

Seat the insert firmly against the toolholder pocket before engaging the clamp; do not force a misaligned insert. Inspect the insert pocket for chips or debris before seating to ensure proper contact and geometry transfer. Follow the toolholder manufacturer's clamping torque specifications for the Top Notch-series clamping screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DPGR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\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\u003eThickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length \/ Side Length\u003c\/strong\u003e: 0.6104 inches (15.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCGR150408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Profiling, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.032 pounds\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: 5\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: 4050522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747082010930,"sku":"4050522","price":265.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84811d7a75eab100d4983907ff28aeb1.jpg?v=1788875861","url":"https:\/\/voomisupply.com\/products\/kennametal-4050522-dpgr432-kcu25-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
