Manufactured to ANSI insert code CCMT21.51 and ISO code CCMT060204, this insert features an 80-degree diamond (rhombic) shape with a positive rake angle of 8 degrees and a 7-degree relief angle. The PVD-applied ZX proprietary coating with AC520U grade delivers a balance of wear resistance and toughness suited to demanding workpiece materials. With a 1\/4-inch inscribed circle and a 1\/64-inch corner radius, this insert is configured for finishing and light machining passes where tight tolerances and surface finish quality are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning stainless steel and superalloy workpieces where controlled chip formation and edge integrity are essential. The ESU chip breaker geometry supports finishing and light machining operations, producing consistent chip control at moderate feed rates and depths of cut. The neutral hand orientation and screw-holding method make it compatible with standard CCMT-style toolholders used across a wide range of CNC turning centers and manual lathes in industrial and aerospace manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC520U PVD-coated carbide grade with ZX coating optimized for stainless steel (ISO M) and superalloys (ISO S)\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (C) with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry engineered for finishing and light machining applications\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius supports tight tolerances and fine surface finishes\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method with 0.110-inch hole diameter for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards; material grade C2\/C3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CCMT-style toolholders accepting a 21.51 ANSI size code insert.

Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as this can fracture the insert. Inspect the toolholder pocket and seating surface for chips or wear before installing a new insert. Verify feed rate and depth of cut are within the finishing and light machining parameters appropriate for this insert geometry before initiating the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT21.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT060204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code (Full)\u003c\/strong\u003e: CCMT060204N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC520U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: PVD Coated (ZX Proprietary Designation)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing, Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M), Superalloy (ISO S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 10\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19HWW0P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738016710962,"sku":"19HWW0P","price":129.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ce16ecddc2845acc0a03e54c16b0ea.jpg?v=1788795662","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hww0p-turning-insert-ccmt21-51esu-ac520u-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
