It carries the ANSI designation DCMT32.50.5ESU and ISO designation DCMT11T302N-SU, placing it in the DC series. The insert features a dual PVD coating — TiAlN and AlCrN — marketed under Sumitomo's Super ZX coating designation, which is engineered for heat resistance and extended tool life in demanding cutting applications. The diamond (55-degree) insert shape, positive rake geometry, and ESU chip breaker make this insert well-suited for finishing and semi-finishing operations where chip control and surface finish are critical priorities. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning applications involving stainless steel and superalloy workpiece materials (ISO material codes M and S). The positive rake angle of 8 degrees and 7-degree relief angle reduce cutting forces, making the insert a practical choice for thin-wall or difficult-to-machine components. It is held in the toolholder via screw clamping, consistent with standard DCMT-style toolholders. This insert is sold individually, with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with dual PVD coating: TiAlN and AlCrN (Super ZX designation)\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry optimized for stainless steel and superalloy finishing\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert holding method compatible with standard DCMT toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards for interchangeability and tool data integration\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle with 0.0078 inch corner radius for fine-finish turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DCMT-style screw-clamp turning toolholders.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to toolholder manufacturer specifications — do not overtighten, as this can fracture the carbide insert. Inspect the toolholder pocket for chips or wear before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DCMT32.50.5ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT11T302N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 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\u003c\/strong\u003e: TiAlN \/ AlCrN (Super ZX, PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4567 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 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: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloy (ISO M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 19HWW5F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51746685780274,"sku":"19HWW5F","price":215.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d10136e45dc9b03f81eeea0a19310f33_25b13320-9a2a-4f6a-b23e-667813bca695.jpg?v=1788872694","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hww5f-turning-insert-ac520u-diamond-3-8-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
