It carries the CCMT insert style with an 80-degree diamond shape, a 1\/4 inch inscribed circle, and a corner radius of 0.0078 inches. The insert is coated using a PVD process with Sumitomo's proprietary ZX coating under the AC520U manufacturer grade. The ESU chip breaker geometry promotes positive rake cutting, reducing cutting forces and improving chip control. With a neutral hand orientation, this insert suits a wide range of turning toolholders. Machinists and CNC operators working in production or job-shop environments install these inserts as indexable cutting edges on standard turning tools.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on stainless steel and superalloy workpiece materials, classified under ISO material groups M and S. The positive rake angle of 8 degrees and the 7-degree relief angle support clean, efficient cuts on these difficult-to-machine materials. The ESU chip breaker is designed to manage stringy chips common in stainless and high-temperature alloy turning. It is appropriate for finishing and light semi-finishing passes where edge sharpness and surface finish matter. This insert is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCCMT insert style with 80-degree diamond shape and positive rake geometry\u003c\/li\u003e\n\u003cli\u003eAC520U grade with PVD-applied ZX proprietary coating for extended tool life on difficult materials\u003c\/li\u003e\n\u003cli\u003eESU chip breaker geometry controls chips in stainless steel and superalloy turning\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0078 inches supports fine surface finish in light finishing passes\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eScrew-holding method with 0.1100 inch hole diameter for secure insert clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMT-style screw-on turning toolholders accepting a 1\/4 inch inscribed circle insert.

Ensure the machine spindle is fully stopped and the toolholder is secured before indexing or replacing the insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specification — do not overtighten. Inspect the insert seat and chip breaker pocket for debris before seating the 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: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0078 inches\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: 3\/32 inch (0.0937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1100 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\u003eManufacturer Grade\u003c\/strong\u003e: AC520U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary Coating\u003c\/strong\u003e: ZX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT060202N-SU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloy (ISO M, S)\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: 0.025 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19HWW05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51738896498994,"sku":"19HWW05","price":131.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/620a2166782f02cab4129a84a5eb29a7.jpg?v=1788806381","url":"https:\/\/voomisupply.com\/products\/sumitomo-19hww05-turning-insert-ccmt-80-diamond-ac520u","provider":"Voomi Supply","version":"1.0","type":"link"}
