It carries the manufacturer catalog designation TPMT21.51ESU-AC5015S and belongs to the AC5000S series. The insert features a triangular shape with a 60-degree included angle, a 0.25 inch inscribed circle, and a 0.0157 inch corner radius. An Absotech Bronze PVD coating is applied to the AC5015S grade carbide substrate, enhancing wear resistance and thermal stability during interrupted and continuous turning operations. The insert uses a positive rake geometry and a screw-type holding method, making it compatible with standard TPMT-style toolholders. Installed by machining professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for turning non-ferrous metals and superalloys, with a secondary rating for stainless steel. The ESU chip breaker geometry promotes efficient chip evacuation and helps control built-up edge when cutting gummy or work-hardening materials. Typical applications include finish and semi-finish turning passes on aerospace components, medical parts, and precision-machined non-ferrous workpieces where tight tolerances and surface finish are critical. The neutral hand orientation allows use in both conventional and back-turning configurations depending on toolholder setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC5015S grade carbide with Absotech Bronze PVD coating for extended tool life on non-ferrous and superalloy cuts\u003c\/li\u003e\n\u003cli\u003eESU chip breaker geometry promotes clean chip evacuation on non-ferrous and work-hardening materials\u003c\/li\u003e\n\u003cli\u003ePositive rake design reduces cutting forces and heat generation at the workpiece interface\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method provides rigid, repeatable seating in TPMT-style toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports both standard and reverse turning setups\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 standards for insert geometry and identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TPMT-style insert seats. ISO code TPMT110204N-SU confirms compatibility with toolholders accepting TPMT 21.51 inserts per ANSI and ISO 13399 standards. Primary workpiece material codes N and S indicate suitability for non-ferrous metals and superalloys; secondary suitability for stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the pocket and torque the clamping screw to the toolholder manufacturer's specification using a calibrated torque driver. Inspect the insert pocket for chips or debris before seating to avoid seating errors that can damage the pocket or cause premature insert failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: TPMT21.51ESU-AC5015S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMT110204N-SU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AC5000S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\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: AC5015S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Absotech Bronze\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\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19T5WKU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51750624330034,"sku":"19T5WKU","price":22.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/708cb1fed2acb6fcd44fc7730bc314a0.jpg?v=1788917507","url":"https:\/\/voomisupply.com\/products\/sumitomo-19t5wku-turning-insert-carbide-ac5015s-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
