It carries the AC8025P manufacturer grade and features Absotech CVD coating, which provides wear resistance and thermal stability during interrupted and continuous cuts. The insert geometry is triangular with a 60-degree included angle, a neutral hand orientation, and a positive rake configuration. With a corner radius of 0.031 inches and an inscribed circle of 0.25 inches, this insert suits finishing and semi-finishing passes where dimensional accuracy and surface finish are priorities. Licensed machinists and CNC lathe operators install this insert in TPMT-compatible toolholders using the screw-clamping method.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning steel in CNC and manual lathe applications. The ESU chip breaker geometry is optimized for steel cutting, managing chip flow during moderate to high feed rates. The TPMT style with clearance code P and tolerance code M makes it a standard fit for production turning environments, including job shops and manufacturing facilities running ISO and ANSI-spec tooling systems. It is suitable for both light roughing and finishing cuts on carbon steels and alloy steels where the primary workpiece material code is P.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC8025P grade with Absotech CVD coating for wear and heat resistance on steel\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry designed for controlled chip flow on steel workpieces\u003c\/li\u003e\n  \u003cli\u003ePositive rake, neutral hand configuration reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI code TPMT222ESU and ISO code TPMT110308N-SU for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape with 60-degree included angle provides three usable cutting edges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPMT-series screw-clamp toolholders conforming to ANSI and ISO 13399 standards.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specification — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris 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: TPMT222ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMT110308N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC8025P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Absotech (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\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\u003eChip Breaker\u003c\/strong\u003e: ESU\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: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.134 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\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: 0.01 pounds\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: 19P7109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51733272854834,"sku":"19P7109","price":24.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f55d126e747c80b41be083fcffc79a67.jpg?v=1788753456","url":"https:\/\/voomisupply.com\/products\/sumitomo-19p7109-turning-insert-tpmt222esu-ac8025p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
