Carrying the ANSI designation TPMT21.52ESU and ISO code TPMT110208N-SU, this insert features a triangular shape with a 60-degree included angle, a positive rake angle of 8 degrees, and an 11-degree relief angle. The AC820P grade substrate is CVD-coated with Al2O3, delivering high wear resistance across a range from moderate to high-wear cutting conditions. With a 1\/32-inch corner radius and a 1\/4-inch inscribed circle, this insert is sized for finishing and light machining passes on steel and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 19RJWC2 is suited for finishing and light machining operations on steel (ISO P) and cast iron (ISO K) workpieces. The ESU chip breaker geometry is engineered for controlled chip formation at light depths of cut and moderate feed rates, making this insert appropriate for close-tolerance turning where surface finish and dimensional accuracy are priorities. It is installed by CNC machinists and tool and die professionals in job shop, production, and maintenance machining environments. The positive side clearance and screw-holding method ensure secure, repeatable seating in compatible TPMT-style toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC820P carbide grade with CVD Al2O3 coating for high wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry optimized for finishing and light machining applications\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (8 degrees) and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape (TPMT) provides three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius supports fine surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method for secure, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPMT-style screw-clamping toolholders compatible with the TPMT21.52 ANSI insert size and TPMT110208 ISO insert size.

Use the manufacturer-recommended torque driver or screw key to seat the insert screw — do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the toolholder pocket for chips or damage before seating a new insert, and verify insert orientation relative to the cutting direction before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPMT21.52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPMT110208\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Full Code\u003c\/strong\u003e: TPMT110208N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\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: Al2O3 (CVD Process)\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 Style\u003c\/strong\u003e: TPMT\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 and 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: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\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 (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.107 inches\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 (P), Cast Iron (K)\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  \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: 19RJWC2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727315271986,"sku":"19RJWC2","price":156.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcfad14f8ee29515780e69828353e715.jpg?v=1788676213","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rjwc2-turning-insert-tpmt21-52esu-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
