It carries the AC820P manufacturer grade with a CVD-applied aluminum oxide (Al2O3) coating, which provides thermal resistance and wear protection during continuous and interrupted cuts. The insert has a triangular shape with a 60-degree included angle, a neutral hand orientation, and a 7-degree relief angle. With a 1\/4-inch inscribed circle and a 1\/64-inch corner radius, this insert suits finishing and semi-finishing passes where edge integrity and surface finish consistency matter. It is held in place by a screw-type clamping system.\u003c\/p\u003e\u003cp\u003eThe 19RJBPR is intended for use in turning applications where steel is the primary workpiece material, consistent with its Secondary Workpiece Material Code P designation. The ESU chip breaker geometry promotes chip control during light to medium material removal on ferrous components. The positive rake angle of 8 degrees reduces cutting forces, making this insert well suited to applications requiring tight tolerances and smooth surface finishes. It conforms to ANSI code TCMT21.51ESU and ISO code TCMT110204N-SU, allowing straightforward cross-referencing with toolholder specifications that accept the TCMT insert family.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC820P grade with CVD Al2O3 coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eESU chip breaker geometry engineered for effective chip control on steel\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 8 degrees reduces cutting forces on finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation allows use in a range of turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TCMT-style screw-on toolholders that accept a triangular insert with a 1\/4-inch inscribed circle, 7-degree clearance angle (Clearance Code C), and Tolerance Code M per ANSI and ISO 13399 standards.

Use the correct torque wrench and manufacturer-specified clamp screw to seat the insert without cracking the carbide substrate. Inspect the toolholder pocket for chips or debris before seating a new insert, as contamination will affect insert indexing and surface finish results.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TCMT21.51ESU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT110204N-SU\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\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 (Aluminum Oxide)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESU\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: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 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: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 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\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\u003eSeries\u003c\/strong\u003e: TC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary 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\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\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: 19RJBPR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51755568431410,"sku":"19RJBPR","price":166.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/883e52897796079264c9cc0a2b7bea40.jpg?v=1788956191","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rjbpr-turning-insert-tcmt-triangle-ac820p","provider":"Voomi Supply","version":"1.0","type":"link"}
