Carrying ANSI designation DCMT32.51ESU and ISO code DCMT11T304N-SU, this insert features a 55-degree diamond shape with a positive rake angle of 8 degrees and a 7-degree relief angle. The AC830P manufacturer grade with CVD-applied Al2O3 coating provides thermal resistance and wear performance suited for continuous and interrupted turning operations. The ESU chip breaker geometry promotes controlled chip flow across a range of cutting conditions. Installed by machinists and CNC tooling technicians, this insert mounts via screw-hold clamping in compatible DCMT-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for universal secondary workpiece material applications, covering a broad range of steel and general-purpose turning scenarios. With a neutral hand orientation, it functions in standard right-hand toolholder setups without directional limitation. The 3\/8-inch inscribed circle and compact 0.4567-inch insert length make it appropriate for finish and semi-finish turning passes where dimensional accuracy and surface finish consistency are priorities. The 1\/64-inch corner radius supports light-to-moderate depth-of-cut applications on a variety of ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P grade with CVD Al2O3 coating for elevated thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (Shape Code D) with 7-degree clearance angle\u003c\/li\u003e\n  \u003cli\u003eESU chip breaker geometry for controlled chip evacuation during turning\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (8 degrees) reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eScrew-hold clamping method (Tolerance Code M, Clearance Code C) for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards for tooling data interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DCMT-style screw-clamp turning toolholders compatible with the DCMT32.51 insert seat size.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the toolholder pocket before tightening the clamping screw to avoid insert rocking or improper seating. Inspect the insert seat and pocket for chips or debris prior to installation, as contamination can affect insert orientation and cutting accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DCMT32.51ESU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT11T304N-SU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees, Shape Code D)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\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\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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4567 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Universal (M, 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: 0.018 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: 19RBBPK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51731917472050,"sku":"19RBBPK","price":250.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49fc678e8a49434786a07b47fa108344.jpg?v=1788736578","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbbpk-turning-insert-dcmt32-51esu-ac830p","provider":"Voomi Supply","version":"1.0","type":"link"}
