Featuring a 55-degree diamond insert shape with a positive rake angle of 15 degrees and a 7-degree relief angle, this insert is engineered for efficient chip control and clean surface finishes. The AC530U grade substrate carries a dual-layer TiAlN and AlCrN coating applied via PVD process under Sumitomo's Super ZX proprietary designation. The EFC chip breaker geometry supports consistent chip evacuation across a range of cutting conditions. Licensed machinists and CNC operators install this insert in compatible screw-lock toolholders for finish and semi-finish turning operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finish turning of stainless steel (ISO material group M) and other demanding workpiece materials in both production and job-shop environments. The screw-holding method and DCGT geometry make it appropriate for internal and external turning passes where precise dimensional control is required. The neutral hand designation allows flexible toolholder orientation. The ISO code for this insert is DCGT11T304N-FC, and it conforms to ANSI and ISO 13399 standards, supporting integration with tool management and digital manufacturing systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC530U carbide grade with TiAlN and AlCrN PVD dual-layer coating (Super ZX)\u003c\/li\u003e\n\u003cli\u003eEFC chip breaker geometry for controlled chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with positive 15-degree rake angle\u003c\/li\u003e\n\u003cli\u003e1\/64 inch corner radius for tight-tolerance finish turning\u003c\/li\u003e\n\u003cli\u003eScrew-lock holding method with 0.1732 inch hole diameter for secure seating\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code DCGT11T304N-FC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DCGT-style screw-lock turning insert compatible with DC-series toolholders accepting a 3\/8 inch inscribed circle, 55-degree diamond insert with a G tolerance and C clearance code per ANSI and ISO 13399 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert screw per the toolholder manufacturer's specification to seat the insert securely without over-torquing. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC530U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and AlCrN (Super ZX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EFC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 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\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\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\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Group M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCGT11T304N-FC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC\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: 1NHM933\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51728752705842,"sku":"1NHM933","price":216.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/329cf6e994832506087c6d8eab6adac1.jpg?v=1788695835","url":"https:\/\/voomisupply.com\/products\/sumitomo-1nhm933-carbide-turning-insert-55-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
