It is designed for precision turning operations on hardened ferrous materials, cast irons, and superalloys in CNC lathe and turning center applications. The insert features an 80-degree diamond shape (ANSI shape code C), a negative rake geometry, and four usable cutting edges per insert. With a 1\/2-inch inscribed circle and a 3\/16-inch insert thickness, this insert fits standard CNGA-style toolholders. Machinists and CNC operators in production and job shop environments typically install and qualify this insert.\u003c\/p\u003e\u003cp\u003eThe 16DTCEA is suited for finishing and light semi-finishing passes on hardened steels, chilled cast iron, and hard-turning applications where CBN tooling replaces grinding. The 4NC-CNGA insert style and ISO code 4NC-CNGA120404 indicate compatibility with CNGA-format toolholders common in production turning cells. The BNC200 manufacturer grade is formulated for interrupted and continuous cuts on secondary workpiece material group H. A chip breaker style A is incorporated into the geometry to assist with chip control during hard-turning passes where maximum depth of cut is limited to 0.015 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material with PVD-applied titanium nitride coating for extended tool life on hardened workpieces\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with negative rake for stable, rigid cutting geometry\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for cost-effective tooling rotation\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.015 inches suited for finishing and close-tolerance hard-turning\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius for controlled surface finish on finish-turning passes\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 standards for insert identification and toolholder interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGA-style turning toolholders with clamp and pin holding methods. The ISO designation 4NC-CNGA120404 and ANSI insert style 4NC-CNGA confirm fitment in standard CNGA-format holders used on CNC lathes and turning centers.

Power down and lock out the machine spindle before changing inserts. Use the correct torque on the clamp screw per the toolholder manufacturer specification — do not over-torque. Inspect the toolholder seat and pin for wear or debris before seating a fresh insert, as contamination at the pocket face will affect insert stability and surface finish results.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BNC200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Shape Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 4NC-CNGA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 4NC-CNGA120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0984 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\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: C\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: 0.025 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: 16DTCEA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51749460476210,"sku":"16DTCEA","price":174.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f47aff84ae7126c45c765ab6fb8798b6_ce94b83a-b00d-4bab-911b-a6a3bf6805d6.jpg?v=1788906377","url":"https:\/\/voomisupply.com\/products\/sumitomo-16dtcea-pcbn-turning-insert-80-diamond-bnc200","provider":"Voomi Supply","version":"1.0","type":"link"}
