Coated with titanium nitride (TiN) via a PVD process, this insert carries a BNC300 grade designation and conforms to ANSI insert code DNGA432 and ISO insert code DNGA150408. The 55-degree diamond (rhombic) shape provides a sharp, durable cutting geometry suited to high-hardness applications. With four cutting edges and a negative side clearance, the insert delivers consistent tool life in demanding finish-turning operations. It is installed by machinists and CNC tooling technicians working on hardened ferrous components.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning hardened steel workpieces, classified under ISO material code H. It fits standard DNGA-style toolholders that accept a 1\/2-inch inscribed circle insert with clamp and pin holding. Typical applications include finish and semi-finish turning of through-hardened or case-hardened components such as bearing races, shafts, and tooling steel parts. The ANSI size code is 432 and the ISO size code is 150408, which are the standard references used when cross-referencing compatible toolholder bodies and insert pockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material with TiN PVD coating for extended tool life on hardened steel\u003c\/li\u003e\n  \u003cli\u003eBNC300 manufacturer grade optimized for ISO material group H workpieces\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond (rhombic) insert shape  -  ANSI style DNGA, insert shape code D\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges with negative side clearance for rigid, stable clamping\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius (0.0313 inches) for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 DNGA-style toolholders accepting a 1\/2-inch inscribed circle insert with clamp and pin holding.

Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and seating surfaces are clean and free of debris before clamping to maintain accurate positioning. PCBN inserts are brittle  -  avoid impact or prying against the cutting edge during handling or installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: BNC300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGA150408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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: 0.0827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 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: 0.0150 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\u003eSide Clearance\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Steel (ISO Code H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: D\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\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: 16GBCHE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51739706655026,"sku":"16GBCHE","price":191.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6707f178e90c4907b9c5f7e45988b9d0_44927864-c466-4be9-a4c1-b36e8f5cd4a1.jpg?v=1788818061","url":"https:\/\/voomisupply.com\/products\/sumitomo-16gbche-turning-insert-dnga432-bnc300-pcbn","provider":"Voomi Supply","version":"1.0","type":"link"}
