The insert features a Physical Vapor Deposition (PVD) Titanium Nitride (TiN) coating for enhanced surface hardness and wear resistance. With a 1\/2 inch inscribed circle, 0.0945 inch insert length, and a 1\/32 inch corner radius, this insert is engineered for tight tolerances on CNC turning centers. It is installed by machinists and toolroom professionals operating high-speed, high-precision lathes.\u003c\/p\u003e\n\u003cp\u003eThe 16HUBXB is suited for finish and semi-finish turning of hardened steels and secondary workpiece materials classified as H-group (hardened steels). It belongs to the Series C insert family with an 80-degree diamond (rhombic) insert shape, providing two highly stable cutting points per face. With four total cutting edges, this insert delivers extended tool life per unit and is appropriate for both production environments and tight-tolerance job shop work where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material with PVD Titanium Nitride coating for elevated wear resistance in hardened steel turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake geometry for strong, stable cutting edge\u003c\/li\u003e\n  \u003cli\u003eWiper edge geometry (Chip Breaker A) promotes improved surface finish at standard feed rates\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum value in high-volume turning operations\u003c\/li\u003e\n  \u003cli\u003e1\/32 inch corner radius and 0.0150 inch maximum depth of cut suited for finish turning passes\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method compatible with standard CNGA-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards; ISO code 4NC-CNGA120408W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit insert for CNGA-style toolholders accepting 1\/2 inch inscribed circle, 3\/16 inch thick, 80-degree diamond inserts.

Power down and lock out the machine spindle before seating or indexing any insert. Use the appropriate torque wrench per the toolholder manufacturer specifications when tightening the clamping screw  -  do not over-torque. Inspect the insert pocket for damage, chips, or contamination before seating the new insert, as debris under the insert seat will cause premature edge failure or dimensional error.\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: BNC160\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-CNGA120408W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 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 Length\u003c\/strong\u003e: 0.0945 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\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\u003eCoating\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\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\u003eWiper Edge\u003c\/strong\u003e: Yes\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\u003c\/strong\u003e: Steel (H-group)\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 16HUBXB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51740324233522,"sku":"16HUBXB","price":190.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cef794df6686299a8097a0521dc02b41.jpg?v=1788824315","url":"https:\/\/voomisupply.com\/products\/sumitomo-16hubxb-pcbn-turning-insert-1-2-in-ic-bnc160","provider":"Voomi Supply","version":"1.0","type":"link"}
