Manufactured to ANSI code 3NUTPGA222 and ISO code 3NU-TPGW110308, this uncoated insert features a neutral hand orientation, a positive rake geometry, and a 1\/4-inch inscribed circle. The 60-degree included angle and 1\/32-inch corner radius make it well-suited for precision material removal on hardened and abrasive workpiece materials. It is held in place by a screw-lock clamping system and belongs to the TPG series.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning applications involving cast iron, hardened steel, and superalloys. The PCBN substrate provides the hardness and thermal stability needed to maintain cutting-edge integrity at elevated temperatures typical of hard turning and interrupted cuts in production environments. It is used in CNC turning centers and manual lathes by machinists and tooling technicians working in aerospace, automotive, and heavy manufacturing. The maximum depth of cut is 0.0150 inches, making it appropriate for finish and semi-finish turning passes rather than heavy stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolycrystalline Cubic Boron Nitride (PCBN) substrate for hard-turning and superalloy applications\u003c\/li\u003e\n\u003cli\u003eUncoated grade BN700 for consistent edge sharpness without coating buildup\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and heat generation at the tool-workpiece interface\u003c\/li\u003e\n\u003cli\u003e3 usable cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding method provides secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for interchangeability and documentation compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-lock TPG-style toolholders accepting a triangular insert with a 1\/4-inch inscribed circle and 11-degree relief angle.

Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Use the appropriate torque driver for the screw-lock fastener per the toolholder manufacturer guidelines — do not overtighten. Confirm insert index position and tool offset before returning the machine to operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 3NUTPGA222\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 3NU-TPGW110308\u003c\/li\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: BN700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0866 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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\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 Style\u003c\/strong\u003e: 3NU-TPGA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1300 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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hardened Steel, Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TPG\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: 0.04 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: 16FSW3J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51730232344882,"sku":"16FSW3J","price":139.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e89a6e5269b479dee106dfe5a9e389b.jpg?v=1788713785","url":"https:\/\/voomisupply.com\/products\/sumitomo-16fsw3j-pcbn-turning-insert-1-4-in-ic-tpg","provider":"Voomi Supply","version":"1.0","type":"link"}
