Built to ANSI code 3NUTPGA221 and ISO code 3NU-TPGW110304, this insert features a triangular shape with a 60-degree included angle, providing three usable cutting edges per insert. The BN7000 manufacturer grade delivers the hardness and thermal stability required when cutting hardened steels, cast iron, and superalloys at elevated cutting speeds. Holding is via screw clamp, and the positive rake geometry helps reduce cutting forces and heat generation at the edge. Insert thickness is 0.125 inches and inscribed circle diameter is 0.25 inches.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finish and semi-finish turning applications in aerospace, automotive, and general machining environments where conventional carbide tooling reaches its limits. Primary workpiece materials include cast iron, hard materials, and superalloys, making it a go-to choice for shops running hardened components or high-temperature alloy parts. The neutral hand designation means it fits standard right- or left-hand toolholders configured for TPG-style inserts. It is installed by licensed machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN insert material provides extreme hardness for cutting cast iron, hard materials, and superalloys\u003c\/li\u003e\n\u003cli\u003eBN7000 grade with coated finish optimized for high-speed dry or near-dry turning\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (T) with 60-degree included angle yields three cutting edges per insert\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and edge temperature\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method (clearance code P, tolerance code G) for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for toolholder compatibility documentation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for toolholders accepting TPG-series, screw-clamp triangular inserts with a 1\/4-inch inscribed circle and 1\/8-inch thickness per ANSI 3NUTPGA221 and ISO 3NU-TPGW110304 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key to torque the clamp screw to the toolholder specification  -  do not overtighten, as PCBN inserts are brittle and can fracture under excessive clamping force. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.\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: BN7000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: 3NUTPGA221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 3NU-TPGW110304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.0984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material, Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 0.43 x 0.25 x 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 16JYDSY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51742800970034,"sku":"16JYDSY","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a1e7db482175fd6be6a5fe6a99753d2_bddce31b-490b-4013-9de8-955d410f26ef.jpg?v=1788839488","url":"https:\/\/voomisupply.com\/products\/sumitomo-16jydsy-pcbn-turning-insert-triangle-bn7000","provider":"Voomi Supply","version":"1.0","type":"link"}
