It features a 60-degree triangular shape with a positive rake geometry and an 11-degree relief angle, delivering clean, consistent chip formation in finishing and semi-finishing applications. The T1500Z cermet grade with PVD coating provides wear resistance and edge integrity at elevated cutting speeds. This insert is held in place by a screw-clamp method and is intended for installation by machining professionals and CNC lathe operators working to tight tolerances.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel components in both production and job-shop environments. The left-hand orientation and LW chip breaker make it appropriate for specific toolholder configurations requiring directional cutting geometry. With a 3\/16 inch inscribed circle and a 1\/64 inch corner radius, it is sized for light-depth finishing passes where surface finish and dimensional accuracy are the priority. It meets ANSI and ISO 13399 standards, with an ANSI code of TPGT631L and ISO code TPGT080204L-W.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eT1500Z cermet grade with PVD coating for extended tool life on steel\u003c\/li\u003e\n\u003cli\u003ePositive rake, 11-degree relief angle reduces cutting forces on finishing passes\u003c\/li\u003e\n\u003cli\u003eLW chip breaker geometry promotes controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert hand for compatible directional toolholders\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 standards for insert identification and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TPGT-style screw-clamp toolholders configured for left-hand, positive-rake triangular inserts with a 3\/16 inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified method without overtightening, which can fracture the insert. Handle cermet inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TPGT631L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPGT080204L-W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T1500Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3228 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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\u003eSeries\u003c\/strong\u003e: TP\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: 0.19 inches H x 0.19 inches W x 0.09 inches L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 104A792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51749722390834,"sku":"104A792","price":201.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_8ad9acf9-f26b-4e7f-91f6-f0c915137668.jpg?v=1788909579","url":"https:\/\/voomisupply.com\/products\/sumitomo-104a792-cermet-turning-insert-tpgt631l","provider":"Voomi Supply","version":"1.0","type":"link"}
