Manufactured to ANSI insert code TPGH321 and ISO code TPGH160304, this uncoated carbide insert features a 60-degree triangular shape with a positive side clearance and an 11-degree relief angle. The inscribed circle measures 3\/8 inches (0.3750 inches) and the corner radius is 1\/64 inches (0.0156 inches). Grade I22 carbide with a bright, uncoated finish provides a sharp cutting edge suited for finishing and semi-finishing passes where coating adhesion or heat are less critical. Licensed machinists and CNC operators are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning applications involving non-ferrous metals, cast iron, stainless steel, and high-temperature alloys, corresponding to primary workpiece material codes K, M, N, and S. The TPGH style with a screw-holding method provides secure seating in compatible toolholders during both light and moderate interrupted cuts. The H chip breaker geometry helps control chip flow during finishing operations. Typical applications include OD turning, facing, and light profiling on production or job-shop lathes where dimensional accuracy and surface finish are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide grade I22 with bright uncoated finish for sharp, consistent cutting edges\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape (T) with positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle provides clearance and reduces flank wear on finishing passes\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch (0.0156 inch) corner radius suited for fine-finish turning applications\u003c\/li\u003e\n  \u003cli\u003eH chip breaker geometry for effective chip control in finishing and semi-finishing\u003c\/li\u003e\n  \u003cli\u003eScrew-held (clearance code P, tolerance code G) for rigid, repeatable toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit standard TPGH-style screw-clamp toolholders accepting a 321 ANSI size code insert with a 0.1770-inch hole diameter.

Ensure the machine spindle is fully stopped and all motion is locked out before changing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to seat the clamping screw; do not over-torque the insert screw, as carbide is brittle and may fracture. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and dimensional repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPGH321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPGH160304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle, 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: I22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, N, S\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\u003eANSI Size Code\u003c\/strong\u003e: 321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 160304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0005 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ICC21020L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698565054770,"sku":"ICC21020L","price":232.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87bdb14293dad7112523453df37fd484.jpg?v=1788364769","url":"https:\/\/voomisupply.com\/products\/value-collection-icc21020l-turning-insert-tpgh321-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
