It features a triangular (60-degree) insert shape with a positive rake angle and positive side clearance, providing free-cutting action and reduced cutting forces. The insert has a 3\/8 inch inscribed circle, a 1\/32 inch corner radius, and a flat-top chip breaker geometry. With an ANSI insert code of TPG322 and ISO code TPG160308, it conforms to recognized industry standards for interchangeability and toolholder compatibility. Grade K68 delivers high wear resistance combined with moderate toughness, making it well suited for demanding applications on non-ferrous metals, stainless steel, cast iron, and superalloys.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in KENDEX-style toolholders on CNC lathes and manual turning centers in production and job-shop environments. Its multi-use designation covers turning, facing, and boring applications. Licensed machinists and CNC operators working with non-ferrous metals, stainless steel, cast iron, aluminum, and superalloys including titanium will find the K68 grade appropriate for high wear-resistance to moderate wear-resistance and toughness requirements. The flat-top chip breaker and honed cutting edge contribute to consistent chip control and surface finish across the three available cutting edges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade K68 solid carbide, uncoated (bright finish) for high wear resistance and moderate toughness\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape with 60-degree included angle and three usable cutting edges\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance reduce cutting forces on challenging workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker with honed cutting edge for consistent chip control\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm) per pass\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards for toolholder interchangeability\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method for rigid, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENDEX-series clamp-style toolholders accepting TPG322 or TPG160308 inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert — do not overtighten the clamp screw by hand estimation. Inspect the insert seat and clamp for chips or debris before seating a new edge to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPG322\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPG160308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 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: K68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6495 inches (16.50 mm)\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\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0086 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1183258\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732360823090,"sku":"1183258","price":145.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e2147113d2f65a1c1c9af0a1bd42b89.jpg?v=1788742069","url":"https:\/\/voomisupply.com\/products\/kennametal-1183258-tpg322-k68-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
