Manufactured from K68 grade uncoated carbide, this insert offers high wear resistance with moderate toughness, making it well-suited for finishing and semi-finishing operations on stainless steel, cast iron, aluminum, and other non-ferrous materials. The triangular insert shape provides three usable cutting edges, and the screw-on holding method ensures secure, repeatable positioning in compatible toolholders. Corner radius measures 0.0156 inches (1\/64 inch), and the inscribed circle diameter is 0.375 inches (3\/8 inch).\u003c\/p\u003e\u003cp\u003eThis insert is applied in turning operations across a range of workpiece materials coded P, M, K, N, and S per ISO classification. It is primarily suited for light to moderate depth-of-cut passes, with a maximum depth of cut of 0.0492 inches (1.25 mm). Typical install scenarios include CNC lathe toolholder setups in job shop, production machining, and maintenance machining environments. Machinists and CNC operators handling stainless steel and cast iron components will find this insert well-matched for high wear-resistance applications requiring a positive rake and positive side clearance geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eK68 uncoated solid carbide grade delivers high wear resistance for stainless steel (M), cast iron (K), and aluminum and non-ferrous (N) workpiece materials\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (T) provides three usable cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003ePositive rake and positive side clearance geometry reduces cutting forces for cleaner finishes\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method ensures rigid, repeatable seating in compatible TP-style toolholders\u003c\/li\u003e\n\u003cli\u003eNo chip breaker design supports smooth, consistent chip flow in finishing and light semi-finishing cuts\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports use in both left- and right-hand turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with screw-on TP-style turning toolholders accepting a 3\/8 inch inscribed circle triangular insert.

Always power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to secure the screw-on clamp to the manufacturer-specified holding torque for the toolholder in use. Inspect the insert pocket and seating surface for chips or debris before seating the insert to ensure accurate positioning and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TP61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TP160304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCGT431HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches (16.50 mm)\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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\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\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.291 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1163039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728705716530,"sku":"1163039","price":180.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/823eb177c352b4b9f94ec0e8df3482b1.jpg?v=1788695289","url":"https:\/\/voomisupply.com\/products\/kennametal-1163039-turning-insert-k68-carbide-3-8-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
