Manufactured to the K68 grade, this insert delivers high wear resistance with moderate toughness, making it well suited for interrupted and continuous cuts in stainless steel, cast iron, aluminum, and other non-ferrous materials. The triangular insert geometry (60-degree included angle) provides three usable cutting edges. With a neutral hand orientation and a screw-on holding method, it seats securely in compatible TP-style toolholders without additional clamping hardware.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in turning, facing, and light profiling operations across aerospace, general machining, and production shop environments. The positive rake and positive side clearance geometry reduce cutting forces, which helps control heat buildup and extends tool life when machining gummy or abrasive workpiece materials. The 0.03125-inch corner radius suits moderate finishing and semi-finishing passes. No chip breaker is present, so it is best applied where chip management is handled through feed, speed, and coolant selection rather than insert geometry alone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK68 solid carbide grade: high wear resistance to moderate toughness, rated for stainless steel (M), cast iron (K), aluminum and non-ferrous (N), and superalloys (S)\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape with 60-degree included angle provides three cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish maintains sharp edge geometry without coating buildup — preferred for non-ferrous and sticky alloys\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance reduce cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eScrew-on mounting method provides rigid, repeatable seating in TP-style toolholders\u003c\/li\u003e\n  \u003cli\u003eNo chip breaker design allows direct control of chip formation through cutting parameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on TP-style turning toolholders.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and tighten the mounting screw to the toolholder manufacturer's specification — do not over-torque the screw, as this can crack the carbide insert or damage the pocket. Inspect the insert pocket and screw threads for chips or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Triangle (T) — 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Length\u003c\/strong\u003e: 11 mm (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.03125 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\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TP42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TP1100208\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TCMT3252MF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 1100208\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 0.004 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1163038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737751421234,"sku":"1163038","price":175.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/282164abaa12d2ed544d890ba130c7a6.jpg?v=1788793154","url":"https:\/\/voomisupply.com\/products\/kennametal-1163038-turning-insert-tp42-k68-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
