Designed for external turning operations, this insert features an 80-degree diamond shape with a neutral hand orientation and a positive rake angle of 5 degrees. The KC5010 grade is engineered for high-speed, high-productivity cutting where edge toughness and thermal resistance are critical. The insert measures 5.65 mm in length, carries a 7\/32-inch inscribed circle, and a 1\/64-inch corner radius. The LF chipbreaker geometry promotes consistent chip control across a range of feed rates. Licensed machinists and CNC turning specialists are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning applications on steel, stainless steel, superalloys, and titanium. It performs well in ISO P, M, and S workpiece material categories, and is also applicable to secondary material codes N, P, and S. The screw-on holding method is compatible with standard CPMT-style toolholders. Typical use cases include finish and semi-finish turning on CNC lathes and turning centers where consistent surface finish and dimensional accuracy are required. Maximum depth of cut is 1.25 mm (0.0492 inches).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coating via PVD process for high thermal resistance and extended tool life in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eKC5010 carbide grade rated for steel, stainless steel, superalloys, and titanium (ISO P, M, S)\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides strong cutting edge geometry for profiling and facing\u003c\/li\u003e\n  \u003cli\u003eLF chipbreaker controls chip formation across varied feed and depth-of-cut conditions\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (5 degrees) reduces cutting forces and heat generation at the workpiece interface\u003c\/li\u003e\n  \u003cli\u003eScrew-on mount with 2 usable cutting edges for efficient insert utilization\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CPMT-style screw-on toolholders.

Ensure the machine spindle is fully stopped and all energy sources are locked out before indexing or replacing inserts. Use the correct torque wrench and screw type specified by the toolholder manufacturer to seat the insert securely without over-tightening. Inspect the insert pocket and clamping screw for wear 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 Style\u003c\/strong\u003e: CPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 18151\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-degree Diamond\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: KC5010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\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: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.65 mm (0.2224 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1043 inches (2.65 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Material Code\u003c\/strong\u003e: P, M, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Material Code\u003c\/strong\u003e: N, P, S\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: 0.022 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: 1854201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749690343730,"sku":"1854201","price":167.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a4ccd57fa6a1eb9b2e769c854437748.jpg?v=1788909250","url":"https:\/\/voomisupply.com\/products\/kennametal-1854201-turning-insert-cpmt18151lf-kc5010","provider":"Voomi Supply","version":"1.0","type":"link"}
