Designated CCMT431LF in the ISO\/ANSI insert identification system, it carries a PVD-applied TiAlN coating under the KC5010 manufacturer grade. This coating provides thermal resistance and wear performance suited to demanding cutting conditions. The insert features a neutral hand orientation, a positive rake angle of 5 degrees, a 7-degree relief angle, and an LF chip breaker geometry. The cutting edge is honed for edge stability. With 2 cutting edges per insert, it delivers consistent performance across multiple setups. Licensed machinists, CNC operators, and toolroom technicians specify this insert for turning, facing, and boring operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. The LF chip breaker geometry is engineered for finishing and light-to-medium roughing passes where controlled chip formation is critical. Its screw-on holding method suits standard CCMT-style toolholders commonly found in production turning environments, both in job shops and high-volume manufacturing cells. The insert is rated for a maximum depth of cut of 1.25 mm (0.0492 inches), making it best suited for finishing passes and light stock removal on the workpiece materials listed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 grade with PVD TiAlN coating for wear resistance on steel and superalloys\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light-to-medium turning passes\u003c\/li\u003e\n\u003cli\u003ePositive rake, honed cutting edge for reduced cutting forces and edge chipping\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard CCMT screw-on toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, and boring from a single insert style\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard screw-on CCMT-style toolholders conforming to ANSI and ISO standards for CCMT431 inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer specification — do not overtighten, as carbide inserts are brittle and susceptible to fracture under uneven clamping loads. Inspect the insert pocket and seating surface for chips or debris before installation to ensure accurate edge positioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT431LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees included angle)\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 (5 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (5.50 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: 0.0212 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: 1870987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749600035122,"sku":"1870987","price":237.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2435ce53b8e933b74dffe3732b37227.jpg?v=1788908171","url":"https:\/\/voomisupply.com\/products\/kennametal-1870987-ccmt431lf-kc5010-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
