It carries an 80-degree diamond (rhombic) shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a corner radius of 3\/64 inch (0.0469 inch). The insert seats via clamp or pin holding in KENLOC-style toolholders and delivers moderate wear-resistance and toughness across a broad range of workpiece materials. Four cutting edges per insert extend tool-life value. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations. Its KCU25 grade targets steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and superalloys including titanium, making it suited for both roughing and medium machining passes. The MS chip breaker geometry manages chip formation across variable feed and depth-of-cut conditions. It conforms to ANSI insert code CNMG433 and ISO insert code CNMG120412, fitting toolholders dimensioned to those standards. The maximum depth of cut is 0.1691 inch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 PVD AlTiN coating provides moderate wear-resistance and toughness for steel, stainless steel, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake and negative side clearance for rigid, stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003eMS chip breaker supports roughing and medium machining operations with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert reduce per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces microchipping at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods; meets ANSI and ISO dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for KENLOC-series toolholders accepting CNMG433 (ANSI) or CNMG120412 (ISO) inserts with clamp or pin holding.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamp hardware to seat the insert; do not over-torque the clamping screw. Inspect the insert pocket and seating surface for chips or debris before installing a fresh edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG433\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG433MS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\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: AlTiN (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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: MS (Roughing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 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: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees negative\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 and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium, Cast Iron, Aluminum and Non-Ferrous\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: 0.02 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: 4050455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731811664178,"sku":"4050455","price":182.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5afa670f761fb6868af57d9668581712.jpg?v=1788735192","url":"https:\/\/voomisupply.com\/products\/kennametal-4050455-cnmg433ms-turning-insert-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
