It belongs to the A2 insert series and carries the KC5025 manufacturer grade, a PVD-applied TiAlN coating engineered for wear resistance in steel and cast iron cutting applications. The insert delivers a 2.2 mm (0.0866 inch) cutting width and a 4.77 mm (0.1878 inch) cutting height. A 10-degree left-hand lead angle and a 2-degree relief angle are built into the geometry, and the CF chipbreaker configuration promotes controlled chip evacuation during deep cutoff passes. Toolroom machinists and CNC operators working in production turning environments install this insert using a clamp-style holding method.\u003c\/p\u003e\u003cp\u003eThis insert fits grooving and cutoff toolholders compatible with the A2 insert series and size code 022 seat. It is suited for left-hand lead angle configurations in applications where the tool approaches the workpiece from the left. Typical use cases include parting-off bar stock, shallow grooving, and finish-groove operations on ferrous and non-ferrous materials. The KC5025 grade with TiAlN PVD coating performs well in moderate to high cutting speed ranges on steel and similar materials. Each package contains one insert; the minimum order quantity is 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD-applied TiAlN coating for extended tool life in steel cutting\u003c\/li\u003e\n\u003cli\u003e2.2 mm cutting width (0.0866 inch) provides precise groove and cutoff dimensions\u003c\/li\u003e\n\u003cli\u003e10-degree left-hand lead angle with 2-degree relief angle for controlled engagement\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry supports chip control in continuous cutoff passes\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eA2 series, insert seat size 2 for straightforward toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in A2-series clamp-style cutoff and grooving toolholders that accept insert seat size 2 with a left-hand lead angle configuration.

Power down and lock out the machine spindle before changing inserts. Use the correct torque on the clamping screw as specified by the toolholder manufacturer documentation — do not over-tighten or use impact tools on the clamp screw. Inspect the insert seat and clamping components for wear or debris before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 022\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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: CF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.2 mm (0.0866 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.77 mm (0.1878 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0441 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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\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: 1790189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729512857906,"sku":"1790189","price":194.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dd2482ac9d0b852b7b182ed72de6d29.jpg?v=1788705488","url":"https:\/\/voomisupply.com\/products\/kennametal-1790189-carbide-cutoff-insert-kc5025-2-2mm","provider":"Voomi Supply","version":"1.0","type":"link"}
