Designated under the A4 series with style code A4C0205N00CF02, this insert features a 2.05 mm (0.0807 inch) cutting width and a neutral lead angle, making it well-suited for straight-on cutoff work where side forces must be minimized. The KC5025 grade combines a TiAlN PVD coating over a carbide substrate, providing thermal resistance and edge wear performance during interrupted or continuous cut-off passes. The CF chipbreaker geometry promotes controlled chip evacuation in tight parting-tool applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for metalworking professionals operating production turning equipment. It fits applications involving cutoff of ferrous and non-ferrous workpieces in both job-shop and production environments. The clamp-style insert holding method is compatible with A4-series cutoff toolholders. The 0-degree lead angle and neutral geometry suit applications where the part-off tool must approach the workpiece perpendicular to the spindle axis. Sold individually per package with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.05 mm (0.0807 inch) cutting width for precise parting operations\u003c\/li\u003e\n\u003cli\u003eKC5025 carbide grade with TiAlN PVD coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eCF chipbreaker geometry promotes controlled chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle (0 degrees) for balanced radial cutting forces\u003c\/li\u003e\n\u003cli\u003e2-degree relief angle reduces rubbing on the part-off face\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method ensures secure seating in compatible A4-series holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with A4-series clamp-style cutoff toolholders that accept insert seat size 2.
