Kennametal 2979111 Cutoff Insert KC5025 Carbide 2.05mm

Product Description

The KENNAMETAL 2979111 is a carbide cutoff insert engineered for parting and grooving operations on CNC lathes and turning centers. 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.

This 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.

Key Features

• 2.05 mm (0.0807 inch) cutting width for precise parting operations
• KC5025 carbide grade with TiAlN PVD coating for wear and heat resistance
• CF chipbreaker geometry promotes controlled chip formation and evacuation
• Neutral lead angle (0 degrees) for balanced radial cutting forces
• 2-degree relief angle reduces rubbing on the part-off face
• Clamp-style holding method ensures secure seating in compatible A4-series holders

Compatibility

Designed for use with A4-series clamp-style cutoff toolholders that accept insert seat size 2. Confirm holder series and insert seat size against the toolholder manufacturer specifications before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with turning center tooling setups. Power down and lock out the machine spindle before seating or removing inserts. Ensure the clamping mechanism is fully engaged and the insert is fully seated in the pocket before resuming cuts. Do not exceed the toolholder manufacturer recommended depth-of-cut or feed rate for this insert size.
