Kennametal 4111097 Carbide Cutoff Insert 3 Mm A2 Series

Product Description

The KENNAMETAL 4111097 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries a KCU25 manufacturer grade with an AlTiN coating applied via PVD process, delivering wear resistance and thermal stability in interrupted and continuous cuts. The cutting width measures 3.00 mm (0.1180 inches) with a neutral lead angle and a 0-degree relief angle. A CF chipbreaker geometry controls chip flow in tight grooving applications. This insert is installed by machinists and toolroom professionals working with A2-series cutoff toolholders.

The 4111097 is suited for grooving, parting-off, and profile turning on ferrous and non-ferrous workpieces where consistent chip control and edge integrity are required. The A2 series designation matches standard A2-compatible insert pockets. The neutral hand orientation allows use in both right- and left-hand toolholder arrangements without repositioning. Typical applications include production turning on manual and CNC equipment in job shops, aerospace component machining, and general metalworking environments.

Key Features

• KCU25 carbide grade with AlTiN PVD coating for thermal and abrasion resistance
• 3.00 mm (0.1180 inch) cutting width for precise parting and grooving
• CF chipbreaker geometry for controlled chip evacuation in deep grooves
• Neutral lead angle and neutral hand for versatile toolholder compatibility
• Single-end insert design; A2 series profile for standard pocket fit
• Corner radius of 0.0080 inches for controlled edge geometry at groove walls

Compatibility

Designed for use with A2-series cutoff and grooving toolholders that accept inserts with a 3 mm cutting width and CF chipbreaker profile.

Installation Notes

Installation is performed by qualified machinists. Ensure the toolholder pocket is clean and free of chips or burrs before seating the insert. Power down and lock out the machine before changing inserts. Follow the toolholder manufacturer torque specifications for the clamping screw; do not overtighten, as carbide inserts are brittle and susceptible to fracture under clamp distortion.
