Kennametal 4111098 Carbide Cutoff Insert 3mm Neutral A2

Product Description

The KENNAMETAL 4111098 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the KCU25 manufacturer grade with an AlTiN coating applied via PVD process, delivering strong wear resistance and thermal stability in interrupted and continuous cuts. The cutting width is 3.00 mm (0.1180 inches) with a neutral lead angle and a 2-degree relief angle. A CM chipbreaker geometry controls chip flow in medium-duty cutoff applications. Machinists and tooling technicians working in production turning environments rely on this insert for repeatable part-off performance on steel, cast iron, and similar workpiece materials.

This insert is suited for parting-off and grooving operations in medium to high production turning environments, both in job shops and larger manufacturing facilities. Its Series A2 designation matches it to compatible A2-style cutoff toolholders. The neutral hand orientation makes it adaptable to both left- and right-hand tooling setups. The CM chipbreaker is well matched to moderate feed rates and depths common in general-purpose parting work. Installation requires a qualified A2-series toolholder; confirm seat and clamping compatibility before use.

Key Features

• KCU25 grade carbide with AlTiN coating via PVD process for wear and heat resistance
• 3.00 mm (0.1180 inch) cutting width for precise parting and grooving
• Neutral lead angle and neutral hand for flexible toolholder orientation
• CM chipbreaker geometry for controlled chip evacuation at moderate feeds
• 2-degree relief angle reduces rubbing on the cut face
• Single-end insert design for consistent edge indexing

Compatibility

Designed for use with A2-series cutoff and grooving toolholders that accept the A2030N00CM02 insert style. Confirm toolholder seat dimensions and clamping screw compatibility before installation.

Installation Notes

This insert is installed and serviced by machinists and CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing the insert. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer; do not overtighten the clamp screw by feel alone. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and alignment.
