Kennametal 1793809 Cutoff Insert KC5025 Carbide 4 Mm

Product Description

The KENNAMETAL 1793809 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the A2040R06CR03 designation within the Series A2 platform and is manufactured to grade KC5025 with a PVD-applied TiAlN coating. The insert delivers a 4.00 mm cutting width and a 4.66 mm cutting height, making it suited for moderate-depth cutoff work where edge wear resistance and dimensional consistency are critical. A clamp-style holding method secures the insert in the toolholder. The 6-degree right-hand lead angle and CR chipbreaker geometry promote controlled chip flow and reduce the risk of chip packing during deep parting cuts.

This insert is intended for production turning environments where carbide tooling is used on steel, cast iron, and similar workpiece materials falling within the C2 and C6 material grade range. Typical applications include OD grooving, parting to center, and face grooving on conventional or gang-tool lathe setups. The TiAlN coating extends tool life in dry or minimal-coolant cutting conditions. This insert is sold individually and must be ordered in multiples of 5 to meet minimum order requirements.

Key Features

• KC5025 carbide grade with PVD TiAlN coating for wear resistance in steel and cast iron
• 4.00 mm cutting width with 0.0118 inch corner radius for consistent groove geometry
• 6-degree right-hand lead angle with CR chipbreaker for controlled chip evacuation
• Clamp-style insert holding method compatible with Series A2 toolholders
• 2-degree relief angle reduces rubbing on groove walls during cutoff
• Insert seat size 4 for positive location and repeatable depth of cut

Compatibility

Designed for use with Series A2 clamp-style cutoff and grooving toolholders accepting insert seat size 4 at a 4.00 mm cutting width.

Installation Notes

Cutoff and grooving inserts are installed and replaced by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the turret is in a safe index position before handling inserts. Inspect the insert pocket and clamp for burrs or debris before seating the new insert, as contamination can affect clamping force and insert orientation. Follow the toolholder manufacturer torque guidance for the clamping screw and verify insert seating visually before resuming operation.
