Kennametal 1790199 Cutoff Insert KC5025 Carbide 3 Mm

Product Description

The KENNAMETAL 1790199 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to A2 series geometry with a KC5025 manufacturer grade, this insert features a PVD-applied TiAlN coating for extended tool life in demanding cut-off applications. The 3.00 mm cutting width (0.1181 inch) and 4.68 mm cutting height (0.1843 inch) suit precision parting work where consistent chip control and edge integrity are critical. A CF chipbreaker geometry promotes reliable chip evacuation. Licensed machinists and toolroom technicians handling production turning work are the primary users of this insert.

This insert is suited for cut-off and grooving operations on bar stock and turned components in both production and job-shop environments. The right-hand lead angle of 10 degrees directs cutting forces appropriately for standard right-hand toolholding setups. The A2 series designation and insert seat size of 3 align this insert with compatible A2-style clamping toolholders used on manual and CNC turning equipment. The KC5025 grade is formulated for steel and cast iron applications where wear resistance and edge toughness are both required.

• A2 series insert style with clamp-held retention method for rigid setup
• Relief angle of 2.00 degrees supports clearance in tight parting grooves
• Insert seat size 3 aligns with A2-compatible toolholder systems

Compatibility

Designed as an OEM-style replacement insert for A2 series clamping toolholders accepting insert seat size 3 with a 3.00 mm cutting width.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and seating procedures. Ensure the machine spindle is fully stopped and the turret is in a safe position before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not use damaged or improperly seated inserts, as this creates a risk of insert fracture during cutting.
