Kennametal 1866569 CCGT325X0LF KC5025 Carbide Turning Insert

Product Description

The KENNAMETAL 1866569 is a solid carbide turning insert carrying the industry standard designation CCGT325X0LF in the KC5025 grade. It features a TiAlN coating applied via PVD process, delivering moderate wear resistance and toughness across a broad range of workpiece materials. The 80-degree diamond (rhombic) shape with a positive rake angle and positive side clearance geometry produces clean, controlled cuts at light depths. The LF chip breaker is optimized for finishing and light machining operations. The insert mounts via screw-on holding method and presents two usable cutting edges per insert, making it a cost-effective choice for precision turning applications in production and job-shop environments.

This insert is intended for CNC and manual lathes performing turning, facing, and boring operations. It is primarily suited to stainless steel and superalloys, with the KC5025 grade also rated for steel, cast iron, aluminum, and non-ferrous materials. The 80-degree included angle and honed cutting edge style reduce edge chipping and improve surface finish on difficult-to-machine materials. Licensed machinists and CNC operators working in aerospace, medical, and general manufacturing will find this insert well suited to tight-tolerance finishing passes where chip control and surface integrity are critical.

Key Features

• KC5025 grade with PVD TiAlN coating for moderate wear resistance and toughness
• LF chip breaker geometry engineered for finishing and light machining
• 80-degree diamond insert shape with positive rake and positive side clearance
• Two cutting edges per insert for extended tool life value
• Screw-on mounting method for secure, repeatable seating in compatible toolholders
• Rated for turning, facing, and boring in a single insert

Compatibility

Designed for use in screw-on style CCGT-format toolholders conforming to ANSI and ISO standards. ANSI insert code is CCGT325X0 and ISO insert code is CCGT09T3X0. Verify toolholder pocket geometry and screw-on compatibility before installation.

Installation Notes

This insert is installed by a qualified machinist or CNC technician. Power down and lock out the machine before changing inserts. Use the correct torque wrench and manufacturer-specified insert screw to seat the insert properly in the pocket — do not overtighten by hand estimation. Inspect the toolholder pocket for wear or debris before seating a new insert to avoid seating errors that affect tool runout and surface finish.
