Kennametal 1866565 Turning Insert CCGT2150LF KC5025

Product Description

The KENNAMETAL 1866565 is a solid carbide turning insert in the CCGT2150LF KC5025 style, designed for precision metal cutting in CNC turning, facing, and boring operations. The insert features a TiAlN coating applied via PVD process, an 80-degree diamond (rhombic) shape, and a positive rake geometry that reduces cutting forces during light finishing passes. With a 0.0039-inch corner radius and a 0.25-inch inscribed circle, this insert is built for fine finishing and light machining where surface finish and dimensional accuracy are critical. Grade KC5025 delivers moderate wear resistance and toughness across a broad range of workpiece materials.

This insert is suited for finishing and light machining of stainless steel, superalloys, titanium, steel, cast iron, aluminum, and other non-ferrous materials. It is used in applications where positive cutting geometry and a sharp honed edge are required to maintain close tolerances and minimize tool pressure. The screw-on holding method provides secure, repeatable seating in compatible CCGT-style toolholders used in production and job-shop turning environments.

Key Features

• TiAlN coating via PVD process for wear resistance across P, M, K, N, and S material classes
• 80-degree diamond (rhombic) insert shape for versatile turning, facing, and boring
• Positive rake angle reduces cutting forces during finishing and light machining passes
• LF chip breaker geometry optimized for finishing and light machining operations
• Honed cutting edge style for improved edge stability on difficult-to-machine alloys
• Screw-on mounting for secure, repeatable insert indexing with 2 usable cutting edges

Compatibility

Designed for use in CCGT-style screw-on toolholders accepting a 0.25-inch inscribed circle insert. Conforms to ANSI insert code CCGT21502 and ISO insert code CCGT060201. Compatible with multi-use turning, facing, and boring applications per ANSI and ISO standards.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the manufacturer-recommended torx or hex key to seat the screw-on fastener to proper engagement without over-torquing, which can crack the carbide. Inspect the toolholder pocket and seating surfaces for chips or debris before installing a new insert to ensure accurate, stable seating.
