Kennametal 4045329 TPGT2152LF KCU10 Carbide Turning Insert

Product Description

The KENNAMETAL 4045329 is a solid carbide turning insert in the TPGT style, grade KCU10, with a TiAlN coating applied via PVD process. It carries a 60-degree triangular shape with a positive rake angle of 5 degrees, a clearance code of P, and a tolerance code of G. The insert delivers three usable cutting edges and is designed for screw-on holding systems. With a 0.25-inch inscribed circle and a 0.03125-inch corner radius, it suits precision finishing and light-to-moderate material removal. Licensed machinists and CNC turning specialists install this insert in lathes, turning centers, and boring applications where tight tolerances on difficult materials are required.

This insert is rated for primary use on steel, stainless steel, superalloys, and titanium, corresponding to ISO workpiece material codes P, M, and S. Secondary suitability covers codes K and N. The LF chip breaker geometry supports low-feed finishing passes where surface finish and edge control matter. It is applicable for turning, facing, and boring operations, making it a versatile option for shops running mixed-material work on CNC or manual turning equipment.

Key Features

• KCU10 carbide grade with TiAlN PVD coating for wear resistance on steel, stainless, and titanium
• 60-degree triangle shape (TPGT) with positive 5-degree rake for reduced cutting forces
• LF chip breaker geometry optimized for finishing and low-feed operations
• Three cutting edges per insert for extended tool life and cost efficiency
• Screw-on holding method for secure, repeatable seating in standard TPGT toolholders
• Honed cutting edge style for consistent performance on difficult-to-machine alloys

Compatibility

Designed for use in screw-on TPGT-style toolholders. ISO designation TPGT110208LF. Suitable for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium. Meets ANSI and ISO standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the manufacturer-specified torque driver for the screw-on clamping system to avoid cracking the carbide substrate — do not overtighten by hand or with general-purpose tools. Inspect the toolholder pocket and seating surface for chips or debris before seating the new insert.
