Kennametal 4045241 DCGT32505HP KCU10 Turning Insert

Product Description

The KENNAMETAL 4045241 is a solid carbide turning insert with a DCGT32505HP geometry and KCU10 grade, designed for precision finishing operations on CNC lathes and turning centers. The insert features a TiAlN coating applied via PVD process, delivering high wear resistance across a range of workpiece materials. It carries a 55-degree diamond (rhombic) shape with a positive rake angle of 15 degrees and a 7-degree relief angle. The 0.0079-inch corner radius and honed cutting edge style make this insert well suited for tight-tolerance finishing passes where surface finish and dimensional accuracy are critical. Licensed machinists and CNC operators are the primary installers.

This insert is intended for turning, facing, boring, back turning, and back boring applications. It is rated for use on steel, stainless steel, superalloys, titanium, cast iron, and aluminum, covering ISO material codes P, M, K, N, S, and H. The KCU10 grade provides high to moderate wear resistance and toughness across these material groups. The screw-on holding method and neutral hand orientation allow flexible use in standard DCGT-style toolholders. Typical applications include finishing passes in both high-volume production and precision job shop environments.

Key Features

• TiAlN coating via PVD process for high wear resistance and thermal stability
• 55-degree diamond insert shape with positive rake for reduced cutting forces during finishing
• Honed cutting edge style optimized for tight-tolerance finishing operations
• Compatible with screw-on toolholding systems; neutral hand for versatile setup
• 2 cutting edges per insert for extended service life
• Rated for multiple material groups: steel, stainless steel, cast iron, superalloys, titanium, and aluminum

Compatibility

Designed as a screw-on replacement insert for DCGT-style toolholders conforming to ANSI insert code DCGT32505 and ISO insert code DCGT11T302HP. Verify toolholder pocket geometry and screw size before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified seating practice — do not overtighten. Inspect the insert seat and chip groove for debris before seating the new insert to ensure proper contact and runout accuracy.
