Kennametal 5652239 X400 Square Milling Insert Tialn

Product Description

The KENNAMETAL 5652239 is a solid carbide milling insert in the X400 grade, designed for indexable milling operations on steel and hard materials. Carrying the ANSI/ISO designation XDLW090408SRD, this square-shaped insert measures 0.375 inches wide, 0.375 inches long, and 0.187 inches thick. It features a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cutting environments. The insert uses a screw-type holding method, incorporates a positive rake geometry, and delivers four usable cutting edges per insert, reducing per-edge tooling cost in production milling setups.

This insert is suited for milling applications in steel and hard material workpieces, including both roughing and finishing passes where a chamfered and honed cutting edge is beneficial. The right-hand orientation and flat-top chip breaker geometry make it a practical choice for face milling and shoulder milling operations. It is compatible with the 7792VXD09 cutter series. Typical users include CNC machinists and tooling specialists in precision manufacturing, job shops, and production machining environments.

• 0.031 inches corner radius (1/32 inches) for controlled edge engagement
• Screw-type insert holding method for secure, repeatable seating
• Right-hand cut orientation; compatible with 7792VXD09 cutter series

Compatibility

Designed for use with the 7792VXD09 cutter series. Primary workpiece materials are steel and hard materials (ISO material codes P and H). ANSI and ISO standard compliant per designation XDLW090408SRD.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Ensure the milling cutter body is fully de-energized and the spindle is locked before removing or seating inserts. Use the appropriate torx or hex key to torque the clamping screw according to the cutter body manufacturer's specification. Inspect the pocket seat and screw threads for debris or damage before indexing to a fresh cutting edge.
