Kennametal 5590777 Milling Insert EDPT180508PDERHD KCPM40

Product Description

The KENNAMETAL 5590777 is a solid carbide milling insert in the EDPT series, designed for high-performance face and shoulder milling operations. It carries the ISO designation EDPT180508PDERHD and ANSI code EP1808EHD. The insert features a dual PVD coating — TiAlN and AlCrN — applied over a solid carbide substrate in the KCPM40 grade. With a positive rake angle of 15 degrees, a honed cutting edge, and an HD chip breaker geometry, this insert is engineered to manage chip flow and reduce cutting forces in demanding applications. It accommodates a maximum depth of cut of 0.368 inches and offers 2 cutting edges per insert.

This insert is intended for milling steel, stainless steel, superalloys, and titanium — material application codes P, M, and S. It is a right-hand insert held in place by a screw-clamp method and is rated for single-sided use. Compatible with the Kennametal Mill 1-18 cutter series, it suits production milling environments in aerospace, general machining, and stainless fabrication where tool life and edge stability under heat are critical. Licensed machinists and CNC tooling specialists are the primary installers and users of this insert.

Key Features

• KCPM40 solid carbide grade with dual PVD TiAlN and AlCrN coating for extended tool life in difficult-to-machine materials
• Positive 15-degree rake angle reduces cutting forces and heat generation at the edge
• HD chip breaker geometry promotes controlled chip evacuation in steel and superalloy cuts
• Honed cutting edge style improves edge strength and reduces chipping risk
• Maximum depth of cut of 0.368 inches suits both roughing and semi-finishing passes
• Screw-clamp holding method provides secure, repeatable insert indexing

Compatibility

Designed for use with the Kennametal Mill 1-18 cutter series. Insert size code 1808, ISO designation EDPT180508PDERHD, ANSI code EP1808EHD. Right-hand orientation; confirm cutter body handedness before ordering.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the spindle before handling or replacing inserts. Use the correct torque driver for the screw-clamp fastener — follow the cutter body manufacturer's torque specification for the insert screw. Inspect the insert pocket for damage or debris before seating a new insert, and verify proper seating before resuming cuts.
