Kennametal 3051552 Milling Insert EDPT140404PDERHD KC522M

Product Description

The KENNAMETAL 3051552 is a solid carbide milling insert carrying ISO designation EDPT140404PDERHD and manufacturer grade KC522M. It features a TiAlN coating applied via PVD process, delivering heat and wear resistance suited to high-speed milling operations. The insert has a parallelogram shape with a 70-degree included angle, positive rake geometry, and a honed cutting edge style. With 2 cutting edges and an HD chip breaker, it is designed for productive material removal across a range of workpiece materials. Licensed machinists and tooling specialists install this insert in compatible indexable milling cutters.

This insert is intended for milling steel, stainless steel, cast iron, superalloys, and titanium, corresponding to material grade codes P, M, K, and S. The right-hand orientation, positive rake, and HD chip breaker geometry make it well suited to roughing and semi-finishing passes in production milling environments, both on CNC machining centers and manual knee mills. It is compatible with the Mill 1-14 cutter series and is held in the cutter body by a screw-clamp method.

Key Features

• Solid carbide substrate with PVD TiAlN coating for elevated wear and heat resistance
• HD chip breaker design promotes efficient chip evacuation across multiple workpiece materials
• Positive rake geometry and honed cutting edge reduce cutting forces at the tool-workpiece interface
• Two cutting edges per insert maximize usable life before replacement
• Right-hand cutting orientation with screw-clamp insert holding method
• Meets ANSI and ISO insert standards; ANSI code EP1404EHD, ISO code EDPT140404PDERHD

Compatibility

Designed for use with the Kennametal Mill 1-14 cutter series. Insert style EDPT, insert size code 1404. Verify cutter body seat geometry and hand orientation before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the manufacturer-specified torx or hex key to secure the clamping screw, and never exceed the cutter body's rated speed and depth-of-cut parameters. Inspect the seat pocket for damage or debris before seating the new insert.
