Kennametal 3033728 Milling Insert EDPT140408PDERHD KC522M

Product Description

The KENNAMETAL 3033728 is a solid carbide milling insert with a TiAlN PVD coating, designed for indexable milling operations in demanding metal-cutting environments. It carries the ISO designation EDPT140408PDERHD and the ANSI code EP1408EHD, and features a parallelogram shape with a positive rake geometry. The HD chip breaker controls chip formation across a range of materials. At 0.1772 inches thick and 0.3299 inches wide, with a 0.0315-inch corner radius, this insert is engineered for consistent edge performance. It is installed by the screw-holding method and is a single-sided, right-hand insert with two cutting edges per piece.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. It is compatible with the Kennametal Mill 1-14 cutter series and is intended for use in production environments where tool life and chip control on difficult workpiece materials are priorities. Typical applications include face milling and shoulder milling on CNC machining centers in both job shop and high-volume manufacturing settings.

Compatibility

Compatible with the Kennametal Mill 1-14 cutter series. Designed for use with screw-type indexable milling cutter bodies that accept EDPT-style inserts in the 1408 size.

Installation Notes

This insert is installed by a machinist or toolroom technician using the appropriate torx or hex key for the clamping screw specified by the cutter body manufacturer. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces before torquing the clamping screw. Inspect the pocket for chips or debris prior to seating to avoid insert rocking or premature edge failure.
