Kennametal 3033724 Milling Insert EDPT140412PDERHD KC725M

Product Description

The KENNAMETAL 3033724 is a solid carbide milling insert designed for high-performance metal removal in demanding machining environments. It carries the ISO designation EDPT140412PDERHD and the ANSI code EP1412EHD, with a KC725M manufacturer grade and a PVD-applied TiAlN coating. The parallelogram-shaped, single-sided insert features two cutting edges, a positive rake geometry, and a 15-degree relief angle. The HD chip breaker and honed cutting edge style make it well suited for interrupted cuts and finishing passes where edge stability and chip control are critical. Licensed machinists and CNC tooling specialists are the primary installers and users of this insert.

This insert is engineered for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. It is compatible with the Kennametal Mill 1-14 cutter series. Typical applications include face milling, shoulder milling, and contouring operations on CNC machining centers where consistent surface finish and tool life across difficult-to-machine alloys are required. The right-hand orientation and screw-holding method are standard for this cutter platform.

Key Features

• PVD TiAlN coating provides heat resistance and extended tool life in steel and superalloy cutting
• HD chip breaker geometry controls chip flow during moderate to heavy milling passes
• Positive rake and 15-degree relief angle reduce cutting forces on workpiece and spindle
• Honed cutting edge style improves edge toughness and reduces micro-chipping
• Two usable cutting edges per insert maximize cost-per-edge value
• Screw-holding method provides secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with the Kennametal Mill 1-14 cutter series. Insert size code 1412 with ISO designation EDPT140412PDERHD and ANSI code EP1412EHD. ANSI and ISO standards compliant.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Always power down and lock out the machine spindle before seating or indexing inserts. Use the manufacturer-specified torx or hex key to secure the clamping screw to the cutter body — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper contact and runout.
