Kennametal 2983890 Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 2983890 is a solid carbide milling insert manufactured to ISO code EDCT140404PDERGD and ANSI code EC1404EGD. It carries the KC725M manufacturer grade and features a TiAlN coating applied via PVD process, delivering thermal resistance and wear life in demanding cutting applications. The insert is parallelogram-shaped with a 70-degree included angle, a positive rake geometry, and a honed cutting edge style. Two cutting edges are available per insert. Thickness measures 0.177 inches and inscribed circle diameter is 0.3341 inches. The GD chip breaker geometry supports controlled chip formation across a range of material types. Licensed metalworking professionals and tooling specialists install and index this insert in compatible milling cutter bodies.

This insert is engineered for milling steel, stainless steel, superalloys, and titanium, corresponding to material grade classifications C5, C6, and C7 and ISO work material codes P, M, and S. The right-hand, single-sided design and screw-holding method make it straightforward to index in the field. It is suited for use in EDCT-series toolholders, specifically within the Mill 1-14 cutter series. Typical applications include face milling, shoulder milling, and profile milling in production or job-shop environments where consistent insert geometry and coating performance are required across difficult-to-machine alloys.

Key Features

• KC725M grade with TiAlN PVD coating for extended tool life in steel, stainless, and superalloy milling
• Parallelogram insert shape (EDCT series) with 70-degree included angle and positive rake
• GD chip breaker geometry for controlled chip formation
• Two cutting edges per insert, right-hand orientation, single-sided
• Honed cutting edge style reduces micro-chipping on difficult workpiece materials
• Screw-holding method for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with Mill 1-14 cutter series toolholders designed for EDCT-series inserts. Insert size code 1404 with inscribed circle range of 0.3000 to 0.3500 inches and length range of 0.6500 to 0.7000 inches. Conforms to ANSI and ISO standards as identified by ANSI code EC1404EGD and ISO code EDCT140404PDERGD.

Installation Notes

Installation and indexing should be performed by qualified machinists or tooling technicians. Shut down and lock out the machine spindle before removing or seating inserts. Use the appropriate torx or hex key to secure the clamping screw to the cutter body seat; verify the insert is fully seated against the pocket walls before tightening. Inspect the pocket for chips or debris before installing a new cutting edge to avoid seating errors that reduce tool life or cause insert fracture.
