Kennametal 2390265 Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 2390265 is a solid carbide milling insert with ISO designation SPET10T3PPELGB2, designed for high-performance metal removal in demanding milling operations. It carries a triple-layer PVD coating — TiN, TiCN, TiN — that provides wear resistance and thermal stability across a range of cutting conditions. The insert features a square shape with a 90-degree included angle, a left-hand orientation, and a GB2 chip breaker geometry. With a 0.80 mm corner radius and an inscribed circle of 10.00 mm, it suits medium to finishing milling passes. It is held in place by a screw-type clamping system. Licensed machinists and tooling specialists install and index this insert on compatible milling toolholders.

This insert is rated for primary workpiece materials including steel, stainless steel, superalloys, and titanium — ISO material groups P, M, and S. The KC725M manufacturer grade is formulated for these demanding material applications, making it a practical choice for aerospace, energy, and general machining environments where tool life and edge stability are critical. The SPET series and GB2 chip breaker geometry are suited to both roughing and semi-finishing operations depending on feed and depth-of-cut parameters. It is sold in minimum order quantities of 5, with individual package quantities of 1.

Key Features

• Triple-layer PVD coating (TiN/TiCN/TiN) for wear resistance and edge toughness
• KC725M grade optimized for steel, stainless steel, superalloys, and titanium
• Square insert shape with 90-degree included angle and left-hand orientation
• GB2 chip breaker geometry for controlled chip evacuation
• Screw-type insert holding for secure, repeatable indexing
• 11-degree relief angle supports positive cutting action and reduced cutting forces

Compatibility

Designed for use in SPET-series milling toolholders that accept a square insert with a 10.00 mm inscribed circle, 0.1563-inch thickness, and screw-type clamping. Consult the toolholder specification sheet to confirm ISO seat geometry and insert orientation requirements before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating any insert. Use the correct torque driver or wrench specified by the toolholder manufacturer for the clamping screw — refer to the toolholder documentation for fastener requirements. Inspect the insert pocket and clamping seat for chips or wear before installing a new insert.
