Kennametal 7026548 DCMT3252MF KCP25C Turning Insert

Product Description

The KENNAMETAL 7026548 is a DCMT3252MF-style carbide turning insert in grade KCP25C, designed for precision metal cutting on CNC lathes and turning centers. It features a multilayer CVD coating of TiCN and Al2O3 (aluminum oxide) over a carbide substrate, providing thermal resistance and wear protection at elevated cutting speeds. The insert has a diamond shape with a 55-degree included angle, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a neutral hand orientation. The MF chip breaker geometry produces a chamfered and honed cutting edge suited to light-to-moderate finishing passes. Licensed machinists and CNC turning specialists install this insert using the screw-on holding method.

This insert is rated for turning, facing, boring, back turning, and back boring operations. Primary workpiece materials are steel (ISO P) and cast iron (ISO K). The 55-degree diamond profile allows access to tight shoulders and contoured profiles. The positive rake geometry reduces cutting forces, making it well suited to finishing and semi-finishing passes where surface finish and dimensional control are priorities. It conforms to both ANSI and ISO standards and carries the ISO designation DCMT11T308MF.

Compatibility

Designed as a screw-on replacement turning insert for tool holders accepting DCMT3252 (DCMT11T3) style inserts. Compatible with multi-use turning applications including turning, facing, boring, back turning, and back boring. Primary workpiece material codes P (steel) and K (cast iron) per ISO classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling specialists. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and tighten the retaining screw to the tool holder manufacturer's specified torque using the correct Torx or hex key. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
