Seco 10198800 Carbide Milling Insert Xomx 18 MP3501

Product Description

The SECO 10198800 is a single-sided carbide milling insert in the XOMX series, designed for right-hand cutting operations in face and shoulder milling applications. It carries a parallelogram shape with a positive rake angle of 15.9 degrees and a T-Land cutting edge style, which together reduce cutting forces and improve chip flow. The insert is coated with a multilayer TiCN, Al2O3, and Chrome stack applied through SECO's Duratomic coating process, delivering thermal resistance and wear life suited for production environments. With an inscribed circle of 0.4409 inches and a corner radius of 0.0315 inches (1/32 inch), this insert is built for general steel milling where consistent tool life matters.

This insert is intended for use in steel machining as the primary application, with secondary capability in stainless steel, cast iron, and superalloys and titanium. The MP3501 manufacturer grade spans material grades P20 through P40, K20 through K40, covering a broad range of workpiece hardness and condition. It is well-suited for production milling on CNC machining centers in both job shop and high-volume manufacturing environments. Cutter series compatibility is listed as R217/220.69-18. The ANSI and ISO code for this insert is XOMX180608TR-MD15 with the MD15 chip breaker geometry.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper seating and runout accuracy.
