Seco 03272681 Milling Insert MP2501 Solid Carbide Trigon

Product Description

The SECO 03272681 is a solid carbide trigon milling insert in manufacturer grade MP2501, designed for high-performance metal removal in CNC milling applications. It carries a dual CVD coating of TiCN and Al2O3 under the Duratomic coating classification, which provides thermal resistance and wear protection during continuous and interrupted cuts. The insert features a positive rake angle of 7 degrees, a T-Land cutting edge style, and a neutral hand orientation. With three cutting edges and a corner radius of 0.0157 inches, it delivers consistent chip control across a range of ferrous materials. Installation is performed by licensed machinists or toolroom technicians using screw-type insert holders.

This insert is intended for milling steel as its primary workpiece material, with rated secondary applications in stainless steel, cast iron, superalloys, and titanium. It fits within the Series 218.19-080 and is compatible with cutter bodies in the R217.21 and R220.21-R080 series. The M04 chip breaker geometry supports moderate cutting depths up to 0.0240 inches maximum depth of cut, making it well suited for finishing and semi-finishing passes on a variety of ferrous and exotic alloy workpieces in both production and job shop environments.

Key Features

Compatibility

Compatible with cutter bodies in the R217.21 and R220.21-R080 series. ANSI and ISO code: 218.19-080T-M04. Verify insert pocket specifications against cutter body documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torque driver for the screw-type insert holding method to avoid over-torquing the clamping screw. Inspect the insert pocket for debris or damage before seating a new insert.
