Seco 03272716 RPKT1204M0T-6-M15 MP2501 Milling Insert

Product Description

The SECO 03272716 is a solid carbide round milling insert carrying ANSI and ISO designation RPKT1204M0T-6-M15 in manufacturer grade MP2501. This single-sided, positive-rake insert features a CVD-applied Duratomic coating combining TiCN and Al2O3 layers for thermal stability and wear resistance during milling operations. With 6 cutting edges, a 0.2362-inch corner radius, and a T-Land cutting edge style, it is engineered for productive material removal in steel and related alloys. Machinists and tooling technicians install this insert into compatible cutter bodies as an indexable replacement, making it a standard consumable on CNC milling centers.

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 the RPKT-12 series and is confirmed compatible with cutter series 335.18. The insert is held in the cutter body by screw clamping and is neutral-handed, making it adaptable across standard insert pockets of the correct geometry. Typical use cases include face milling and shoulder milling on production machining equipment in job shop and manufacturing environments. The MP2501 fine grain carbide substrate supports interrupted cuts and variable chip loads common in these applications.

Key Features

• 6 indexable cutting edges per insert for extended tool life between changeovers
• CVD Duratomic coating (TiCN plus Al2O3) for heat and wear resistance
• Positive rake angle (15 degrees) with T-Land edge preparation reduces cutting forces on steel
• Round insert shape provides full 360-degree included angle and smooth radial engagement
• M15 chip breaker geometry suited for steel, stainless steel, cast iron, superalloys, and titanium
• Compatible with cutter series 335.18; screw-held mounting for secure, repeatable seating

Compatibility

Compatible with SECO cutter series 335.18. Designed for use in RPKT-12 series insert pockets. Rated for primary workpiece material steel (ISO material code P) and secondary materials stainless steel (M), cast iron (K), and superalloys and titanium (S). ANSI and ISO code RPKT1204M0T-6-M15.

Installation Notes

Installation is performed by qualified machinists or tooling technicians following the cutter body manufacturer torque sequence for the insert clamping screw. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket seat and clamping screw condition at each changeover to ensure proper insert seating and prevent runout. Handle carbide inserts carefully to avoid chipping cutting edges prior to use.
