Product Description
The SECO 03280726 is a round milling insert designed for indexable milling operations in demanding metal-cutting applications. Manufactured from fine-grain solid carbide and coated with TiSiN and TiAlN via a PVD coating process, this insert delivers wear resistance and thermal stability during high-speed milling. The ANSI/ISO designation is RDHT10T3M0T-8-M11, belonging to the RDHT-10 series. It features 8 cutting edges, a positive rake angle of 16 degrees, and a T-Land cutting edge style. The chip breaker designation is M11, suited for medium machining conditions. Licensed machinists and CNC tooling specialists install this insert in compatible indexable milling cutter bodies.
This insert is intended for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material grades P, M, and S. It is a single-sided insert with a neutral hand orientation and a relief angle of 15 degrees. The round shape provides a full 360-degree included angle, enabling consistent radial engagement and smooth surface finishes on contoured or flat workpieces. Typical applications include face milling, ramping, and helical interpolation on CNC machining centers in both production and job-shop environments. The insert is held in the cutter body via a screw-clamping method.

- TiSiN and TiAlN dual PVD coating for elevated heat resistance and extended tool life
- Positive rake geometry (16-degree rake angle) reduces cutting forces on difficult materials
- T-Land cutting edge style provides edge strength during interrupted or high-feed cuts
- M11 chip breaker optimized for medium-duty milling of steel, stainless steel, and titanium
- Maximum depth of cut of 0.1969 inches; screw-held insert for secure positioning in the cutter body
Compatibility
Compatible with SECO cutter series R217.29-05 and R220.29-05 as specified by the manufacturer. Insert size code is 10T3 per ANSI and ISO standards.
Installation Notes
Installation is performed by CNC machinists or tooling specialists. Always power down and lock out the machine spindle before seating or indexing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to secure the clamping screw do not overtighten or use impact drivers on insert screws. Inspect the insert pocket and screw threads for debris or damage before seating a new insert to ensure proper seating and runout.
