Seco 02828090 Milling Insert LOEX080404TR-M08 MK2050

Product Description

The SECO 02828090 is a solid carbide milling insert carrying the ANSI and ISO designation LOEX080404TR-M08 and manufactured to grade MK2050. This double-sided, rectangular insert features four cutting edges with a T-Land cutting edge style, a negative rake geometry at 33.3 degrees, and a 0-degree relief angle. The insert measures 0.3661 inches in length, 0.1732 inches in inscribed circle diameter, and 0.2626 inches thick. A PVD-applied dual-layer TiSiN and TiAlN coating delivers wear resistance and thermal stability suited to high-productivity milling operations. The screw-holding method and right-hand orientation make it a direct fit for compatible SECO cutter bodies. This insert is intended for use by machining professionals and toolroom technicians.

This insert is designed primarily for milling cast iron, steel, and hard materials. It fits within the LOEX-08 series and is compatible with SECO cutter series R217.94-08 and R220.94-08. The M08 chip breaker geometry supports controlled chip evacuation in medium-grain carbide grade applications. Typical use cases include face milling and shoulder milling in production environments where consistent tool life across cast iron and steel workpieces is required. The insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before seating or replacing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer to achieve proper clamping torque on the mounting screw. Inspect the insert pocket and clamping screw for damage or contamination before installing a new insert.
