Seco 02827583 Milling Insert LOEX080404TR-M08 F40M Carbide

Product Description

The SECO 02827583 is a solid carbide milling insert in the LOEX-08 series, carrying the ANSI and ISO designation LOEX080404TR-M08. This double-sided, right-hand insert features four cutting edges and a TiAlN and TiN PVD coating over a fine-grain carbide substrate in manufacturer grade F40M. The rectangular insert has an inscribed circle of 0.1732 inches, a thickness of 0.2626 inches, and a corner radius of 0.0157 inches (1/64 inch). Designed for use in indexable milling cutters, it is installed and replaced by machinists and tool-crib technicians working in production or job-shop environments.

This insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its primary material codes are P, K, and S, with secondary coverage for K and N workpiece categories. The M08 chip breaker geometry and negative rake angle support stable cutting action across a broad range of material hardnesses and feed conditions. Compatible cutter series include R217.94-08 and R220.94-08, making it a direct-fit indexable insert for those tool bodies in face milling and shoulder milling applications.

Key Features

• Solid carbide fine-grain substrate in grade F40M for toughness and wear resistance in interrupted and continuous cuts
• TiAlN and TiN PVD coating for elevated heat resistance and extended tool life on steel and superalloys
• Double-sided insert with 4 cutting edges maximizes the number of indexes per insert
• M08 chip breaker geometry with negative rake (33.3 degrees rake angle) and T-Land cutting edge style for stable cutting action
• Maximum depth of cut of 0.3268 inches and cutting edge effective length of 0.3268 inches
• Screw-clamped insert holding method for positive seating and repeatable indexing

Compatibility

Compatible with SECO cutter series R217.94-08 and R220.94-08 tool bodies. Designed for use in face milling and shoulder milling applications where the LOEX-08 insert seat is specified.

Installation Notes

Installation and indexing of milling inserts should be performed by a qualified machinist or toolroom technician with the spindle powered off and the machine locked out per established lockout/tagout procedures. Use the appropriate Torx or hex key to seat the clamping screw to the tool body manufacturer's specified torque range for LOEX-08 seats. Inspect the insert pocket and seating surfaces for chips or debris before seating a fresh insert. Handle solid carbide inserts carefully to avoid chipping the cutting edges prior to use.
