Seco 02765956 Milling Insert XNEX040304TR-M08 MP3000

Product Description

The SECO 02765956 is a solid carbide trigon milling insert carrying the ANSI and ISO designation XNEX040304TR-M08 in manufacturer grade MP3000. This double-sided insert features a PVD-applied TiAlN coating over a micrograin carbide substrate, delivering six usable cutting edges per insert. It is designed for negative-rake milling applications with a T-Land cutting edge style and a 1/64-inch (0.0157 inches) corner radius. The insert measures 0.2638 inches across the inscribed circle and 0.1295 inches thick, with a maximum depth of cut of 0.1575 inches. It is installed and replaced by CNC machinists and tooling technicians working on milling centers in production and job-shop environments.

This insert is suited for milling hard materials, steel, and stainless steel, corresponding to workpiece material codes H, P, and M. The negative rake geometry and TiAlN coating make it appropriate for interrupted cuts and harder workpiece applications where edge durability is a priority. The T-Land edge prep and M08 chip breaker geometry support controlled chip formation in these material categories. Typical install scenarios include face milling and shoulder milling operations on CNC vertical and horizontal machining centers requiring a right-hand insert orientation in the XNEX-04 series insert pocket.

Key Features

• Double-sided insert with 6 cutting edges per insert, lowering per-edge tooling cost
• PVD TiAlN coating over micrograin solid carbide substrate for wear resistance in hard and ferrous materials
• T-Land cutting edge style with negative rake angle of 27 degrees for edge strength
• M08 chip breaker geometry for controlled chip evacuation in steel and stainless steel
• 1/64-inch corner radius (0.0157 inches) for general milling profiling and shoulder work
• Screw-held insert mounting method for positive, repeatable seating in compatible toolholders

Compatibility

Compatible with SECO cutter series R217.96-04 and R220.96-04. Conforms to ANSI and ISO standard designation XNEX040304TR-M08. Sold individually; minimum order quantity is 10 units.

Installation Notes

Insert replacement is performed by CNC tooling technicians following machine lockout and spindle-stop procedures before accessing the cutter body. Use a calibrated torque screwdriver appropriate for the cutter body screw specification — refer to the cutter body documentation for the correct fastener torque value, as it is not specified here. Inspect the insert pocket seating surface for chips or debris before seating the new insert. Handle carbide inserts with care to avoid chipping cutting edges prior to use.
