Seco 02656007 Milling Insert Trigon Solid Carbide MP3000

Product Description

The SECO 02656007 is a trigon-shaped, solid carbide milling insert in the MP3000 manufacturer grade, designed for high-performance metal removal in milling applications. Coated with TiAlN via a PVD process, this insert handles steel, stainless steel, and hard materials with a positive rake angle of 7 degrees and a T-Land cutting edge style. The 12-degree relief angle and micrograin carbide substrate provide toughness and wear resistance at elevated cutting speeds. The insert measures 0.278 inches inscribed circle diameter and 0.109 inches thick, with a corner radius of 0.0315 inches. It is held in place by a screw and is a single-sided, neutral-hand insert. Licensed machinists and CNC tooling technicians select this insert for demanding milling operations on difficult-to-machine workpieces.

This insert is suited for use in milling cutters requiring a 100T trigon-style seat geometry. It targets applications involving steel, stainless steel, and hard materials where controlled chip evacuation and edge security are priorities. The M06 chip breaker designation is optimized for medium cutting conditions. Compatible cutter series include the R218.19-20 and R217.21-R100. The ANSI and ISO codes are both listed as 218.19-100T-M06, making cross-referencing against existing tooling setups straightforward for toolroom and production environments.

Key Features

• Solid micrograin carbide substrate with TiAlN PVD coating for heat and wear resistance
• Trigon shape with 60-degree included angle and 3 cutting edges per insert
• Positive rake angle (7 degrees) and T-Land cutting edge style for controlled cutting forces
• M06 chip breaker optimized for medium-condition milling of steel and hard materials
• Maximum depth of cut: 0.029 inches
• Neutral hand orientation for flexible cutter mounting
• Conforms to ISO standards; ANSI code 218.19-100T-M06

Compatibility

Compatible with milling cutter series R218.19-20 and R217.21-R100. Designed for toolholders accepting 218.19-100T series trigon inserts with screw-style clamping. Suitable for primary workpiece materials classified as hard material (H), with secondary application in steel and stainless steel (P and M material groups per ISO classification).

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC toolroom technician with the spindle fully stopped and machine power locked out per facility LOTO procedures. Use the appropriate torx or hex key to torque the clamping screw per the cutter body manufacturer's specification — do not over-torque, as this can fracture the carbide insert. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert. Confirm insert orientation and hand designation match the cutter body before resuming operation.
