Seco 74079714 Milling Insert F30M Solid Carbide Trigon

Product Description

The SECO 74079714 is a solid carbide trigon milling insert carrying manufacturer part number 218.19-100T-M06 and grade F30M. It features a TiAlN and TiN dual-layer PVD coating applied over a micrograin carbide substrate, providing wear resistance across a broad range of cutting applications. The insert has a positive rake angle of 7 degrees, a T-Land cutting edge style, and a 12-degree relief angle. Inscribed circle measures 0.278 inches, thickness is 0.109 inches, and the corner radius is 0.0315 inches. The neutral hand orientation suits standard milling setups without requiring mirrored tooling. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is rated for universal primary workpiece material compatibility, with specific suitability for steel, stainless steel, cast iron, and hard materials. The M06 chip breaker geometry supports stable chip formation in both light and moderate feed-rate applications. Maximum depth of cut is 0.029 inches, making this insert well suited to finishing and semi-finishing operations. The three cutting edges allow index cycling before replacement, reducing per-edge tooling cost in production environments. It conforms to ISO standards and carries ANSI and ISO code 218.19-100T-M06.

Key Features

• Positive rake (7 degrees) with T-Land edge prep reduces cutting forces on difficult materials
• M06 chip breaker geometry supports controlled chip evacuation in steel and stainless steel
• Neutral hand insert compatible with screw-lock clamping systems
• ISO-standard geometry with ANSI code 218.19-100T-M06 for easy cross-referencing

Compatibility

Compatible with cutter series R218.19-20 and R217.21-R100 as stated by the manufacturer. Insert size code is 100T within the 218.19-100 series.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. De-energize and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to the toolholder manufacturer's specified procedure when seating the screw-lock clamp — do not over-torque the clamping screw. Inspect the insert pocket and clamp seat for chips or debris before seating a new insert to ensure proper contact and repeatability.
