Ingersoll Cutting Tools 2900859 Milling Insert IN4030

Product Description

The INGERSOLL CUTTING TOOLS 2900859 is a solid carbide milling insert engineered for demanding material removal applications in metalworking environments. Manufactured to grade IN4030 with a coarse grain carbide substrate, this insert features a 55-degree parallelogram (diamond) shape and carries a dual-layer TiAlN and AlCrO coating applied via PVD process. The coating provides thermal resistance and hardness retention at elevated cutting temperatures. With four usable cutting edges and a T-Land cutting edge style, this insert is suited for high-productivity milling on machining centers and milling machines operated by skilled machinists and CNC programmers.

This insert is designed for use on steel, stainless steel, cast iron, superalloys, and titanium workpieces, covering ISO material groups P, M, K, and S. It is compatible with the EF6J cutter series and is intended for left-hand insert orientation. Typical applications include face milling, shoulder milling, and profile milling in production shop environments where tool life and edge stability across difficult-to-machine alloys are primary concerns. The negative rake geometry supports stable cutting action under interrupted or heavy-feed conditions.

Key Features

• Solid carbide construction with coarse grain substrate for toughness and wear resistance
• Dual-layer TiAlN and AlCrO PVD coating for high-temperature performance
• 55-degree parallelogram shape with four usable cutting edges, double-sided insert
• T-Land cutting edge style with negative rake for stable, controlled cuts
• Left-hand insert orientation; screw-held mounting method
• ANSI and ISO compliant: ANSI/ISO code DFH324L001 K IN4030

Compatibility

Compatible with the EF6J cutter series. Designed for left-hand insert seating in DFH series toolholders. Verify pocket geometry and insert size code 324 before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Disengage machine power and lock out the spindle before handling or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified torque as noted in the cutter body documentation. Inspect the insert pocket for debris, damage, or wear before seating the new insert to ensure proper contact and edge alignment.
