Iscar 5621380 Milling Tip 0.312 in 3 Flute IC908 Carbide

Product Description

The ISCAR 5621380 is a carbide end replaceable milling tip designed for use in the Multimaster MM EC-3 interchangeable-head milling system. It carries an IC908 sub-micrograin carbide grade with a PVD-applied TiAlN coating, making it well suited for demanding material removal applications. The tip has a 0.312-inch cutting diameter, a 0.390-inch functional length, and a maximum depth of cut of 0.200 inches. With a 3-flute geometry, a 90-degree lead angle, and a 45-degree helix angle, it delivers stable, efficient cutting action across a range of workpiece materials. Licensed machinists, tool and die technicians, and CNC operators working in production or job shop environments are the typical end users.

This tip is intended for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its right-hand cutting geometry and TiAlN coating make it a practical choice for finishing and semi-finishing passes where surface integrity and tool life are priorities. The MM EC-3 series platform allows fast tip changes at the machine without removing the holder from the spindle, reducing downtime in high-mix environments.

Installation Notes

Installation and removal of replaceable milling tips should be performed by qualified machinists or tooling technicians following the holder manufacturer's torque and engagement procedures. Ensure the spindle is fully stopped and locked out before changing tips. Inspect the holder interface and mating threads for chips or damage before seating the tip. Do not exceed the recommended depth of cut or radial engagement for the listed grade and coating.
