The 3400 Harmon-i-Cut is a 4-flute, high-performance end mill designed for brass, copper, cast iron, steels, stainless steels, titanium, and nickel-based super alloys, including Inconel. Its variable helix, unequal flute spacing, and varying rake help reduce harmonics and chatter while supporting longer tool life and higher material-removal rates in difficult-to-machine materials.
