The 38 degree helix angle and unequal flute spacing ensure smooth, quiet operation while the open 5-flute design provides efficient chip evacuation. 5-Speed end mills are designed for high-speed machining while utilizing the entire length of the cutting edge. The dished center of the face geometry allows for ramp angles exceeding 10 degrees.
5-flute with corner radii (short through XL lengths, inch diameters)
5-flute with corner chamfer and chipbreakers (std and long, inch or metric)
5-flute with corner radius and chipbreakers (long length, metric)
With a 32 degree helix angle and unequal flute spacing, this 7-flute end mill offers extreme productivity with reduced contact points and low-vibration machining. The 7-Speed family of end mills have a specialized face geometry allowing the tool to step down 5% of the diameter per revolution in helical milling applications.
