Detailed Specificatoin

These Kedel square end four flute stub length carbide end milling cutters feature a 30 helix angle and are center cutting for plunging, slotting and profiling. As with all of our solid carbide tools, these stub end mills are manufactured using state-of-the-art machinery, manufacturing processes and inspection techniques, making them the preferred choice of carbide endmills for machinists wanting to produce high quality parts with maximum tool life. The addition of our ALTiN coating allows for increased speeds & feeds as well as longer tool life.

1. Fully enables running at rough machining parameters, resulting in finish surface quality.
2. Excellent performance in machining titanium, stainless steel and high temperature alloys.
3. The coating provides longer tool-life or increased cutting-values.
4. Suitable for all types of steel or metal.
