Cobalt End Mills

Cobalt end mills are a high quality end mill. We sell only cobalt end mills made in the USA. Cobalt end mills may be used in many applications as well as for cutting a wide range of materials. One of the most important factors to consider while using cobalt end mills is the "Speed". Although nobody´s carts are perfect, they serve as a good "guideline" or "starting point". Since all situations vary, "trial and error" is the best way to find the correct formula for your job. Remember to write down what speed work best for your particular job. Simple rules to keep in mind are that when you are working with hard or abrasive materials, a slower speed and feed rate is recommended. The slower rate will extend the life of your tool. If you are working with softer materials, a higher speed can be used. Usually the higher speeds will yield a smother finish.

Corner radius and cobalt roughers are two more choices in the cobalt end mill family. The cobalt radius end mills are for those jobs that require a radius on the cutting edge. We stock our corner radius end mills in the popular sizes with radiuses from .020, .030, .045, .060. Cobalt rougher end mills are used when you need to remove a lot of material quickly and are not concerned with the finish. We stock both coarse and fine cut.
