What is Carbide ?
Carbide is one of the hardest material to be found and has amazing
wear resistance capabilities that make it ideal for the many tasks
it performs .Not only is it very hard ,but it is able to withstand
a great deal of abrasion,which enables the carbide cutting tools to
outperform other material .All our end mills are produced from
solid carbide material .
