Roughing Cobalt Steel Square End Mills for Aluminum, Brass, and Bronze
 |
A higher helix angle means these end mills clear more chips than other roughing cobalt steel end mills, making them better for milling aluminum, brass, and bronze. Serrations along the cutting edge act as chip breakers, so they can remove large amounts of material at high speeds. End mills are cobalt steel, which has better heat and wear resistance than high-speed steel, so they can run at higher speeds. All are center cutting, allowing plunge cuts into a surface.
