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.

Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking.

Also known as fly cutters, these end mills clamp onto tool blanks to machine flat surfaces. As the cutter rotates, the tool blank creates a wide, shallow cut on the face of the workpiece.

Keep multiple sizes of end mills on hand so you have the right size when you need it.
