They are designed with cutting teeth on the face and edge of the body and can be used to cut a variety of materials in several directions.

Why is an end mill called an end mill?

While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills.

What is the most common end mill?

Square end mills
Square end mills are the most common ones and can be used for many milling applications, including slotting, profiling and plunge cutting. Corner-radius end mills have slightly rounded corners that help distribute cutting forces evenly to prevent damage to the end mill and extend its life.

What is the difference between an end mill and a drill?

There are a number of significant differences between an end mill and a drill bit. The most obvious one is their function. A drill bit is designed to bore straight down into the material – metal, plastic, or wood – whereas an end mill is designed for sideways cutting. The two cannot be interchanged.
