What are the 3 types of milling cutters?

November 17, 2022

When it comes to milling cutters, there are three main types: end mills, shell end mills, and face mills. Each has its own respective uses and applications. Read on to learn more about each type of cutter and how they’re used.

End Mills

End mills are one of the most common types of milling cutters. They are typically used for cutting aluminum, brass, bronze, and other metals. They can also be used for cutting wood and plastic. End mills have a square or rectangular shaped cutting end, and they are available in a variety of sizes.

Roughing End Mills

Roughing end mills are designed to remove large amounts of material quickly. They are typically used in milling operations where a large amount of material needs to be removed, such as in the machining of castings and forgings. Roughing end mills have a large, wide cutting head with sharp teeth. The cutting head is typically mounted on a spindle that can be rotated at high speeds. Roughing end mills are generally used in conjunction with other types of milling cutters, such as finishing end mills.

Ball Nose End Mills

Ball nose end mills are one of the most commonly used types of milling cutters. They are used for machining round, tapered, and contoured surfaces, as well as for drilling, reaming, and countersinking. Ball nose end mills have a rounded tip that is designed to machine curved surfaces. The curve of the ball nose can be varied to produce different results. For example, a shallower ball nose end mill will produce a smoother finish on a surface than a deeper ball nose end mill.

Ball nose end mills are available in a variety of sizes and shapes. The most common size is the 1/2" diameter shank with a 3/16" radius cutting edge. Other sizes include 1/4" and 3/8" diameter shanks with 1/8", 3/16", 1/4", and 3/8" radius cutting edges. Ball nose end mills can also be found in metric sizes.

Chamfer Mill

Chamfer mills, also known as chamfer end mills or deburring end mills, are designed to create angled chamfers on the edges of machined parts. These cutters can be used to remove burrs from the edges of metal plate or bar stock, or to create decorative chamfered edges on machined parts. Chamfer mills typically have a 45-degree cutting angle and are available in a variety of sizes and shank styles to suit different applications.

Dovetail Cutter

A dovetail cutter is a type of milling cutter that is used to create dovetails. This is done by first creating a series of cuts with the cutter that are parallel to each other. Once these cuts are made, the cutter is then rotated and the same process is repeated. This creates a series of interlocking cuts that form the dovetail shape.

Involute Gear Cutters

Involute gear cutters are one of the most popular types of milling cutters. They are used to cut gears with an involute tooth form. The cutter has a conical body with teeth that are shaped like an involute curve. The cutter is rotated around a gear blank to cut the teeth into the desired shape.

Involute gear cutters can be used to cut gears with either a straight or helical tooth form. The cutter can be rotated in either direction to produce the desired tooth form. The depth of each tooth can be controlled by adjusting the height of the cutter body.

Involute gear cutters are available in a variety of sizes and shapes. They can be made from high speed steel or carbide for increased durability.
