The milling depth and width determine the size of the mill cutting tools. An increase in width and depth before mill tooling means an increase in the size of the milling cutter. However, Φ16～Φ630mm is the standard index milling cutter diameter range.
When milling parts with a large surface area, the recommendation is to use milling cutters with smaller diameters. Ideally, during any milling operation, 70% of the cutter’s cutting edges should take part in cutting.
Another factor that can determine the diameter of the milling cutter is the diameter of the machine tool spindle. The recommendation for selecting a face milling tool diameter is D = 1.5d, where d is the spindle diameter.
Also, when milling holes, the size of the tool also requires great attention because if the milling cutter diameter is too large or too small compared to the hole, it could cause damage to the workpiece or tool.
When selecting the right milling cutter, the major factors to consider are cutting power and workpiece processing size. For instance, when selecting the diameter of a face mill cutting tool, the power requirement of the tool should be within the power range of the milling machine cutting tool.
In addition, for a small diameter end mill, the machine’s maximum revolution meeting the minimum tool cutting speed (60m/min) should be the main consideration.
When choosing a milling tool, the number of teeth on the tool is an important consideration. A dense-tooth milling tool can have 8 teeth with a diameter of 100mm, while a coarse-tooth tool with the same diameter has only 6 teeth. Coarse metal milling tools are ideal for rough machining due to their large chip flute, which reduces friction between the workpiece, cutter body, and the chip itself.
Besides, it is important to note that a dense-toothed milling tool’s cutting load per tooth is smaller than that of a coarse-toothed milling tool at an equal feed rate.
Using a grinding blade is the best option for fine milling tooling. This type of insert provides improved dimensional precision while increasing the placement accuracy of the cutting edge during milling, allowing for better surface roughness and machining accuracy. However, it is preferable to utilize a pressed blade for roughing because it can lower the cost of processing.
Moreover, using carbide inserts without sharp rake angles would reduce the tool service life, especially with small cutting depths and small feeds.
Milling cutter tools are important to any milling process because these tools are attached to a milling machine to remove or cut materials into different shapes used for various operations. These milling tools come in different types for different milling purposes. It is recommended to consult a specialist for professional advice.

What is the difference between end mill and face mill?
The major difference between a face mill and end mill is that end mills use both the cutter’s end and sides, while face milling is for horizontal cutting.
How are end mills used?
End Mills can make specific shapes and holes in a workpiece during industrial processes such as milling, profiling, contouring, reaming, slotting, counterboring, and drilling operations. End mills have cutting teeth on the face and body edge. They work great for cutting various materials in different directions.
What is the difference between drill bits and milling cutters?
There are several differences between a milling cutter and a drill bit. However, understanding their function can be a major pointer to accurately separating them. A drill bit is a perfect tool for making holes in a workpiece, so it must have an apex angle to help it orient, whereas the milling cutter is used to mill the plane, so there is no apex angle.
Also, The drill bit has a tapered bottom to allow tool tip penetration, whereas the bottom of a mill cutter is flat.
