Slab mills are not that common with modern CNC machining centres. Rather, they are still used with manual milling machines to quickly machine large surfaces. That is also why slab milling is often called surface milling.
The slab itself spins in a horizontal position between the spindle and the support.
A predecessor for the end mill. Side-and-face cutters have teeth around the circumference as well as on one side. This makes the functionality very similar to end mills but their popularity has waned over the years with the advancement of other technologies.
There is a special cutting tool for milling involute gears. There are different cutters available to produce gears within a certain number of teeth.
These tools have the same function as face mills. They consist of a central body that holds either one or two tool bits (double-end fly cutters).
Face mills are better for high quality cutting. Fly cutters are just cheaper and the cutting bits are often made at the shop by a machinist rather than bought from stores.
Hollow mills are basically the opposite of face mills. Here, the workpiece is fed into the inner part of the mill to produce a cylindrical outcome.
As the name says, these are pretty much end mills with a slight difference. The roughing end mill has jagged teeth. These make the cutting process faster than with a regular end mill.
The cut bits of metal are smaller than usual and therefore easier to clear. Multiple teeth come into contact with the workpiece at the same time. This reduces chatter and vibration, which could otherwise be larger because of the jagged teeth.
Woodruff, or keyseat/keyway cutters are used to cut keyslots into parts, for example shafts. The cutting tools have teeth perpendicular to the outside diameter to produce suitable slots for woodruff keys.
