Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions

It is a special type of four high rolling mill in which each of the two working rolls is backup by two or more of the larger backup rolls for rolling hard in materials. It may be necessary to employ work rolls of a very small diameter but of considerable length. In such cases adequate of the working rolls can be obtained by using a cluster mill.

A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable. Carbide vs HSS End Mills

The selection of an appropriate drill point angle for your bit should be informed by questions about your application. Yes—a hole is a hole is a hole—but what is the purpose of the hole, what type of metal are you cutting into, and what are the specifications for the finished hole? In addition to the drill point angle, factors that can affect successful drilling include:
across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the rewind shaft must increase at a linear ratio, relative to roll diameter, as a rewind ...
The thread mill can place threads closer to the bottom of a blind hole, and it can machine threads in big holes with ease. The thread mill leaves room for chips to fall away. And the thread mill, unlike a tap, can combine various holemaking operations into a single tool. In short, there is a great deal that a thread mill .

The WINertia™ AV Spreader roll, or bowed roller, is created by machining a taper at the center of the WINertia AV idler for a "Reverse Crown" profile. The tapered dead shaft roller creates a larger diameter at the outer edge and a smaller diameter at the roll center. This design creates a greater surface speed at the ends of the roll.
A fourhigh mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced:
