A thread mill is simply an end mill with the thread form and a specific pitch. The machine can be programmed to helically interpolate to the desired diameter. A 1/4-20 thread mill can produce a 1/2-20 or even a 7/8-20 thread making it an excellent choice for uncommon thread sizes or large diameter threads.

During contour milling we recommend a lateral infeed of approx. 25 % of the end mill diameter while applying 100 % immersion depth. The immersion depth is conditional to the milling motor, the structure and the stability of the machine. This means a reduction of the values is required, when using a less powerful and / or lighter milling motor.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
