However, using an ordinary tap or die to clean threads generally ...
Working from engineering drawings developed by the toolmaker, engineers or technologists, tool makers lay out the design on the raw material (usually metal), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, and jig grinders), power tools (such as die grinders and rotary tools), and hand tools (such as files and honing ...
A thread restorer is a tool used to fix threads on nuts or bolts that have become damaged. One type of thread restorer is a thread restoring file or thread file. [1] There are other types of thread restoring tools as well, for example a chaser tap or chaser die. [2] Normal taps and dies can also be used to clean up a thread, which is called ...
In manufacturing, threading is the process of creating a screw thread.More screw threads are produced each year than any other machine element. [1] There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such as ...
A die head is a threading die that is used in the high volume production of threaded fasteners. Die heads are commonly used on lathes, turret lathes, screw machines and CNC lathes. They may be used for either cutting a thread or rolling a thread. They may also be used for internal or external thread cutting.

The different punches and dies determine the shape and angle (or curvature) of the newly made section of the material. The dies and punches are needed to be made of tool steel to withstand the repetitious nature of the procedure. [2]
