A die head is a threading die that is used in the production of threaded components to cut a variety of threads. Die heads are commonly used on lathes, turret lathes, screw machines and CNC lathes. In operation, there are usually four moveable chasers that cut the thread then back away from the work to permit rapid removal of the tool. Each set of chasers is designed to cut a different thread. One set of chasers would be used at a time, each chaser is inserted into the die head (in the correct numerical order) and the die head is closed bringing the chasers down to their cutting position. When correct length of thread has been cut the die head will open allowing for rapid retraction of the head without interference with the newly formed thread.
The advantages of using Coventry Dies over conventional single point threading tools are: much faster production time, uniform thread sizes, neater threads than single point tools, inexpensive, large variety of chasers available (metric and imperial pitches), can cut left and right hand threads, Chasers can be sharpened for longer life, easy to use no special training needed.
