What are the different types of thread cutting dies?

There are two main types of threading dies, solid and self-opening dies. Solid dies are used for cutting threads that have a small pitch and diameter. Self-opening dies are designed to automatically open after being disengaged from the workpiece. Self-opening dies are often used on lathes and screw machines.

What is a die used to cut threads on?

Dies are used to make external threads on a rod, creating a threaded surface that allows a bolt to be fastened to it. The die is applied to a specific diameter of rod for the size and pitch of the threads you want to cut. An external thread (screw thread), is cut by hand with a round die that is fixed in a die stock.

What is the most common threading die?

Threading dies come in many shapes and sizes, the most common being round, square, hexagon or tubular. These can also be categorised by solid, split, and separable. Split - split dies are adjustable and used in the threading of precision fasteners as well as cleaning up and repairing external threads.

What are thread cutting dies made of?

Made from high-quality special-grade steel that is fully tempered and hardened, REMS thread-cutting dies offer exceptional durability and long life, making them a cost-effective solution for frequent use.

What is the hardness of die thread?

It is possible to die-thread metals as hard as about 36 HRC, but chasers made from the more highly alloyed grades of high-speed steel (such as M3, M4, M42, or T 15) are necessary, and chaser life between grinds is short. Metals harder than 36 HRC are usually threaded by a single-point tool or by grinding.
