Die stocks – or die holders – are tubular parts that are used for fitting and turning dies, a tool used to cut or shape materials. Die stocks are often used for cutting and threading (sealing) metal objects like pipes.
What is a die stock?
Die stocks hold a range of different sizes of hex and split-adjustable dies. They’re made from solid materials to ensure a long product life and have knurled handles for extra grip.
Die stocks usually have three screws near the spindle-facing side of the tailstock (the adjustable part of a lathe, rotating tool) to position the die, and a cylindrical disc containing the cutting tool. Holes cut symmetrically around the central thread cutting tool are for chips of metal or other material.
Why use a die stock?
The three screw design easily locks a die into position and maintains alignment for accurate threading and clean, straight threads. In turn, this means dies can be used to create new threads or repair worn and damaged threads.
