Die Stock

Die stock is expressed as the type of component which is utilized for fitting purposes while creating or shaping uniform threads on tubes, pipes, or screws. The die stock (die handle) has three screws around the adjustable part of a particular machine that helps to locate the die. Also, die stock can endure on a variety of hex and split adjustable dies of several dimensions. One of the primary reasons for using die stock in industries is because die stock can be operated by hands. Commonly, it is made up of high carbon steel.
