For this post, I have put together a collection of the best tap and die sets currently available.
UPDATED: August 16, 2019.
These simple yet versatile tools are used to create the common nut and bolt pair. The tap is used to cut the inner thread of the nut and the die is used to cut the outer thread of the bolt.
Using the included T-Handle, threads are formed by cutting (tapping) into the hole that forms the bolt and cutting (threading) the round steel stock for the bolt. Typically, to reduce movement while working, the pieces are held securely in place by using a bench vise.
The following tap and die sets use the latest innovative components to meet your needs and help to ensure you do your best work.
