The GBJ- GBJ- 4-40 UNC Tap And Die Set also appears to be of quality. But I am very concerned about ever being able to use the die, as it is of such a small diameter that I may not find a compatible stock handle.

Works great. Use safe tapping practices or you will break it.

Works ok. The die was not a standard size to fit the die holder. A adapter must be made.
