>My tap and die set is total shit

I have the same $15 Harbor Freight tap and die set.
To say its shit is an understatement.

I needed to tap a hole in some mild 1/4" scrap steel. I actually thought of this thread and decided to try out the HF set, I have never actually used it for anything because I have a big collection of good taps and dies already.

>drill #7 size hole
>start trying to tap with 1/4-20
>just spins and spins and wont start

It just reamed out half of the fucking hole and never did start cutting threads.
I grabbed a cheap crappy Century carbon steel 1/4 tap and it started with the first turn and cut the rest of the hole quickly.

The 1/4 HF was a 3 fluter (most other taps are 4 in the kit). It looked pretty shit so I decided to try out the 5/16-18
Same thing, it just reamed out the hole and wouldnt start cutting.

Its actually baffling how horrible they performed.

There is a sucker born every minute. Just because you impressed your mom by downloading Robinhood doesnt mean you are going to impress anyone else.
