For a cheap specialty tap I was surprised how well it worked. Probably wouldn't want to do production work with it but for a small project this worked very well.

Drilled the 33/64th hole as required but this thing would not even start to cut. Yes, left hand thread but it just wouldn't bite. Drilled the start of the hole slightly larger and still nothing! Getting tired of the garbage products available these days.
