I've used tap and die sets that were tighter tolerance and made of significantly heavier materials - both the tools and holders, and the taps and dies themselves...and costing many times this product's price. This set is not meant to be a machine shop staple. I'd had an inexpensive metric set for many years but needed an SAE for a Christmas go kart 'rebuild', primarily restoring stripped or damaged threads and chasing threaded holes and nuts. These worked well for this job, though you want to take your time. Having both coarse and fine choices was a real plus.This set is sold by multiple vendors here typically varying only in the color of the case. I'm quite pleased with this version and the service they provided.
