Regrinds and bad case design

On March 03, 2017 Jim from MD wrote:

These appear to be regrinds, since they are not uniform length. The case is very badly designed, which resulted in the drills slipping out during shipping and jamming the case closed. One of the smaller drills was badly jammed in the case and was broken by my efforts to open the box. They will suit my purposes for a cheap set of numeric drills that won't be used very often, but are probably not good for someone who needs a more durable set.
