Review on HQMaster Straight Milling Cutting Tungsten by Dang Esq

It was pretty hard to tell from the seller's photos that this is not a universal bit, but upon inspection (see attached photo) it is clear that these bits are center cut! This makes them much less useful for amateur or professional CNC users unless you are very careful to reduce the plunge speed as they have a hard time moving straight down (vs sideways). This is a somewhat critical flaw with these bits, which unfortunately renders them unsuitable for general use.
