Review on HHIP 1015 0750 Double Boring Degree by Brett Gilbert

I bought a set of 5 pieces 1/4" - 3/4" (1001-0008). My boring bars have nice square holes for holding cutting tools. This is interesting as other reviews from a few months ago and product photos show a large hole with sewn corners. The product documentation (HHIP.com) states that 1/4" and 3/8" shots use a round nozzle, as noted in a recent review. But I have square holes. Also the 1/4" boring bar has a very thin wall next to the square hole. I haven't used them yet but they are straight and should work fine.
