For all you tool and die makers out there... You might take note to the precision modifications made to this set of 8 to start with... 1°, 2°, 3°, 4°, 5°, 10°, 15°, and 30°.
It is now a precision 24 piece set! What I have done is burned via EDM machining (2) over sized parallels that I precision ground to an 1/8" thick pair... A pair to be used in a precision mill vise to hold your work piece at the proper angle!
This is a very unique set...one of a kind! $75 or best offer.
