Appropriate lubricating oil should be added to the die-cutting edge when cutting, It is to be reversed every 1/4~1/2 turn to facilitate chip discharge from the chip hole.

I bought this to repair a 3/4 x16 lefthand thread bolt that I need. Have tryed to make a bolt 6 times & every one has started right ( so I thought, I have done this many times & know how to due this with many years experence) but when you back it off it is not right it creates lop sided threads good on one side & bad on the other. You thread it into its hole it threads in as if it is bent, but it is not bent it is caused by the lopsided threads I only need this to make 1 bolt & as of my last try I am questioning what is happening As for the tap it worked fine to clean up bad threads But I do not know what it would do in making its threads in clean metal Update I tried this again on 8 bolts & it is the same story will not track right good threads on one side & minimal on the other, I would not recommend this or its handle , as a matter of fact I would like to return this as it is only going to be a paper weight around here.
