Hozan pedal taps acts like much more of a thread former than a
cutting tap. (pretty worthless for cutting new threads) Very long,
with a gradual taper running the whole length. A better choice than
the Parks for cleaning up damaged threads. Would be the 1st I'd try
for French-to-English

I haven't seen the Eldis available for quite a while. UBS has the Vars but wholesale price is within a buck or so of the Parks. They have even less of a taper and the threaded section less than 1/2 as long as the Parks.
BTW the majority of my business is shortening cranks by drilling and tapping new holes. 150-200 sets a year. The Parks are good for at least 100 sets, cutting new threads in 6000 series aluminum. Probably good for a lot more but my shoulders are so bad that I replace them as soon as I notice increased resistance at the tap handles.
