When you think about it, a reamer *can't* work properly with no
taper--all
you have to do here is consider in theory what would happen if the
taper
were reversed....tapered hole and entire flank would drag........

Thinking about it isn't your strong point then it seems. How do you
suppose
reamers that are actually designed to produce tapers like taper pin
reamers
and Morse taper reamers work if every reamer needs to have a back taper?
Do
you even know what the back taper on a chucking reamer is there for or
how
the amount of taper is determined?


Your obviously a freaking moron......

That's a *tapered* reamer, and its *designed* to produce a *tapered*
hole.....and it has little to nothing in similarity to a chucking reamer
in
operation except they both enlarge holes.

No use trying to wriggle out of it now. You were quite clear that every
reamer 'had' to have a back taper or the 'entire flank would drag'. Even
hand reamers cut on a fair length of lead-in and socket reamers cut on the
whole flute. No 'dragging' involved apart from the slow and painful process
of trying to drag some sense out of you. Time to pop you in the killfile I
think because there are better things to spend time on than arguing with a
numpty who A) seems to know very little and B) has actually admitted that
harassing people rather than helping the OP is one of his aims.

Plonk.
