The reamer will be dull soon. It shurely happens after ~ 3 reverse turns due to friction of metal chips (back angle of reamer's blade does not cut).
It is very difficult to physically destroy an reamer by such way but there are 3 problems:
1. Dull reamer will "scrap" instead of "cut". Surface will be more rough and hole will be more inaccurate (bad roundness).
2. You HAVE to re-gring dull reamer to sharp its blades.
3. Re-grinded reamer will have smaller diameter - reamer will be inaccurate and inappropriate soon.
Example:
Typical diameter of new (metric) 10H8(+0,022) reamer is 10(+0,01;+0,015).
Diameter of re-grinded reamer will be 10(+0,005;+0,01). After next re-grinding reamer will be 10+0,005 , next time 9,995+0,005, next time 9,99+0,005, 9,985+0,005 and so on.
Reamer marked 10H8 with outer diameter 9,99+0,005 is inappropriate(9,995 is _smaller_ than 10. IT IS VERY BAD due to possible fit error).

What is the Difference between a reamer and a drill bit?
A reamer generally can't start a hole, only enlarge one already made.
What does reamed mean?
to enlarge to desired size (a previously bored hole) by means of a reamer.

What happens when the fan rotates backwards?
Air moves in opposite direction and if it's on a car-it will overheat
What happens when a fly wheel is put on backwards?
It rotates the other way. Yeah, right. You CANNOT put a flywheel on backwards. It's not physically possible to mate the flywheel with the crankshaft unless it is the correct direction.
Does Neptune have retrograde rotation?
yes it dose it rotates backwards
What planet rotates backwards compared to earth?
I think venus
Is the Earth spinning backwards?
No, the Earth is not spinning backwards. It rotates on its axis in a consistent direction, which causes day and night.
Is there anything that makes Venus different from the other planets?
It rotates backwards.
What part of the boat rotates to power the boat forward or backwards?
propeller
Why is the helix angle of a reamer negative?
The helix angle of reamer is negative because to make the reamer more regid so that the reamer can withstand the vibration during reaming
What is the melting point for reamer?
A reamer is a tool, not a material. The melting point would depend on what material the reamer is made of.
What is characteristic of Uranus?
Uranus has the coldest atmosphere at -224C on average. Something that is unique about Uranus is that it has 22 moons. Also, it rotates on its side instead of upright.There are two odd things about the rotation of Uranus. Firstly it is tilted at 98o or 8o past horizontal (it rotates on its side). It also rotates backwards compared to the other planets except for Venus that also rotates backwards.

When was Robert Reamer born?
Robert Reamer was born in 1873.
