When using a dye, should you reverse to dislodge the chips?
 

This is not a big deal, but...

I just noticed a "Gearwrench" tap and die set that apparently includes a
ratcheting handle for cutting threads on a bolt. Looked good, would be
better than releasing and re-gripping the handle, but maybe not if you
are supposed to reverse direction in order to break off the chips?

Is there a general consensus for the usual situation, about reversing
direction to break off the chips when cutting threads on a bolt?

Thanks.

I guess there are higher class ways to cut threads on a bolt than a
typical tap and die set, but indulge me.

Stupidity kills. But not nearly often enough.

Generally yes, you do need to reverse every now and then to break the
chips. The small releifs in a die fill up fast, once full the die
cannot cut cleanly. I've never seen a spiral fluted die? I wonder if
its even been tried?
