Hello,

If I cut a threaded rod in the middle using a wire cutters or pliers I cannot use that end any more because the thread is ruined on both ends of the cut.
How do you do it?

Thanks
Alex

put a nut on it, thread it where you want to cut, then cut, now back the nut off of it, it trues the threads. I use a dremel with cut off disc.

Use a Dremel cut off wheel and then taper the circumference slightly. Dan.

Thanks guys didnt think about that, my head is working in the pre dremel era though i have one.

I use the dremmel too but yesterday I cut a couple of rods with wire cutter and polish the ends with the dremmel: it worked fine too.

I was taught, many years ago, to use a fine triangular file. Just support your threaded rod in some 'soft jaws', and file around the cut line. After you have cut around and to a depth of about 1/3 total of the rods diameter,(3 or 4 passes), the rod will usually snap off at the cut line, with a bit of a bend.
This method leaves a bit of a bevel, (good for starting threads), with a circular, grainey tip, which be dressed off with a fine flat file, to the desired depth of bevel.
This is the method I use, as well, for cutting metal pipe and tube, regardless of diameter.
I hope this is of some help.

I just cut it and then touch up the end buy holding the rod against a belt sander at an approximate 60° angle while spinning the rod.

I cut my rods with tin snips, nice and fast. For thick rods I use the dremels as well. Then I take the burr off by rotating it against my bench mounted grinder, take like 5 sec.

I have quite a few threading dies. I first run a die on the rod and then cut the rod with a Dremel cutoff. I then file off the burrs and round it a bit and then work the die over the cut end. Works every time.

That's how I do it too!

I have a wire-stripper that has built-in dies to cut screws.

What Walt says. You can get a wire tool with sections to strip, cut, crimp, and cut small bolts or threaded rod. They have one side with different size threads. The other side is large enough for the screw to pass through. Thread it to the correct length, make your cut, then when you back the cut screw out the built in die will clean up the threads. Has both standard and metric sizes. Less than $20.

Me too. sometimes I use a bench grinder.

Most threaded rod is super soft and can be fixed up with a flat file very easily.

I wouldn't use tin snips since the edged can get nicked easily screwing them up for fine cutting on sheet metal later.

Thanks a lot guys answered my question.

This works for weak screws (softer metal) but does not work well for some of the stronger ones, at least not more than once as it destroys the wire stripper. The Dremmel and cutoff wheel is a much better option for case hardened screws.
