Forgot to debur conduit

In my ignorance, I forgot to debur a 3' piece of 1/2" emt I used to extend a circuit. After cutting with a hacksaw (one side of the pipe is the cut from the factory) I didnt think to much and only gave it a twist or two in a 4-1 battery brush and put it into service.

Is that bad practice?

I was kind of thinking in the back of my head that the set screw connector covers the cut end of the pipe... but thats not the case right?

Yeah, you should debur with a proper tool, not so much to allow fitment to the couplings but to keep the burrs from chafing the wires when you start pulling them, since the burrs are pointed in and not out.

Would you redo it if you were me?
Does the cut end from the factory need deburring?

Its 3 feet of wire. straight run, no bends. I pushed the wires in by hand and they slid right in. Boxes (screwed into masonary) and set screw connectors were in place. I sure hate to break it all down for this.

Probably not. If you got the wires in without chafing them, and you chased it first with a wire brush, you may have dodged the bullet. On a commercial jobsite, you would be redoing it, though, along with 3 before that junction just to make sure you didn't do it in other places

Does the factory cut side need deburring as well?

I used a hacksaw, but on a basic tubing cutter, is the triangular metal piece that folds into the handle a deburrer?

Would a cheap deburring tool with the small blade you use on copper suffice for emt?

Many in the trade just use the nose of the pliers or the handles of channel lock pliers on larger sizes. You just need to knock down any sharp edges.

I always do both ends of the conduit, factory or not.
