Deburring Electric Metallic Tubing (EMT)

[rgsparber]

I use a cone drill rather than a stepped cutter when deburring tubing, and an internal/external deburrer on the outside.

I chose a step drill because that is what I had on hand. In hindsight, I think a cone drill is more likely to leave a sharp end if the user goes in too far.

Can you say more about the “internal/external deburrer?” Is it like the one I show on page 2?

Thanks,

Rick
