So I used a Baleigh pipe coper that used an end mill. To me it took way to long to cope the pipe, had clamping issues when doing any angles 45 degrees and up and was overly expensive do these coppers have any benefit compared to a hole saw or a cut off wheel for small tubing or a die on a iron worker.
A student now but really want to weld everyday. Want to learn everything about everything.
warning!! Bad English may be in post. It's off a phone/autocorrect. I've had teachers with worse spelling!
