Not sure if it would help but it was a lot cheaper than alternatives. After pre-drilling 1/4" and then 1/2", I drilled two 2" x 2" x 1/4" steel wall tubing using plenty of wax lube and at the lowest speed of the drill press. was installed in the hole , the quality of the hole was good and I could probably use the drill again for additional holes.
