This cutter gave a very smooth cut in 1/8" aluminum panel for my project! This is a large diameter size, so be cautious of the speed. My drill press was slowed to 700 rpm's. VERY PLEACED WITH THIS PRODUCT. Thanks, from Indianapolis.

Bought this for working with heavy steel, I have cut 3 holes through 1' mild steel and as many through 1/2'. It took some tuning to get the drill press dialed in, but at the proper speed and with some lubricant it does a nice job. On pieces thicker than 1/2 it works best to flip the metal over halfway through the cut to finish from the other side. Looks pretty much new after the 6 holes I've used it for, looking forward to using it on the next job.
