In the demolition business copper is your bread and butter. Helps cover other costs involved. Large copper feeder cables are rough and bulky to strip until I tried this product. Sends 1" cable screaming through and all the way down to 1/4". Built well. Only recommendation is to possibly have a few step ups built in for the cutter wheel. Something like a bolt on ledge that keeps it secure. I noticed that the wheel can retract upward quite a bit but with the hole jig stuck on the bottom it prevents other smaller and larger thickness. I would pay a little extra for this mod.Thanks.
