Yes my primary use is copper piping
the blade is not replaceable
Yes, it should move freely.
Can Milwaukee Electric please explain how to replace the blade? I broke mine off and cannot figure out how to replace it. Thanks
Yes, as aluminum is soft like copper it works just as well
Yes it might be a tight squeez tho
The blades are replaceable, I would recommend purchasing the Milwaukee replacements as they may differ from other brands
available at Home Depot and most hardware stores
