Query: Heavy duty

I bought this for a used base that came without the drill.Magnetic base drills are used to drill heavy steel when a handheld drill doesn't cut it. I use this mostly in structural steel but also in applications such as drilling truck frame rails, steel signage, guard rails, etc.I use annular cutters as opposed to solid drill bits. With hollow cutters only the outer perimeter of the drill is in contact with the steel, which reduces the horsepower needed. You can go larger than 5/8" with annular cutters. The RPMs and other specs are pretty typical.Milwaukee tools are all heavy duty and built to last. The brushes are replaceable with easy to access screw-off caps. They sell replacement parts for every part of the tool if you ever need them, which I haven't yet after paying for this tool several times over.Hope that helps.
