Cutting steel with a circular saw and angle grinder to building my steel deck was easy enough. I could have used:
1. Angle grinder, or hand grinder, is a great metal cutting tool. It is good to work on small areas, but not for fine or finished cuts.
2. Reciprocating saw, or oscillating saw, works well, but doesn’t do very smooth cuts.
3. Circular saw saws are the most commonly used power tools today, though it can’t cut curves.
4. Hole saws connect to a drill, and cuts a perfect circle.
