How hard you can push it depends on what type of aluminum alloy, the thickness, system stiffness, chip evacuation, and lubricant... best judged by feel, as you mention, especially with a hand tool. WD40 will help keep the chips moving out of the gullet and from sticking to the cutting edges, this is pretty critical with a circular saw. I think you will have good results with some lube and steady feed. Good luck, safe cutting! | |

In fact, sometimes when I pushed harder, it seemed the aluminum provided less resistance. One lives and one learns. | |
