Title: Plenty of Saw Here Review: I took this saw out of the box, found that all the adjustments had been made perfectly at the factory, and proceeded to cut 96 linear inches of 1/8-inch plate steel and make about two dozen angle cuts across 1 1/4" x 1 1/4" angle iron. If this saw is not found on construction sites, it certainly isn't because it lacks the power. The laser has turned out to be a much bigger help than I thought it would because, since it projects well out onto the stock, it shows the slightest tendency of your hand to turn the saw. Since this can be corrected early, the cuts are straighter and the saw runs with less friction on the sides of the kerf, thus more blade speed and less chance of kickback generally. The general weight and balance of this saw, in addition the the locations and configuration of the grips, are excellent. It is a pleasure to use it. I can't imagine why I would pay more for a saw when this is available. Answer:
A:
output: Yes
