One of the divisions in my company is building heavy timber structures. I have bigger saws but this is the one that gets most of the use. It feels like a regular worm drive but will cut nearly 4" deep, perfect for 4"x6" and 4"x8 rafters and joinery. We even use it on the bigger timbers and just flip the timber to access the other side for the second cut. It's easier than breaking out the big saw. If there's lot's of big timbers to cut the big saw would be better but for most of our joinery and cut offs we use this one. I wish it had more power but it still does fine. A bump up in power requires 240 volts and converters, too much headache. The blade that comes with it is pretty good but put a real good carbide blade on this thing and you can do some very cool work! You won't be disappointed.
