Summary: I've owned two of these--made the mistake of selling my first one thinking I would never need one again. Naturally, when I once again needed a steel-cutting chop saw I considered this model. Amazon, as usual has the best price. This is no rookie light-weight stamped-steel base saw--it has a very heavy cast iron base which keeps it from walking on the bench. The quick-release clamp works well and even adjusts for angle cuts.
Summary: I have had this saw for about 5 months when I noticed a small crack on the left side of the arm (I have used 3 blades). I contacted Milwaukee, of course you need to send it in for evaluation to see if it would fall under the warranty. I sent them some very clear pictures of the crack, explained it had not been moved since I took it out of the box and put it in the bench.
Summary: The stamped steel back half of the vise is not true vertical, so it's okay for 90° cuts. I needed 45° cuts on square stock and the cuts were oblique. I returned it and got the 6180-20 for $40 more. The base is cast aluminum and solid, but the vise is cast iron and therefore machined and square. The motor has more power, too, and the handle is a better orientation. It's worth the extra. Yes, of course it's made in China. Isn't everything?
Summary: I have had my saw for a couple years now and have not had a problem. Seems other people have had switch problems but mine has worked fine and I have gone through around 30 abrasive wheels. I was disapointed to find that milwaukee just stamped there name on a foriegn tool. This tool is not the quality I would expect from milwaukee, I think it is as good or better than any of the other entry level abrasive saws.
Summary: I bought this chop saw having been a longtime customer of Milwaukee tools. The saw works well, but does not have the "fit and finish" that most loyal Milwaukee customers have come to expect. Careful inspection of the tool shows a "Made in Taiwan" label, which explains the relatively "cheap" appearance. The saw looks like a red off brand in construction with a cheap "Milwaukee" logo sticker on the blade guard..
Summary: I love this machine. I can't believe I wasted so many years with a hacksaw. Only had it a week, but so far it has worked perfectly on unistrut, rebar, steel tube, heavy-wall aluminum tube, and steel plate. I'm totally satisfied with it.
Summary: After shopping around, this machine is clearly built better than the rest. Others had cast aluminum or stamped beds, the Milwaukee is cast iron. My first job was cutting 10 foot sections of 3/16"x3" angle iron, the tool held them perfectly aligned and cut them smoothly in about 10 seconds. No wobble or runout. Also have cut some bricks with masonry blade with excellent results. Great tool, not much more $, why buy anything else.
