When the inquisitive engineers at Milwaukee Tools started asking professional carpenters what they wanted in a portable circular saw, they consistently heard the same three things: pure cutting power, maximum control, and all-day comfort. The result of their research went into the creation of the Milwaukee 6391-21, arguably the best-built circular saw on the market.
For starters, the 6391 has a monster 15-amp, 5,800-rpm motor that produces 3-1/4 horsepower; that's nearly as powerful as a worm-drive saw, yet this 7-1/4-inch Milwaukee model is more than one third lighter.
Look closely and you'll notice that the blade is mounted on the left side of the motor. That southpaw position gives right-handed users a much clearer view of the cutting line since they no longer have to lean over their arm to see the blade. The 10.4-pound saw's thick aluminum shoe tilts up to 50 degrees for bevel cutting.
The 6391 is also equipped with Milwaukee's exclusive Tilt-Lok handle that can be adjusted to the most comfortable cutting position: to the rear for vertical cutting, on top for horizontal cutting, or anywhere in between. The saw comes with a carbide-tipped saw blade, blade wrench, storage case and owner's manual. -- Joseph Truini

Ho Hum Saw
I have used this saw for four years working on my house. It has power. I have cut concrete, stucco, wonderboard, and lots of DF/HF and pressure treated lumber. The tilt handle thing is worthless to me--every time I adjust it, I seem to put it in the same place, where the handle is on all saws. Left cut is a poor idea for right handers. The real issue though, is that when I broke this saw and took it in for repairs, the repair cost made keeping the saw unrealistic. On a kick back I broke the gear housing. It was a careless setup on my part, but kick backs are going to happen, so there you go. Build quality on this saw is okay but not great. According to the repair folks, the problem is that quality is declining thanks to Chinese parts, but replacement part costs are higher than ever, thanks to Milwaukee. I just purchased a DeWalt 364K--it looks a little tougher. I need a sidewinder for some of my work, or I would just buy the HD77. The Milwaukee is okay, but really does not measure up against the big worm drive saws. The tool repair folks are not impressed with this saw, and they see them now and then.

Great Saw !
Tested a left handed saw - but didn't care for that manufacturer. A friend had a right-handed Milwaukee. Never bogged down. I'm a contractor and use this for cutting through wood (PT, plywood, pine 2x6, etc) also have cut through aluminum skinned panels. Like butter! I think I hear the saw laughing - looking for a challenge.
Do it right, buy it once and get on with your life.

Great saw!
No complaints at all. I love the adjustable handle angle. More than enough power for general carpentry needs. I'm not planning on using it on concrete or anything of that nature, so I can't comment on its performance in that category. The left-hand blade took some getting used to as my old saw was a cheap B&D model. Love it now.

Not bad for the price
Decent power, certainly not worm drive torque though. It does well by compensating with speed. However, the blade guard continually gets caught on the the wood being cut, which is more than annoying. I'm thinking that for $30-40 more, the Bosch Magnesium may be better. Keep in mind, this is also not made in the US or Germany like many of Mil's previous products, it's hecho en Mexico...

only two choices for left blade saw
I needed an alternative to my skil 77 wormdrive, it was either this or the Porter Cable so I went with this one. I am a pro, so I use it daily. So far it performs as expected. Mitre adjustment works well, depth adjustment works well. Havent tried the handle adjustment (and you probably never will either) The only negative seemed to be two raised indentations on the plate which needed to be filed down. Plenty of power, well balanced.
