In addition to the sheer brawn, Bosch really has finessed this machine, and the beauty is in the details. Our favorite feature is the Direct Connect system: The tool itself has no power cord, just a receptacle for your extension cord and a super locking mechanism to keep the cord connected. It's so secure that you can actually lower the tool off scaffolding to the ground by the cord. Next time you accidentally cut the cord, it won't put the whole saw out of commission: Just grab another extension cord. Storage is a breeze, too, because there's no integrated cord to tangle with. We love the left-side blade for unmatched line of sight, the worm drive gear train will hold up for years under the toughest conditions. Changing depths and bevels are fast, easy, single-lever operations, and you'll like the lower guard design when slicing off a narrow piece because it does not snag. If we had to name a down side, the saw is a bit heavy, but that's a negligible detail in a piece of machinery like this.--Kris Jensen-Van Heste

This review is from: Bosch 1677MD 15 Amp 7-1/4-Inch Wormdrive Construction Saw with Direct Connect (Tools & Home Improvement)
This is a great construction saw, simple, powerful, tracks well, durable. This saw tracks effortlessly through all plywood, 2x4, 2x6, 8x,PT, engineered lumber, whatever you throw at it. If you are on the fence about buying this saw because of the weight, don't be, the weight works to your advantage. The weight and in-line motor design of worm-drive saws are easier to use and because of this, this saw tracks so well on long free hand cuts through all plywood. With a few uses you'll be cutting perfectly on the line & consistently on the longest runs.
Sidewinders do not track even half as well, take it from somebody who until recently, used only sidewinders. Sidewinders kickback way more frequently than worm-drive saws do, because of the weight (and other design features). If you are smart about how you set up your cuts, The Bosch worm-drive will not kick back on you. Also, it has a vari-torque clutch, which also helps prevent kick backs as well. Basically it is a fancy name for the arbor washer (blade washer) that is designed to slip when, and if the saw blade binds, so the result is the arbor keeps spinning, but the blade does not. Remember not to over tighten this washer, or you will over-ride this feature. Once arbor bolt is finger tight, use supplied wrench and tighten 1/8 turn past finger tight, if blade spins too frequently (very rare) just tighten a nudge more, if kicks-back, loosen a bit, very easy and it works well (fully adjustable to different materials).
The direct connect feature is the only one if it's kind, and works well. Basically it has no power cord, you plug your extension cord right in the handle. Easy storage, and no more tying together multiple extension cords. It has two spring tabs that securely keep the cord end in place in the handle and has a smart strain relief design. You pre half-loop the last foot of your extension cord, feed the loop through the oval cut-out on the bottom of handle and snap the half-loop into place on the hooked tab and run the female end into the handle of the saw. The only downside is you have to use factory made extension cords because the spring tabs are very tight and no clearance for custom made plug ends. I have several 10/3, 12/3 extension cords I made up from bulk spool cord and none of the ends fit into the handle. I managed to customize one 10/3 cord to work, but it was a pain. The only issue I see happening is the spring tabs could wear out, and if you repeatedly stuff a larger plug end in; it seems to split the molded handle a bit at the seam.
Depth of cut seems to be accurate on the preset marking, but the lever and armiture needs a little grease here and there for smoother operation.
Bevel is 0-50 with a detent a 45 and a spring tab you press to go past 45. There is a set screw on the shoe for adjustment, and mine needed a slight tweeking. This saw cuts about the same depth as all the other 7-1/4" wormdrives do at 0, 45, 50 so on.
The saw has magnesium construction for lighter weight and is about 14lbs and change. The shoe is magnesium waffle design and is very ridgid construction. The construction of the lever locks, shoe pivots, bevel pivot, swing arm etc is very heavy duty with no slop, it feels very solid and well built. The motor housing and motor vents etc. are basically identical to the Skil (Bosch bought Skil and make them both). This saw runs very smooth and is quiet (runs at 4,400 RPM, sidewinder's scream at 5,800 RPM) and is very well balanced for one or two handed cutting. You can change the brushes very easily on both the Bosch and skil, so basic up-keep is easy. You have to change the oil on worm-drive saws, but wormdrive's will out last sidewinder's by 2x's or more easily and changing the oil takes a few min max. My dad still has his old Skil and it works fine, his old sidewinder is totally shot, it's useless and dangerous because the shoe is so badly bent out of square. Wormdrives can last a lifetime and can take abuse, thats basically why I bought one after years of using sidewinders, and will never go back (except for maybe Hardie plank).
The Bosch is a great saw, heavy duty, easy to use and very powerful, won't bog down. Mine was basically square when I bought it and only gave it a slight tweek to make it perfect (you can check alignment with try square on shoe to blade) it was so close, but I tweeked it anyway to get it perfect. I read a few reviews where some were out of alignement badly, but there is a set screw the bring it into square and easily done & I highly doubt the shoe was bent, this thing is built like a tank. I got lucky and found one made in the U.S., I think the Bosch and Skil are both made in China now, but that should not stop you from picking one up, you'll never use a sidewinder again.
