After too many years of unsatisfactory results with yellow and gray sidewinder circular saws, I decided I deserved a good worm drive saw. All the reviews of the Skilsaw were pretty positive, and I liked the idea that Bosch had continued making such an old design with limited changes. First use was a revelation, As many have noted, the saw tracks very well, and following a line is no longer a WAG as with a sidewinder. Some other handy features are the depth markings on the shoe adjuster, the folding hanger hook, and even the sole plate has been thoughtfully dimensioned to 1 1/2" on one side of the blade and 3 1/2" on the other. Can you say, "Standard 2 x 4 size"?
In spite of light alloy usage, this a heavy machine. I suppose the weight is something of an advantage as the power output is substantial. It amazes me to see videos of pros using this tool with one hand on framing jobs at scary heights. All in all, a good product, good enough that finding one on eBay for much below market doesn't happen very often.

The manufacture is farmed out to a Chinese subcontractor, who then subs out various parts to varying subs and assembles it. the result is a saw of variable quality and usefulness. I have had a US version forever, and bought a new one because I had a helper on a big project, and I wanted him to do as well with his saw as I do with mine. I knew it was pretty poor when I held it in my hand as I released the trigger and felt the roughness as it wound down. On a US saw, that would be a sign to take it in and get the bearings replaced. This new saw started out life with bad bearings. I took it back to the store and the guy shrugged, saying they are all like that. He let me pick my replacement, and some were rough, a few were smoother, so I took one of them.

My helper and I both soon saw that the base plate was a hodgepodge of problems. The parts seemed to be just poor copies of the original. hv Same as others have reported here. Also, the motor smells like it is running hot.I expect it to fail soon, as that smell always foretells a burned out motor.

I returned it for a refund, and bought a Harbor freight cheapie as a 2nd saw. It is no prize, but it is cheap, and I paid extra for the 2 yr replacement warranty.

Too bad. The DeWalt 77 used to be the best saw out there.

I finally acquired a shelf demo that was USA made and am happy as a clam at high tide. It feels like a Swiss watch compared to my elderly 77, and made the Chinese 77 feel like a cement mixer full of rocks.

This is the son of the saw that built America, aka the Skilsaw. Notice that it's Skil and not Skill, and Happyness vs. Happiness. Today this saw has more variants than a 60's Corvette. The most recent upgrade includes a magnesium housing, aluminum foot, higher temperature motor wiring, and 2 more amps of current usage (hopefully translating into more power). Like many of you who don't own a worm drive Skilsaw, I was confused and am still confused about which one to buy. When in doubt, buy the most expensive model in the line. Ha ha. There are variants built out of steel, those with a removal cord, and even one that sits on wheels. This is not a joke. I saw one with an accessory plate that had 4 wheels on it. I ordered this just to have a saw that could ride atop concrete. The accessory was priced at $62, and is not offered by Amazon yet. Stay tuned. Anyway, the version of the SHD77M you should buy is the SHD77M-22. That version has a cloth bag. Now let's get to my evaluation of the saw. Power corrupts absolutely. There is no substitute for power. Once you get used to power, you don't want to go back. If you are cutting moist 2 x 12's or are building a deck with Ipe or Tiger Deck materials, a smooth and powerful saw is your only ticket. Another thing this saw does is score concrete. I use this term lightly because a 1/4" depth of cut is almost like scoring the material. That's Skil's recommendation, but you might want to plunge 1/2" with the right blade. Make sure it can take the rpm of this saw. They also recommend successive cuts, which I like to do just to keep the heat down. Okay, now that I have described the power and smooth sound you get out of this saw, let me get down to precision. First, the included carbide blade is disposable. The tips, when viewed closely, have chips on the side.Read more ›

My new Skil SHD77M arrived. I heard that there was a problem of the base plate not being flat, but assumed Skil had fixed that. Mine is way out of flat! The whole saw rocks as you place it on the work piece. So, back she goes. What a pain.

this is the classic framing saw, I wanted a high quality handheld circular saw and based on what I saw contractors using I figured if I got this one I couldn't go wrong. Well, I sort of did. I bought this not from Amazon but from CPO Skil as a recon; the saw is great. BUT. the foot when set at the 0 degree detent is not exactly 90 degrees to the blade, and there's no adjustment. The Bosch 1677M which is the new and updated version of this same saw includes among other improvements a foot assembly with a fine tuning adjustment for just this issue. The good news for me is that I can buy the Bosch replacement foot for less than the cost difference between what I paid for my recon Skil and a new Bosch saw, and the part numbers for the two case pieces are identical so it should be compatible; however, if buying new, I would highly recommend going with the Bosch 1677M just for that one refinement alone. Yes I know that it is a framing saw but there's no reason that a tool of this quality AND PRICE shouldn't be able to be set up to produce exactly square cuts without fiddling around with fine setup - if there's a 0 degree detent, it should be able to be adjusted so that the detent is at zero degrees plus or minus a fraction of a degree. The Skil is not capable of this out of the box; the Bosch is. 'nuff said.

This isn't a *bad* saw... but the Bosch is a refinement of this same design (Bosch owns the Skil name now. I'm not sure why there's differences between the Bosch saw and the Skil - you'd think that they would have discontinued one, and/or applied improvements equally to both. But they didn't, and the Bosch in my opinion is the superior product, even taking into account that the Bosch is typically slightly more expensive most places that you look.)
