Does this saw come with a carrying case?

what is so special about a worm drive circular saw

Asked by: Bones
A lot more power than a sidewinder. Blade is on the left, which affords better cut visibility. Weight of the saw is beneficial depending on cut position - will fall through the cut when cutting out of your hand.

How do I change oil I know where the fill cap is but I don't see where I can drain the oil

I already have the Milwaukee oil for the saw
Asked by: Edwin202
Hello Edwin202, I’m Chris from the Home Depot’s how-to Community. Thank you for your question. Unlike a car, this saw does not require regular oil changes. However, you may need to top off the oil level from time to time. It should be many years before major maintenance like replacing brushes and motor bearing lubrication is needed. I hope this helps, Chris. .

15 Amp 7-1/4 in. Worm Drive Circular Saw is rated 4.8 out of 5 by 17.
Rated 5 out of 5 by from Great Saw, It made me remember driving my first new Cadillac On the heavy side but making up for it ease of uses, I've had many circular saws but this is my first worm drive. What was I thinking

Rated 4 out of 5 by from Excellent Saw Nicely designed saw with plenty of power. Cuts straight. Depth and angle adjustments are easy to make and the scales are marked which is a real convenience. Definitely on the heavy side but it is well balanced and easy to control. The one design feature I don't care for is the Allen Wrench used to remove the blade nut. I am worried that the bolt will strip out over time. I think a conventional wrench would have been a better choice. My only disappointment is the lack of a storage case. If I leave this in the back of my truck it will take a beating.

Rated 4 out of 5 by from Nice Saw I am impressed by the power of the saw. The saw is amazingly quiet. I like the blade being on the left side for seeing what you are cutting. It does take a few cuts to get used to the blade position and weight. overall it seems to be a quality tool. I was disappointed to see a made in china tag on a electric Milwaukee tool. The saw base is made of a composite material, it works great now only time will tell. For the price you can't beat it, I would have paid double for one made in America, like the older Milwaukee Worm drive saws, made to last a lifetime. Just my opinion for whatever it is worth.

Rated 5 out of 5 by from great saw I really like this saw. The blade is on the left side which makes watching your line much easier. It turns at a slower RPM than direct drive saws, but it has much better torque and an added bonus is that it is MUCH quieter. It is heavy though, so overhead cuts would be challenging. When cutting sheets of plywood the saw cuts straight with little effort and the large platform keeps the saw stable. There's also a hook built onto the body for hanging it up for storage or to keep it out of the way. I'm glad I bought it and I think it will be the last saw I'll need to buy because of the build quality.

Rated 5 out of 5 by from Great saw for many uses This is such a great saw for pretty much any job due to its durability, ease of use, and power. I really liked the fact that it is much quieter than other worm drives that I have used. The first time I used it, the blade flew through the wood like a hot knife through butter. All in all, this saw should last me for a long time.

Rated 5 out of 5 by from beats the best I bought it to cut through 1 inch stucco I sunk it all the way through and it cuts great it is still very heavy but more comfortable and way more powerful than the dewalts and rigid that I bought the same day it cut 190 square of stucco and laugh and is still going strong

Rated 4 out of 5 by from You will get work done with this saw My old Black and Decker worm-drive (3051) and Rockwell worm-drive (568) had just died on me. No parts were available, Rockwell is long gone, and Black and Decker used to be great but now they're just home owner junk. I was using a Dewalt DWS535 worm-drive saw about a year ago and the darned thing caught fire on me while making non-through rips in hard beams. I did not have it for 5 years; I only had it for 10 minutes. I vowed to never buy another one of their products again after that. So I looked around and tried many worm-drive saws and settled on this one. WHAT A DIFFERENCE. This saw does what it's asked to do with no complaints. The blade change is pretty fool-proof and the bevel adjustment is smooth, quick, and easy. This saw has a 3.3-horsepower motor is very very smooth and never bogged down unless I forced it. It's everything that a carpenter could ask for and it has a wonderfully long cord to boot. My only complaints are the weight (15.1 pounds-force) and the blade changing. Compared to an allen key, a hex wrench is less likely to slip and cause injuries. Also I have to lift the guard when doing bevels steeper than 15 degrees or else the guard will snag when I cut. I am also very disappointed to see a Made in China tag on a Milwaukee product. But other than that this saw is great. The true test will be its longevity but from the workout I have given it so far. I am confident that this is one rugged and reliable tool. I currently have three worm-drive saws: this one, a Skilsaw SPT77WM, and a Makita 5377MG. Good bye Dewalt, no more junk for me.
