Rated 4.8 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by Fantastic saw. I replaced a 30 year old Skil worm drive saw with this new Magnesium version. It's fantastic! The magnesium foot slides very smoothly along the work surface allowing the blade to more naturally follow a straight line. The blade spins straight and true allowing for straight, accurate cuts. As an "older" tradesmen I really appreciate the lighter weight. It's a great tool that improves my work. My only suggestion would be to add a micro adjustment to let you dial in the 90 degree position on the foot for really accurate cutting. Not sure which I love more, my dog or my saw! Don't worry she's wearing eye and ear protection. January 14, 2014
Rated 5.0 out of 5.0 by An Absolute Awesome Replacement As expected from Skil, the MagLite not only delivers clean and precise cuts on every tries, but also maintains its consistent powerful spins every times even though its reductions in weight. It is recommended by far to be an absolute replacement and/or addition to anyone. September 18, 2014
Rated 5.0 out of 5.0 by lightweight pro saw great product, good value, lightweight, highly recommended September 16, 2014
Rated 5.0 out of 5.0 by Great Saw After meticulously researching worm drives and experiencing initial use, I'm really happy with this purchase especially for the price. This design really improved upon the previous generation with weight and what I took to be performance. I tried an older SDH77 and noticed that it had a pretty good kick on start up twisting the saw to the right in a jump. I didn't feel the same kick with the trigger pull on the MAG77LT. I'll see how it does in the long term. May 13, 2014
Rated 5.0 out of 5.0 by Exactly what I was looking for. The MAG77LT Magnesium Worm Drive Skil Saw is all I expected. Light weight and durable. March 18, 2014
Rated 4.0 out of 5.0 by Great saw I have been using the mag 77 saw for twelve years its the only on i will use one thing i can't understand though is ( according to the specs) is why is the light weight saw 1.1 pounds heavier then the standard mag 77 October 11, 2013
Rated 4.0 out of 5.0 by New Lite-Weight saw Really enjoying a liter saw that cuts great , like that it cuts to 53 degrees + the built in saw hook . Not sure of the sound of the motor when winding down August 25, 2013
Rated 5.0 out of 5.0 by straight beast just got my saw yesterday. immidiate power and control. May 17, 2013
