    • All the power you ever need in a 16-5/16 inch saw
What a beast of a saw! I had my doubts that it would have enough motor wattage to push that 16-5/16 inch blade through the full cutting depth but man of man did it excel. I ripped wet 8x8’s and it never bogged down, unlike my 3hp bandsaw. Just needed a flip and second pass. The blade is scary sharp and with that torque from the worm drive chewed through everything without complaint. Also, I was hesitant about kickback from such a large circular saw but the low rpm and sturdy frame/handles make it easy to control. My only minor criticism is that the spring tension on the guard is a little high for my taste, but not impossible to overcome. The plastic dock is nice for storage and transport and was more stout than expected. Overall, so happy with my purchase. This is a must have for 6x and larger timber work! Skip the higher priced makita, you will be pleased you did. ... show more

    • Accurate, powerful, handleable even for an old guy
This review is for the SKIL 16-5/16 In. Magnesium Worm Drive Skilsaw. To be clear, I am a somewhat advanced user of home renovation tools, though I'm over 60 years old. I have to admit that buying the saw was somewhat daunting for me, both because of the price and I was somewhat reluctant to handle such a big beast. However, I have now used the saw to do some very heavy duty cutting, starting with cutting through 6" slabs of concrete, using a GRAFF 16" Laser Welded Diamond Blade. Typically, in 5 to 6 passes through very dense concrete, this saw was able to tackle the job without a single foul or kickback. The cuts I was making were through stretches of concrete from 2 ft to 18 ft in length. The saw does spin at a lower RPM than it's smaller siblings and does lose some RPM as it cuts dense concrete, however, the worm drive is very capable at maintaining power all the way through the job, given occasional breaks to allow the blade to spin up. The lesser RPM than it's smaller sibling (the 7-1/4" worm drive) is somewhat deceptive, as the actual speed that the teeth move at is somewhat similar to that of a smaller saw. I find the saw remarkably handleable and can even drop it into a concrete surface with a plunge cut maintaining terrific control; in the many times I've done this, I've not had a single kickback. I've also used the saw for cutting 6"x6" timbers with the supplied skill saw blade and have had great success with handling this very large worm drive saw. Moreover, the accuracy of the angle mechanism from base to blade appears to be extremely good and does not require adjustment with a square, which makes cuts through thick wood or other material more accurate. The magnesium alloy body, platform, and casing makes this saw both lighter and incredibly durable. The saw is not as heavy as it's Makita competition, which I've used, delivers more consistent power by its worm drive mechanism versus the sidewinder, spins at a higher RPM, and is quieter than the Makita as well as its Skilsaw 7-1/4 inch worm drive sibling. One of the features that makes this saw so easy to handle is the placement of the auxiliary handle for added control. The saw also has an excellent stand that comes with it, which makes it easy to store and also easy to change the blade. My single criticism of the saw is that the blade guard is a bit too stiff and can impede moving the saw fully into a cut. Perhaps this will loosen some with time but I do think that Skilsaw should consider putting in a lighter spring mechanism. This would also make retracting the blade guard for a plunge cut somewhat easier. Overall, however, I am very pleased with this saw, which has by its excellent function helped me overcome any reservations that I may have had about purchasing it. Overall, it has saved me hours of intensely unpleasant work, made the work more accurate, and has also saved me the cost of repeated rentals of concrete saws at my local home supply stores! For the money, and in comparison with its competitors, this saw is definitely a cut above, no pun intended. ... show more

    • Big saw for a big job
This saw is awesome! It cuts steel like butter. It’s easy to use and cuts a straight line every time. It’s a little heavy, but it’s built for the big jobs. Be sure to wear your hearing protection!

    • This thing is a monster. Great as a straight-line rip saw
Review Image by Mark
This thing is great. The stand/base it comes with is very handy and keeps the saw in good condition. Its not too heavy being such a large saw. I'm only 5'7 and can handle it easily. It walks through the wood when crosscutting. I straight lined 400bft of 10/4 black ash no problem. It runs a little slower on the rips with the standard blade, I may eventually get a ripping blade just to keep the saw happy. That being said the one it comes with is a nice combo blade. Min depth of cut is a little under 2.5 in so its not possible to do two passes on anything thiner. ... show more

    • Great value, lots of power
I bought this saw to replace a Makita beam saw that I picked up used. It is a big improvement over the Makita, mostly because of the design of the shoe. I could never get the Makita to cut reliably square because the shoe was flimsy stamped metal and would flex. The shoe on the Skilsaw is constructed rock solid and will keep the blade square in the cut every time. It is also noticeably lighter than the Makita. I haven’t had any of the performance issues that other people mention - I bury it in tough white oak at full depth and it cuts fine. That said I’m keeping within 1/32” of my cut line so I’m not pushing it super fast. Also I really appreciate the design of the molded plastic saw holder, which has a low center of gravity (less likely to tip over in transit) and bails to lock the saw in place. ... show more

    • Great Saw
Great saw worked perfect out of the box cut square. It cuts through pt 6x6 like butter. Need to make sure that what ever you are cutting should be clamped down. For the size of the saw the power it had felt accurate and balanced.

    • Nice saw
Very happy with this purchase, I've owned the Makita version of this same saw and find this one to be a much better built machine. Its very smooth and the aluminum base is strong and well built. The worm drive appears to be the same size as a standard 7 1/4" worm drive but they power is about the same as the Makita 16". I've been using this to cut 6x12 rough green hemlock, when the blade is buried it will crosscut fine but struggles a bit ripping a full 6" and angle cuts bog it down somewhat. If you are using dry timbers I don't think it would be a problem but the wet wood puts a lot of friction on the blade. I did break the shoe bolt I guess by overtightening but it was an easy fix with a new set screw. Despite this I m very pleased. ... show more
