Whenever you are dealing with these types of saws, you’ll have the choice of blade size mainly a 12 inch or 10 inches are the most frequent choices. The thing to remember most about the difference between these two sizes is the weight for transporting the saw from location to location and cutting radius of any given material. The larger the blade, the more weight and harder to carry but you gain on the more substantial cuts for depth and length.

So what can you expect with this particular Dewalt radial arm saw?

This saw can be purchased with a stand in a package deal or without one in this case.

  1. Hey im not really much of a tool guy , but my father is always building something. He does a lot of work around the house and hes always complaining how his saw is crap. Hopefully when i get him this he’ll look at me like i saved his life. Thanks

    • Hi John, and if you’re looking at buying a sliding compound miter saw like this one, you’re father would be impressed with how well it works as this is the type of saw a lot of contractors use daily. There are a few major brand names that all contractors trust when purchasing different tools, and Dewalt is classified as one of the best.

  2. Very good looking site. My son-in-law is working to flip houses. I will let him know about this. One question, is this considered a radial arm saw? I thought it was a compound miter saw. But I am no expert. Thought it was a very concise review. I checked to see how it looked in my different devices. It look good in 16X9 screen, square screen, 8″ tablet horizontal & vertical, and Note 5 horizontal. For the Note 5 vertical, the first picture was to large or not large enough. The text was smashed on the right side of the picture. Hope this was a help. Dave

      There is a difference as the radial arm saws are what we all started to get use to then the sliding compound saws kept getting better in design that they are the most predominant saws on the market for most people have been using.

      Some of us older dinosaurs like to use the term radial arm saw as slang for the newer generation sliding compound miter saws. A lot of us no longer work in the shops were we would call the tools by their proper name all the time. We have red seal carpenters going around calling multi-tools as ninja’s, reciprocating saws as sawzall and the list goes on.

      Also thanks for the update on how the post was showing up on a note 5 verticle, much appreciated Dave.

  3. I own a Ryobi miter saw and it’s the best tool I’ve ever purchased, except maybe my Dewalt drill. I went Ryobi on the saw because it was somewhat cheap, but the Dewalt saws look like higher quality. How do you think Ryobi saws compare to Dewalt saws in general?

    • Ryobi makes some good tools that the average person and anyone not using them consistently will enjoy using to get their work done. Most contractors do not buy Ryobi unless they want cheap throw away tools that they will replace after they break down. Some of their tools will take the excessive usage but not all of them.

      When you purchase Dewalt and some of the other higher end brands in most cases you just bought a tool for life as far as most people’s usage. But even some of the tools created by these higher brands can still end up being garbage after some use.

      Very few companies can create every type of tool as the best, but some of them are pretty close.
