My friend, who is a highly experienced carpenter, told me he had used several miter saws but none could compare with this model from Hitachi. I could not help it but be skeptical since I had heard similar sentiments from others concerning the power saws I had bought before that turned out to be horrible. I gathered courage and decided to go by his recommendation. Now, I can attest to the efficacy, reliability and performance of this wonderful power tool in this DEWALT DCS391B review. We will start by discussing features and specs before we look at pros and cons.

Features and Specifications of Dewalt DCS391B

This miter saw is equipped with state-of-the-art features and specifications making it ideal for a number of cutting needs. Here are the main features and specs responsible for the machine’s great performance.
  • Cordless design : This miter saw is different from others because it is cordless. While it is a common belief that corded power tools outperforms the cordless brands, the same cannot be said of this model from DCS391B. It is equipped with a strong and powerful 20V Li-ion battery. Cordless design makes it easy to handle and maneuver ensuring use even is some of the most awkward places.
  • Powerful motor : The motor of any power tool is responsible for its performance. This unit is equipped with a Powerful 460 MWO (max watts out), 5,250 RPM motor capable of delivering power as well as speed to make the most demanding cuts with ease. This means you can easily crosscut through 24s as well as 26s without having to worry about the saw slowing down on you.
  • Durability and ease of use : DEWALT DCS391B features high strength and lightweight magnesium shoe capable of providing jobsite durability for long-term cutting accuracy. I have used this miter saw for approximately two years and it still produces the same accurate cuts it was producing when it was newly bought. There are no indications that I will need to replace my saw in the near future. It is also armed with optimized rubber over-molded comfort grip that delivers optimal balance as well as control.
  • Cutting capacity : Cutting capacity is perhaps the most important feature that determines the use of a power saw. This unit is equipped with 0 degree -50 degrees bevel capacity that allows for aggressive bevel cuts for a multiple applications in woodworking as well as others. It also features 6-1/2 carbide tipped blade for cutting 2x material at 90 degrees and 45 degrees and more cuts per charge. You will agree with me that such capacity is great for all your major applications.
