Blade size decides how deep can the wood log be cut and in different positions how well the product can protrude through the wood logs. Sometimes it does lead to confusion like is 10 inch better or 8 ¼ inch better, the answer is 10 inch is most suitable for professionals for work sites which involves heavy wood work and 8 ¼ inch would be preferable by home owners and DIYer’s. Hope this would be of help for the consumers to decide which Dewalt model would be suitable for them based on blade size.
Thank you for reviewing these saws, one important thing all should do before making the purchase, after reading these reviews. Once you’ve selected a saw you like from this review, look at consumer reviews of the saw you’re leaning towards buying to see what experience people have had over time using the saw. To review a saw out of the box is fine for it’s features etc., how it performs over time is also very important. There is one other, service from the manufacturer. Is the manufacturer in the habit of making models obsolete, and therefore parts can no longer be available, such as the Ridgid saw I purchased. Food for thought.

DEWALT table saw holder, mobile / rolling (DWE74911)

If you’re working out of your garage, you may not have room for a full-size, standalone table saw. There are several tabletop models available that provide a smaller (and typically less expensive) alternative with the same wood-cutting capabilities. However, if you do have room for a full-size model, these are generally more versatile and powerful.
They are common, the lightest, and perhaps the cheapest. Portable table saw reviews show that these kinds of saws are the popular choice for homeowners looking to carry out simple tasks. The motors aren’t that powerful, some have tabletops that are retractable and can be moved from one place to another. They are inexpensive. The problem is that most have poorly built miter gauges and fences. 

10 inch DEWALT DW745R Table Saw

Balancing heavy-duty durability and lightweight design, this machine proves that good things can come in small packages. While buyers are overall happy with their purchases, they do seem to all agree on one thing: the DEWALT DWE7480 may be an overall investment, but it could seriously do with a miter gauge replacement. Buyers report replacing its inaccurate, plastic gauge for a solid, more detailed one.

The first step always has to be to make sure that you match a saw with your actual needs. It’s a pretty simple thing to go out and buy the biggest, angriest saw available and call it good. But your genuine needs might be modest enough that the biggest, angriest saw is also too much saw, which means that you’re just throwing away a bunch of money. The same goes for weight. If you’re a small-framed person who has difficulty lugging around heavy, bulky objects, you’ll want to tailor your saw to your frame. If you can’t use it, it’s the same thing as not owning it.
