Pros and Cons
There are benefits and disadvantages to anything and also to the 10- inch and 12-inch table saws. Let’s look at some of them.

Accessories or Lack Thereof
In some sense, you could call the 12-inch blade the poor cousin of the two as it comes without all the accessories available for the 10-inch blades, like Tenon jigs. Twelve-inch blades are also harder to find.
The availability of accessories for 10-inch blades is much better. You can find an almost exhaustive range of saw blades for 10-inch saws at just about hardware store or lumberyard.
One major downside to owning a 12-inch table saw is finding good quality blades. The local hardware outlet usually only stock thin-kerf blades geared toward miter saws.

The advantage of the bigger size blade diminishes with poor quality and as mentioned before, you have to search to find good quality 12-inch blades.

To start with, have your blade as high as it will go. Carefully push the wood at a slow and steady pace through the saw. The wood won’t be cut through completely.
