One of the principal causes of table saw accidents is kickback. This process happens when a piece of wood is ejected at great speed in the direction of the user. Binding between the blade and fence, the wood then gets trapped in the teeth and spat out. A splitter is a vertical blade that holds the kerf open to minimize the chance of kickback. 2 pawls are attached for this purpose.
There’s a lot to like about this saw. The stand is easy to set up and very sturdy. We like the smooth-operating table extension and the blade guard’s hold-up feature and ease of installation. The only downside we found is that the motor mount is less rigid than those on the other saws we tested. We suspect that’s why the cut quality on our torture test was not as good with this saw.
Contractors who do a lot of finishing work and interior/exterior trim work know the value of a good portable table saw. DeWalt has built the DWE7490X from the ground up as a stable and safe job site cabinet saw that can be used to make those precision cuts quickly and easily without the need to pre-fabricate materials and then bring them to the job site for final fitting.
