One issue is the arbor length, which will not provide enough space for a dado stack as well as the tightening nut to thread completely onto the arbor. As you can see on DeWALT’s FAQ section for the model itself, they state that “No similar to our other compact table saws (DWE7485 and DW745) the unit does not accept DADO stacks.” This is also addressed in the Instruction Manual supplied with the table saw, on page 15 under “Saw Blades,” adding that personal injury may occur if a dado blade is used.
Unfortunately, the DeWALT DW745 is not compatible with a stacking dado blade set or with a wobbling dado blade. Check Today's Price The DeWalt DW745 Dado Blade Dilemma
