- Wobble Dado Blades: A single blade that tilts to create a wider cut, but these tend to be less accurate and can leave a rougher edge compared to stacked blades.
Dado blades are perfect for creating joints, such as those found in cabinetry or furniture making, where precise wood-to-wood contact is necessary.
Benefits of Using Dado Blades
Using dado blades offers several advantages for woodworkers, such as:
- Precision: Dado blades allow for incredibly precise and clean cuts.
- Time-saving: With the ability to cut multiple grooves at once, users save time compared to traditional methods.
- Versatility: Dado blades can be used for various types of joints, including rabbet, dado, and half-lap joints.
Understanding these benefits further highlights the frustration many users feel when faced with the restrictions of the DeWalt DW745.

Why can’t I use a dado blade on my DeWalt DW745?
The DeWalt DW745 is designed primarily for cutting with standard saw blades, and its restrictions are mainly due to the design of the saw itself. The DW745 does not have the necessary modifications to accommodate a dado blade, which typically requires a wider arbor and sometimes a different configuration of the table and throat plate.
Using a dado blade can lead to safety concerns, as the saw is not equipped to handle the added stress and potential kickback that can occur with a dado cut. It’s crucial to use tools as they were designed to ensure both effectiveness and safety during operation.
What are the specifications of the DW745 that prevent dado use?
The specifications of the DeWalt DW745 indicate that it has a standard 10-inch blade capacity, but it isn’t built to handle the wider blades that are characteristic of dado sets. The saw’s motor and arbor size are also designed specifically for using conventional table saw blades, which limits the options available for different types of cutting.
Additionally, the throat plate on the DW745 is not adjustable to accommodate the varying widths of dado blades, which means even if you attempt to fit a dado set, the blade will not be properly secured or aligned. This misalignment can be dangerous when making cuts.
Can I modify my DW745 to accept a dado blade?
While some users may consider modifying their DeWalt DW745 to use a dado blade, this is not advisable. Such modifications can compromise the structural integrity of the saw and could lead to safety issues, including increased risk of injury from kickback or improper cuts.
