Among the various attachments you can use with your table saw, the dado blade stands out for its ability to create precise grooves and intricate joinery. However, if you’re a proud owner of the DeWalt DW745, you may have found yourself wondering, “Can I use a dado blade on my DeWalt DW745?” In this article, we will dive deep into the usability of dado blades on the DW745, discuss alternatives, clarify safety considerations, and explore how to make the most of your tool without compromising quality or safety.
Understanding the DeWalt DW745 Table Saw
Before we tackle the question of dado blades, let’s first familiarize ourselves with the DeWalt DW745 table saw.
Key Features of the DeWalt DW745
The DW745 is a compact and portable table saw designed for both professionals and hobbyists. Some of its key features include:
- Powerful Motor: The DW745 comes equipped with a 15-amp motor capable of delivering a no-load speed of 3,850 RPM. This provides adequate power for cutting through various materials.

What is a Dado Blade?
A dado blade set is a specialized type of circular saw blade that allows you to make wider grooves or trenches in your woodwork. Unlike standard blades, which can only cut along the diameter, a dado blade can cut across its width, making it ideal for joints and shelving.
Types of Dado Blades
There are generally two types of dado blades available in the market:
- Stacked Dado Blades: This type includes two outer blades and several chippers. The chippers are added to increase the width of the cut.
- Wobble Dado Blades: These blades feature a single blade with an adjustable angle, which allows for varying widths of cuts. However, they are less common due to the less clean cut compared to stacked blades.
Compatibility of Dado Blades with DeWalt DW745
Given its specifications and design features, the crucial question arises: Can the DeWalt DW745 accept dado blades?
Manufacturer’s Recommendations
According to the manufacturer’s guidelines for the DeWalt DW745, using dado blades is not recommended. One of the main reasons stems from the design of the saw, specifically its arbor size and clearance. The DW745 has a 5/8-inch arbor, which is compatible with standard blades, but dado blades generally require greater clearance to function safely and effectively.
Potential Risks of Installing a Dado Blade
While it might be tempting to use a dado blade on the DW745, several risks come with this decision:
- Saw Performance: The DW745 is not designed to handle the additional torque and stress exerted by dado blades, potentially leading to motor burnout or other mechanical failures.
- Safety Hazards: Attempting to use a dado blade can result in kickback, improper cuts, or even serious injuries. The sliding action and the added weight of a stacked dado set require specific adjustments and powerful machinery to maintain control.
Alternatives to Dado Blades on the DW745
Fortunately, while you may not be able to use a dado blade on the DW745, there are several alternatives for creating grooves and joinery:
1. Router and Dado Router Bits
Using a router fitted with a dado bit can successfully create similar grooves. A router allows for more control over the depth and width of the grooves, ensuring accuracy.
2. Circular Saw and Straight Edge
If you’re looking for an efficient way to cut wide grooves, you can also use a circular saw alongside a straight edge as a guide. This technique works best for longer cuts and can be quite effective when making grooves for shelving or joinery.
3. Hand Tools
Sometimes, the old-fashioned way is the best solution. With hand chisels and a marking gauge, you can carefully carve out dados with precision. While it may require more time, it also focuses on craftsmanship and attention to detail.
4. Investing in a Dado-Compatible Table Saw
If dado cuts are essential to your woodworking projects, you might consider investing in a table saw that explicitly supports dado blades. Many models designed for professional woodworking offer integrated safety features and designs that accommodate dado sets more effectively.
Safety Best Practices When Using Table Saws
Regardless of the type of blade you use with your table saw, safety should always be your top priority. Here are some practices to ensure safe operation:
Proper Tool Operation
- Read the Manual: Always refer to the manufacturer’s manual for specifications, recommendations, and safety precautions.
- Use Personal Protective Equipment (PPE): Always wear eye protection, hearing protection, and avoid loose clothing that can get caught in moving parts.
Setup and Environment
- Stable Work Surface: Ensure your workspace is clear and stable, reducing the risk of material movement during cutting.
- Check Blade Condition: Always inspect your blades for any damage before each use. A dull or damaged blade can pose significant safety hazards.

Can I use a dado blade on my DeWalt DW745 table saw?
Yes, you can use a dado blade on your DeWalt DW745, but with some important considerations. The DW745 is not designed for dado blades out of the box, as it typically comes with a standard carbide-tipped blade. However, if you seek to use a dado blade, you may need to upgrade certain components, like the throat plate and arbor length, to accommodate the dado stack.
Before you proceed, be sure to consult your owner’s manual to confirm the compatibility and restrictions related to the use of dado blades. It’s essential to ensure that all safety protocols are followed to avoid accidents and damage to your saw. When set up correctly, your DW745 can handle dado cuts efficiently, but always remember to exercise caution.
What modifications do I need to make for using a dado blade?
To use a dado blade on the DeWalt DW745, you will first need an appropriate dado throat plate that can accommodate the width of the dado stack. The stock throat plate may not support the wider blade configuration. You may have to purchase an aftermarket or custom-made throat plate to ensure a snug fit and to avoid kickback during operation.
In addition to the throat plate, check the arbor length. A standard dado stack often requires a longer arbor than what is provided with the DW745. If it does not have enough length, you may need to look for an adapter or an alternative saw model with a longer arbor specifically designed for dado blades.
Are there specific dado blade sizes recommended for the DW745?
While the DeWalt DW745 can theoretically accommodate dado blades, it’s advisable to use smaller stacks that do not exceed 6-8 inches in diameter. Larger dado blades might not fit or function properly due to the restrictions in the table saw’s design. Using a smaller dado blade stack also minimizes the risk of overloading your saw.
Additionally, the depth of the cut should be monitored, as the motor’s capacity is a consideration. Dado blades typically operate well with a maximum width of 13/16 inch. Be sure to verify the blade specifications and ensure that your setup allows for safe operation, as maintaining precision is crucial for effective dado cuts.
Will using a dado blade affect my warranty on the DW745?
Using a dado blade on your DeWalt DW745 may have implications for your warranty coverage. Most manufacturers, including DeWalt, specify that using accessories not approved for your specific model can void the warranty. If you modify the saw or utilize non-standard parts, it could lead to potential issues if you seek warranty service in the future.
Before you make any modifications or utilize a dado blade, it’s always a good practice to contact DeWalt customer service or consult the warranty information for your specific model. Understanding the limitations and guidelines can help you preserve the warranty while still exploring your cutting options.
What safety precautions should I take when using a dado blade?
When using a dado blade, safety should always be your top priority. Make sure to wear proper PPE (Personal Protective Equipment), including safety glasses and hearing protection, to safeguard yourself during operation. Always inspect your dado stack and saw for any potential issues, such as loose parts, before starting your cuts.
It’s also crucial to ensure your workpiece is secured firmly against the fence to prevent kickback. Avoid wearing loose clothing or jewelry that may get caught in the saw. Always follow the manufacturer’s guidelines regarding feeding speed and depth of cut, as well as any specific recommendations for using dado blades to enhance safety.
Can I use a different brand of dado blade on the DW745?
Yes, you can use different brands of dado blades on the DeWalt DW745 as long as they meet the specifications outlined for the saw. It’s important to check the dimensions, especially the arbor hole size and the maximum width of the dado stack, to ensure compatibility with your saw’s setup.
However, selecting a reputable brand known for quality can contribute to better performance and safety. Always read reviews and consider experiences of other users with the same machine to make the most informed decision regarding the dado blade that you choose.
