Understanding Your DeWalt 745 Table Saw
The DeWalt 745 table saw is known for its compact design and exceptional portability, making it a go-to choice for contractors and DIY enthusiasts alike. Before we dive into the specifics of changing the saw blade, it’s important to understand the components of your saw.
Key Components of the DeWalt 745
- Blade Guard: A protective covering that keeps your hands safe while cutting.

Why Change the Saw Blade?
Changing the saw blade regularly is vital for various reasons:
1. Performance
A sharp blade makes cleaner, smoother cuts, improving the overall finish of your work.
2. Safety
A dull blade requires more force to cut, increasing the risk of kickback or losing control of the saw.
3. Versatility
Switching out blades enables you to work with different materials, whether it be wood, metal, or plastic.
Essential Tools and Safety Gear
Before getting started, it’s crucial to gather the necessary tools and wear appropriate safety gear.
Tools Needed
- Replacement saw blade (ensure it’s compatible with DeWalt 745)
- Wrench (often included with your saw)
- Screwdriver
- Sharpie (for marking any adjustments)
Safety Gear
Don’t overlook the importance of personal safety. Always wear safety goggles to protect your eyes from flying debris, and consider wearing ear protection to guard against noise. Gloves are optional, depending on your comfort level, but ensure they are tight-fitting to avoid snagging.
Step-by-Step Guide to Changing the Saw Blade on the DeWalt 745
Now that you’re aware of the tools and safety measures, let’s move on to the crucial steps for changing the saw blade.
Step 1: Unplug the Saw
Your safety is paramount. Start by unplugging the DeWalt 745 from its power source. This eliminates any chance of accidental activation while you’re working on it.
Step 2: Remove the Blade Guard
Locate the blade guard and carefully detach it. Most guards have a quick-release mechanism that allows you to remove them easily. If necessary, use a screwdriver to loosen the screws holding the guard in place.
Step 3: Adjust the Blade Height
Use the height adjustment mechanism to lower the saw blade. Lowering the blade makes it easier to access the arbor nut and prevents any accidental cuts while working on the saw.
Step 4: Loosen the Arbor Nut
With the wrench provided with your saw, turn the arbor nut counterclockwise to loosen it. This can sometimes require a bit of force, so be prepared. A locking mechanism makes it easier, as it often holds the motor in place while you work on the blade.
Step 5: Remove the Old Blade
Once the arbor nut is loosened completely, carefully remove the old saw blade from the arbor. Take note of how the blade is oriented, as you will want to replicate this placement when installing the new blade. The teeth of the blade should always face towards you when it’s mounted.
Step 6: Install the New Blade
Place the new blade onto the arbor, ensuring it goes on in the same orientation as the old one. Remember, teeth pointing down and towards you. Replace the arbor nut and tighten it securely, turning it clockwise. If your saw has a blade washer, make sure it’s seated correctly beneath the blade.
Step 7: Reattach the Blade Guard
Once the new blade is securely in place, reattach the blade guard. This is an essential safety feature that must be properly fitted before you use the saw.
Step 8: Test the Setup
Before you begin cutting, it’s wise to perform a quick test. Plug the saw back in and turn it on briefly to ensure everything is working correctly. Watch for any unusual noises that may indicate a problem with the blade installation.
Tips for Maintaining Your DeWalt 745 Table Saw
Keeping your DeWalt 745 in top condition requires more than just changing the blade. Here are some maintenance tips to extend the life of your saw:
1. Regular Cleaning
Dust and debris can accumulate quickly. Clean your saw’s surface, as well as the blade, after every use to keep it working efficiently.
2. Check Blade Alignment
Periodically check the alignment of the blade with the miter gauge and rip fence to ensure accuracy in your cuts.
3. Store Properly
When not in use, store your saw in a dry environment to prevent rust and corrosion. Consider using a protective cover for extra safeguarding.
4. Inspect the Power Cord
Regularly inspect the power cord for any signs of wear or damage. A faulty cord can lead to electrical hazards.

The DeWalt 745 is versatile and compatible with a variety of saw blades. For general woodworking, a combination blade with 40 to 60 teeth is typically recommended for a balance of fast cutting and smooth finishes. If you plan to cut specific materials like plywood or laminate, a blade designed explicitly for that material will yield better results by minimizing splintering.
It’s also essential to choose the right diameter for your blade, which is 10 inches for the DeWalt 745. Always ensure that the blade is rated for the specific settings and features of your saw to maintain safety and efficiency during operation.
Do I need any special tools to change the blade on the DeWalt 745?
To change the blade on your DeWalt 745, you will typically require a wrench to loosen the arbor nut. Most DeWalt saws come with a blade wrench included. Make sure you have this tool ready before starting the blade replacement process. Additionally, having a wooden block handy can help secure the blade when loosening or tightening the arbor nut, preventing it from rotating.
It’s also essential to have a clean workspace and safety gloves when handling the blade, as it can be sharp and dangerous. Before proceeding, ensure the saw is unplugged to avoid any accidents while you work on the blade change.
Can I use a different brand of blade on my DeWalt 745?
Yes, you can use blades from different brands on your DeWalt 745 as long as they match the required specifications of the saw, including size and arbor size. Many high-quality aftermarket blades are available that can provide better performance or specialized cutting abilities for specific materials. When choosing a blade, look for one that is compatible with a 10-inch diameter and has a 5/8-inch arbor.
However, while you can use different brands, ensure that the quality of the blade meets your needs. Researching user reviews and recommendations can help you select an aftermarket blade that is durable and performs well with your DeWalt 745.
Is it safe to change the saw blade myself?
Changing the saw blade on your DeWalt 745 can be done safely if you follow the proper procedures and take necessary precautions.
