Dewalt, a leading brand in construction tools, offers a range of high-quality reciprocating saws designed for durability and performance.
Types of Dewalt Reciprocating Saws
Dewalt offers several models of reciprocating saws, including:
- Corded Reciprocating Saws: Ideal for heavy-duty tasks where consistent power is required.
- Cordless Reciprocating Saws: These are portable and convenient for jobs where power outlets are not available.
Understanding which type you have can influence how you change the blade, but the principles remain largely the same across models.
Selecting the Right Blade
Choosing the correct blade for your project is crucial for efficiency and the quality of the cut. Dewalt offers a variety of blades for different applications.
Types of Reciprocating Saw Blades
There are primarily three types of blades you might consider:
- Wood Cutting Blades: Typically featuring fewer teeth per inch (TPI), these blades are designed for faster cuts in wood.
- Metal Cutting Blades: These have more TPI and are designed to make clean cuts in metal, ranging from thin sheet metal to pipes.
- Multi-Purpose Blades: These blades combine features for cutting wood and some metals but are often less efficient than specialized blades.
Choosing the right blade not only simplifies your cutting project but also ensures that your saw operates optimally.
Gathering Your Tools
Before you begin the blade change process, gather the necessary tools:

Having everything at hand will make the process smoother and more efficient.
Steps to Change Dewalt Reciprocating Saw Blades
Now that you have your tools and understand the types of blades, let’s dive into the steps for changing the blade on your Dewalt reciprocating saw.
Step 1: Disconnect the Power Source
Safety is paramount when working with power tools. Whether you have a corded or cordless model, ensure that the tool is completely powered down. For corded models, unplug the saw. If you have a cordless model, remove the battery.
Step 2: Locate the Blade Release Mechanism
Different models may have different blade release mechanisms. Dewalt saws typically feature either a tool-less blade change system or a screw-based system.
Tool-Less Blade Change
For many modern Dewalt reciprocating saws, you can simply pull the lever or slide the clamp to release the blade.
Screw-Based System
If your model uses screws, you will need to use a screwdriver to loosen the screws holding the blade in place.
Step 3: Remove the Old Blade
With the blade release mechanism engaged, carefully pull the old blade out of the chuck. If it’s stuck, wiggle it gently back and forth until it comes loose.
Step 4: Insert the New Blade
Take your new, appropriate blade and slide it firmly into the chuck of the saw. Ensure that it fits snugly and is properly aligned.
Locking the Blade
For tool-less systems, close the release lever until it clicks. In screw-based systems, tighten the screws securely to hold the blade in place.
Step 5: Verify Blade Installation
Before moving on, it’s wise to double-check that the blade is installed correctly. Give it a gentle wiggle; it should not move or come loose.
