how to change a blade on a dewalt reciprocating saw

If you’re like me, you have a lot of tools. And if you’re like me, you probably use your Dewalt reciprocating saw a lot. Well, I have some news for you: the blades on those things suck. They go dull fast and are a pain to change. In this post, I’m going to show you how to quickly and easily change the blade on your reciprocating saw. Let’s get to it!

Some Important Steps

1. Find a replacement blade and remove it from the packaging

2. Take the locking pliers and clamp them onto one of the teeth 

3. While holding down that tooth, use your other hand to rotate the blade counter clockwise until the old blade comes loose (it may take a few seconds)

4. Repeat steps 2 and 3 for however many teeth your blade had

5. Place the new blade into the housing and rotate it clockwise to move all of the teeth into place (you may need to use a little more force than you did in step 5)

6. Use the locking pliers to tighten up each tooth one by one until they are firm

What type of blade do you need for the project you’re working on? 

We’ve got you covered! We have a wide range of blades that are of better quality and will increase your productivity. 

Do these blades come in different sizes? 

Yes! Our Dewalt Sawzall blades come in 5 different sizes, ranging from 2 to 12 inches long. We also carry the corresponding arbors for each size so you can quickly change them out on your reciprocating saw.

Why buy replacement Jigsaw Blades when could easily make one yourself with a piece of sandpaper?

In most cases, you need a new blade when the old one is either bent or has been worn down to a point where it does not work very well anymore. In fact, making your own replacement blades from sandpaper is probably more time-consuming than going out and buying a new one. Also, if you have had a lot of experience working with sandpaper on wood projects, then this might be a good option for you! If you’ve never used sandpaper before or don’t remember how then this isn’t the project for you!

What grit size should I use on my Dewalt Sawzall blades?

For starters, it’s important that you know that there are different levels of roughness in sandpaper. Coarser papers have bigger gaps in between each grain, so they are rougher and take off more material with every pass. Finer papers have tighter grains, so they are smoother and will not take off as much material when you make a cut. For these Dewalt Sawzall blades we recommend getting the finest (lowest number) grit possible that will still do the job!

How to remove the old blade?

Typically, you can remove the old blade by simply pushing down on one of the teeth with a pair of locking pliers and turning the Sawzall blade counter-clockwise. If you don’t have locking pliers or something similar at your disposal, it may be necessary for you to use some sort of tool (a flat head screwdriver is usually sufficient) to pop each tooth out while you turn the blade. This is obviously much more difficult than just using locking pliers since it requires more individual actions.

What are Sawzalls?

A reciprocating saw, also known as a Sawzall, is defined as an adjustable-length power tool consisting of either an electric motor or gasoline engine a double-ended hacksaw blade that can be reciprocated rapidly back and forth, allowing the saw to cut through material such as wood or metal.

How to insert the new blade?

To put the new blade on your Dewalt reciprocating saw, you will first want to make sure that the teeth of the blade are pointing inwards. After this is done, all you need to do is insert it into the housing and turn it clockwise until the new blade is locked into place! This may take a little bit of turning and pushing depending on how well your old blade’s teeth were seated. Once the blade is seated, you simply tighten it up with the locking pliers.

How to take off a Dewalt Sawzall blade?

To remove the old blade from your Dewalt reciprocating saw, turn the blade counter clockwise until it pops out of its housing. If this doesn’t work, try inserting a flat head screwdriver into the blade and using it as a lever to pop up each individual tooth.

What tools do I need?

In order to work on your Dewalt reciprocating saw, you will need either locking pliers or some sort of tool (such as a flat-head screwdriver) that can help you push down the saw blade’s teeth while you turn the saw.

While our Dewalt reciprocating blades are not as cheap as others on the market, they were designed to fit the Dewalt Sawzall. If you want quality that lasts then this is your best bet! Do yourself a favor and save yourself some hassle by buying these high-quality replacement blades before you get a chance to damage your new blade.

Tips for keeping your saw running well?

First, make sure that you clean your saw after each use. Lubricating it every once in a while, with oil or WD-40 will ensure that it doesn’t lock upon you! After cleaning the blades and activating the high tooth count blade, you should also check for any chips in the teeth of your knife. If there are any, use a metal file to remove them before they get in the way of your project.


So, there you have it. Changing the blade on a Dewalt reciprocating saw is not as hard as it may seem. Just make sure that you have all of the necessary tools and follow these simple steps, and you should be able to do it in no time at all!
