The blades designed specifically for this saw ensure a perfect fit, which means smoother cuts and less wobbling. When I use the proper blade, I feel more confident because I know it’s engineered to handle the power and speed of the DCS391, reducing the risk of accidents.
Another reason I find these blades necessary is their durability and cutting precision. The Dewalt blades are made with high-quality materials that stay sharp longer, saving me time and effort because I don’t have to keep changing or sharpening them. Whether I’m working on hardwood, plywood, or framing lumber, these blades deliver clean, accurate cuts every time, which improves the quality of my projects and makes my work much easier.
Lastly, using the Dewalt DCS391 blades means I maintain the integrity of my saw. Generic or incompatible blades can cause unnecessary wear or even damage to the motor and components.

My Buying Guides on Dewalt Dcs391 Circular Saw Blades
When I first started looking for the perfect circular saw blades for my Dewalt DCS391, I quickly realized there are a lot of options out there. Choosing the right blade can make a huge difference in the quality of my cuts and the lifespan of my tool. Here’s what I learned through my experience and what I think is important to consider before making a purchase.
Compatibility with Dewalt DCS391
The very first thing I checked was whether the blade fits the Dewalt DCS391 circular saw. This model typically uses a 6-1/2 inch blade with a 5/8 inch arbor size. I made sure any blade I considered matched these specifications to avoid any fitting issues or safety hazards.
Blade Material and Durability
I found that the material of the blade impacts both its durability and cutting performance. Carbide-tipped blades are my go-to because they stay sharp longer and handle tough materials better than standard steel blades. Investing in a high-quality carbide blade means fewer replacements and better cuts over time.
Number of Teeth and Cut Type
Depending on what I was cutting, I picked blades with different tooth counts. For smooth, fine cuts in plywood or laminate, blades with more teeth (like 40 or more) worked best. For faster, rougher cuts in framing lumber, fewer teeth (around 24) made the job quicker and easier. I always considered the tooth design too—alternate top bevel (ATB) teeth gave me cleaner cuts on wood.
Blade Kerf and Thickness
The kerf—the width of the blade cut—is important because it affects how much material is removed and how hard the saw has to work. I preferred thin-kerf blades because they require less power and produce less waste, which is great for my battery-powered DCS391. Just make sure the blade is sturdy enough for the job despite the thinner kerf.
Specialty Blades for Different Materials
While most of my work involves wood, I’ve tried blades designed for cutting metal or plastic when needed. Dewalt offers multi-material blades that handle various materials without changing blades constantly. If you work with mixed materials, these can save time and effort.
Price vs. Performance
I balanced cost and quality by reading reviews and testing a few brands. Sometimes spending a little more upfront on a Dewalt-branded or high-quality aftermarket blade paid off because the blade lasted longer and cut better. Cheaper blades might save money initially but wear out faster and can damage your saw or workpiece.
Maintaining Your Blades
Lastly, I learned that taking care of my blades prolongs their life. Cleaning pitch and resin buildup regularly and sharpening the blades when needed keeps them performing at their best. Proper storage also prevents damage.
—
In summary, when buying Dewalt DCS391 circular saw blades, I focus on compatibility, tooth count, blade material, and intended use. These factors help me get precise cuts, extend blade life, and get the most out of my saw. Hopefully, my experience helps you make an informed choice for your next blade purchase!
