The DEWALT DW3984 bi-metal portable band saw blade is built for tough metal cutting jobs. Each blade features a Matrix II high-speed steel edge with 8% cobalt content and an Rc 65-67 tooth hardness, providing outstanding heat and wear resistance. The alloy steel backer resists fatigue and breaking, making these blades a reliable choice for professional and DIY use. This 3-pack gives you long-lasting replacements for your portable band saw.
The combination of high-speed steel and cobalt increases durability, so the blade stays sharp longer and handles the stress of cutting steel, stainless steel, and other metals. With 24 teeth per inch (TPI), you get smoother cuts in thin materials and tubing.
Designed to fit DEWALT portable band saws and many other brands using a 44-7/8" length blade. Check your saw's blade specifications to confirm compatibility.

24 TPI delivers smooth, fast cuts in thin metal and pipe. For heavier materials or thicker stock, consider a blade with fewer TPI (e.g., 18 or 14). The DW3984 is optimized for general metal cutting on portable band saws.
Matrix II high-speed steel is a premium formula that retains hardness at high temperatures. The 8% cobalt content boosts wear resistance, while the alloy steel backer absorbs shock and resists breaking. This combination gives you longer blade life than standard carbon steel blades.
Use cutting fluid or lubricant when sawing steel to reduce heat and extend blade life. Apply steady, even pressure and let the blade do the work. Avoid twisting the blade in the cut, as this can cause premature breakage.
It is designed for DEWALT portable band saws that use 44-7/8" blades, such as the DW0820, DCS372, DCS378, and similar models. Always check your saw's blade length requirement.
The bi-metal construction with 8% cobalt makes it ideal for cutting steel, stainless steel, aluminum, and other metals. The 24 TPI is suited for tubing, pipe, and thin materials.
Loosen the tension on your band saw, slide the blade on, and ensure the teeth are pointing in the direction of rotation. Tighten the tension and track the blade before operation.
Yes, the DW3984 includes three individual blades.
Sharp and strong.
These blades last longer than the original. They cut metal cleanly.
I use a portable band saw on job sites. These blades are durable. They stay sharp even when cutting steel. The 24 TPI gives a smooth cut. The price for a 3-pack is good. I've bought them twice now.
Good quality blades. They fit my saw perfectly.
Work great.
