Diablo Demo Demon Vs Milwaukee Ax Carbide: Who’s Faster?

Diablo Demo Demon Carbide-Tipped Recip Blades

As carbide makes its way onto more saw blades, two companies are emerging as the leaders in wood cutting reciprocating saw blades: Diablo and Milwaukee. The advantage of carbide isn’t pure speed. In fact, many bi-metal blades with a more aggressive tooth count and geometry will cut faster than either of these two blades. The advantage lies in longevity. Carbide lasts much longer – 50 to 75 times longer in some cases – than bi-metal, easily paying for itself many times over. But the question remains in the Diablo Demo Demon Vs Milwaukee Ax Carbide debate – who’s faster?

Diablo Demo Demon Vs Milwaukee Ax Carbide

We set up some tests from real world to scientific to see which blade will cut faster through 2 x 12 PT pine embedded with five 16D nails. For the first test, it was straight up Clint (Diablo) Vs Kenny (Milwaukee) and whatever technique we wanted to use to get the fastest cut.

Freehand Results

  • Diablo: 25.95 seconds
  • Milwaukee: 27.06 seconds


If you watch the video, you’ll see there’s some pretty clear variance in our techniques, so we can hardly call this definitive. But yes, Clint does get to put another notch in the win column.

From a controlled setting, we put 10 pounds of weight on our Milwaukee M18 Fuel Sawzall with One-Key and let the blade and motor do the work just like we did in our cordless reciprocating saw shootout.

Weighted Results

  • Diablo: 38.6 seconds
  • Milwaukee: 26.9 seconds


With no rocking the saw and equal downforce, Milwaukee comes out as the clear winner in speed.


Milwaukee’s advantage in the controlled test comes down to blade design. Milwaukee’s teeth are the same over the length of the entire blade while Diablo employs a variable tooth design that changes over the length. As you adjust the shoe or use a different length of blade, you’re going to get some varying results. We can make the argument that the shorter length would have been a better bet for this test – but in keeping things apples to apples, we had 9-inch lengths for both and it’s the length you’re most likely to find on site.

Diablo Demo Demon Vs Milwaukee Ax Carbide: Who's Faster?

Keep in mind that this is just one test for Diablo Demo Demon Vs Milwaukee Ax Carbide. It doesn’t take into consideration blade life or materials you’ll run into other than PT and standard galvanized nails.

The real difference is cost. I love the ax. But they are $11-15 each. The Diablos are 3 for $26….. That’s a win. But. The Diablo is a much thinner blade. The ax is thicker/stronger and don’t flex as much in real demo situations. That’s a win. Both blades are very good
It all comes down to individual uses

The Diablo carbide won me over last year after I used a blade till it melted out of the sawzall. Cut up ALL the ply from the roof of a house, gutted a building, then cut up a bathroom floor that was 2 layers of 3/4 ply riddled with screws and tile. Right as I finish cutting up the floor the blade melted off the saw. Incredible compared to standard blades.
