Professional tool reviews for professionals

Due to its longer service life and the potential for fast and clean cutting, cemented carbide has entered almost all aspects of metal cutting. Diablo Steel Demon carbide thin metal reciprocating saw blades are now added to the product lineup, promising higher durability and cutting performance than bimetal saw blades.

When we cut thin metals (such as catheters), we often use bimetal blades in the 18 TPI range. However, Diablo's 12 TPI tooth count is more aggressive, but it works for them.

In the beginning, we noticed that these teeth bite into the metal, and we didn't jump around often when we started cutting.

As the cutting progresses, the 1-inch height of the blade helps to stabilize it, and its Perma-Shield coating makes it pass smoothly and reduces some of the jitter we usually encounter.

This coating can also persist well. Even when we repeatedly tested cutting and really heated up our EMT, we did not wipe it off as quickly as the other blades we tested.

All of these can achieve beautiful and fast cutting, but we don't want to ignore the cutting quality. For the 12 TPI design, Diablo left a surprisingly clean surface. In order to get the cleanest cut, we reduced the speed slightly. Of course, you also want to make sure that the orbital motion of the saw is turned off.

This is actually very obvious as we approach the useful life of the blade, because we will see rougher edges. When we started to see this, sure enough, we saw the first worn and broken tooth.

Let's talk about the price-because this type of cutting is where we see a lot of men and girls insist on using bimetal blades in the field. If you buy one 9-inch Diablo Steel Demon carbide thin metal reciprocating saw blade at a time, the price is $15.30.

The service life of Diablo's carbide teeth is 50 times longer than that of standard bimetal blades. The quality 18 TPI bimetal blades are priced at 3 to 4 US dollars each. Therefore, if you need to equip each Diablo blade with 50 blades, then you can buy blades worth 150 to 200 US dollars for every US$15 spent on thin metal steel demon.

Diablo's carbide thin metal reciprocating saw blades are an excellent choice for plumbers and electricians who need to cut thin metals on a regular basis. For MRO, modification and other aspects, they are part of a comprehensive series of carbide metal cutting inserts including medium and thick metals.

Try it yourself and see how the blade you get compares to your favorite bimetal blade. Be sure to come back and tell us what you think!
