In this article, we are going to review the saw blade of Lenox company (LENOX LAZER CT CARBIDE), which is used for cutting thick metals. Before conducting a practical test with this saw blade, we will first discuss its features:
Number of teeth: With 8 teeth per inch, it is rougher than standard metal cutting blades. Of course, the Diablo razor has 8 teeth per inch and the Milwaukee razor has 7 teeth per inch.
Length: In terms of length, it is longer than both Milwaukee and Diablo razors. Of course, although the Lennox blade is longer, it is also more stable.
Thickness: It may seem reasonable to say that thick blades are needed to cut thick metals. The Lennox saw blade is thicker than the blades of the other two companies with an approximate thickness of 1.16 inches (1.3 mm). Of course, this advantage helps the stability of the Lennox blade when cutting.
Tip: You can feel the difference in the weight of this razor compared to the Milwaukee or Diablo product. The greater weight of the Lennox razor has made it cut more stably and of course less wobbly.

Saw blade performance test
In order to find out what performance and durability can be extracted from this Lennox carbide blade, 8.5 inch (16 mm diameter) rebar was used to perform a cutting test. At the beginning of the experiment, the cuts were done quickly, so that each rebar cut took an average of 7 seconds, and the fastest cut was done in 6.31 seconds.
Interestingly, while the cutting speed of the other 2 blades was decreasing, the Lennox blade maintained the cutting speed well. Until the 60th cut, the duration of each cut of this razor was less than 20 seconds. But Milwaukee and Diablo razors in the tenth cut, both had a record higher than 20 seconds.
Finally, when we decided to stop testing, the Lennox blade managed 69 rebar cuts, while the Milwaukee blade ended up with 42 cuts and the Diablo blade 24 cuts. This result shows the superiority of Lennox razor in terms of cutting speed and longevity.
What is the reason for all these differences?
When you are cutting thick and especially solid metals such as rebar, vibration and chatter take a toll not only on your hands, but also on the blade itself. Lateral movements cause the teeth not only to work along the cut itself, but to touch or cut the side walls of the cut. This hard and intense impact is the same vibration that you feel in your hand and sometimes you even see that the blade tries to jump back and forth.
The result is that the longer and thicker design that Lennox has provided for its razor has given it more stability. You, in turn, experience a faster, smoother cut along with longer blade life.
Now the price of this razor is 17 dollars, which is more expensive than Milwaukee with a price of 15 dollars or Diablo 13 dollars. Since this razor is top of the line, paying more is not unreasonable.

Other Features
The lifespan is more than 10 times compared to traditional razors that are made of two metals (Bimetal). High-quality carbides are welded to the body of the razor to increase durability and prevent the problem of tooth breakage.
Long blades enable direct cutting of objects with a large diameter, while the life of the blade increases.
Each tooth is engineered to make the blade work fast. Each wear tooth is precisely designed to cut hard metals quickly.

in the end:
Faster cutting and longer life, what more could you ask for in a horizontal saw blade that cuts through thick metals? This Lennox razor gives you both features, while competing with other razors, it is far ahead of the competition. So paying $2 or $3 more is worth the quality upgrade.
