This blade (7-1/4 Construction) is 1.8mm thick. Many other blades advertise "thin kerf" or "thin cut" that are like 0.8 mm. While thin kerf saves a tiny bit of material, thin blades are prone to flexing sending your cut-line off course. This can result in a poor quality cut or even scrapping your piece. I use a corded electric circular saw. Great combination.
