Review on 🔧 7.25 X 70 Ferrous Ultrafine by Robert Dabney

Used this blade on my saw table for its very fine kerf. I reduced the blade rotation speed to 1800 rpm by putting a smaller diameter pulley on the motor shaft. Half the speed and twice the torque. Make dozens of bevel cuts on square metal tubing. Feed slowly to avoid sparking and prolong blade life. Sparking means that the metal being cut is heated and solidified by this heat. Once the path you're cutting gets hard, it will begin to blunt the tips of the carbide blades, creating even more heat. The only problem I have is that the red paint is so slippery that the saw arbor spins faster than the blade. I had to sand the middle part to remove the red slippery paint.
