Buyers should pay attention to the fact that during installation, the rod of the saw blade should be plugged all the way. In the case of high speed, the inertia will cause it to change the bearing track, and the rod of the saw blade can be bent, causing unnecessary loss and damage 2. The speed of the machine using the saw blade should not exceed 20,000 rpm. It is recommended to use a speed controlled machine. Normal speed is 0 to 20,000 rpm. For small electric grinders, try to use a saw blade with a small outer diameter, because the electric grinder is small and light. The front half of the machine is heavy, which will cause the machine to vibrate at high speeds, thus affecting the cutting precision. 3. When using the saw blade, be sure to use it safely and wear all kinds of safety protective equipment.
