HOPRIO angle grinder uses brushless motors. Compared with traditional tools, there is no problem of frequent replacement of carbon brushes and rotors. With the same power, hoprio brushless angle grinder can be smaller and easier to operate，The tool can realize constant speed function at any set speed and achieve low speed and high power output.The motor can achieve a wide range of speed regulation from 3000-30000rpm. Brushless tools can significantly reduce labor costs, consumable losses, maintenance costs, etc.
