[high torque]: the cordless screwdriver is equipped with a brushless motor and has a maximum torque of 230nm and a maximum impact rating of 3300 ipm. that's why this cordless screwdriver can easily meet different requirements when screwing into different materials such as wood, plastic, metal or other materials. [3 speed control]: the cordless screwdriver can be set to 3 different speeds. the low speed (0-800 rpm) provides high torque and is suitable for screwing in hard materials. medium (0-2000rpm) and high speed (0-3000rpm) speeds offer lower torque but faster speed, making them ideal for screwing into soft materials or other jobs. you can choose different speeds according to your needs or activate the smart mode to adjust automatically.
