A device with a rotation number from 10 to 15 Nm is suitable for homework, and up to 130 Nm if you are a professional. Carefully read and remember that the torque means the internal force when the device is working.
Also pay attention to how many turns it makes in a second. From 400 to 500 turns will be suitable for homework, from 1200 to 1300 about / sec are considered as more professional. And the main indicator is power, the more it is on the device, the longer it will work. All batteries in the screwdriver must have a spare tire in the set in order for one to be in operation and the other to be on charge.
