now I will introduct about how to drill safety. Firstly, to drill safety you have to drill a pilot hole before and then drill by the larger bit, to prevent the drill from slipping and other damage. Also you have to hold the drill steady during drilling into the material. Then you should adjust the torque by the collar with a series of number. You know the bit can be overheat, so you should start with low speed and then speed up if the drill isn’t move smothly. One attention that is don’t force or run the drill when the drill get stuck in the material. You must unplung and separate the bit and the chuck and then remove the bit
