Shopping tips:
1, be sure to choose an electric hammer with a speed regulating switch. The touch switch has a low rotating speed, which can help the machine to trip out smoothly (for example, tripping out on smooth surfaces such as ceramic tiles can prevent the drill bit from slipping and the drilling hole from breaking), and it can use high speed during normal operation to ensure work efficiency.
2. Both positive and negative functions are indispensable. When drilling a hole in the wall with an electric hammer, it is inevitable that the drill bit will get stuck. At this time, just turn it in the opposite direction and gently pull it out, and the drill bit will come out. If there is no reversing function, it will be very laborious and easy to get hurt.
