Why not hammer drill iron
The characteristics of the electric hammer drill:1, a good shock absorber system: allows the operator to hold comfort, relieve fatigue.The way to realize is realized by vibration control system;Through the soft handle increased comfort grip;2 、 accurate speed control switch: when the touch switch is lower, it can help the machine to drill smoothly (for example, drilling on the smooth surface of tile, not only prevents the drill from slipping, but also prevents the hole from breaking. High speed can be used during normal work to ensure efficiency.3, stable and reliable safety clutch: also known as the torque limiting clutch, avoid large torque during use due to seizure caused by the reaction of bit transfer to the user, this is a kind of safety protection of users. This feature also prevents the gears and motors from stopping rotating.

Is the drill fast to feed, easy to break, or slow to feed, easy to break?
The feed is fast, the drill bit is still constant, the feed is fast, the amount of cutting per tooth is large, the cutting force is large, and when it exceeds the strength limit of the drill, the drill will break. Feed too slowly is easy to wear drill bit, because the feed is too slow, cutting edge cutting more times, so easy to wear.
8mm iron expansion bolts with few drilling drill mm?
