Hammer open hole in the wall or flat impact drill
Impact drill work in a drill chuck adjustment knob, adjustable drills and impact drills in two ways. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It can also drill steel and concrete, but the results are poor.Hammer (hammer) is not the same, it is to use the bottom two sets of motor driven gear structure, a realization of it drill, and another one is to drive the piston, a hydraulic engine stroke, resulting in a strong impact force, along with the drilling results. Power can crack stone and metal
I'm not good at it, but I know a little about that, because I've been punching holes in my walls recently, and one of them needs to be noticed:If your walls are ordinary concrete / cement wall, you on the side of good side impact drill, no problem. What if you have a wall tile things easily broken, do not use impact, otherwise it will put the surrounding tiles broken, can only use flat drill to drill the surface slowly, etc. drill through a kind of ceramic tile, and vibration, but also very careful.
Open the hole in the wall or the impact hammer drill according to specific flat wall material to the decision:1, if the wall belongs to the concrete structure or brick structure, electric shock function Zhong recommended.2, if the wall belongs to the civil structure, recommend the use of electric bell flat drill function.
