A drill and electric hammer selection problem
Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill.Drilling machine using electric power as power. Is the power tools in the conventional products, but also the largest demand for power tools products. 35% of China's power tools are produced and sold each year. The main specifications of electric drills are 4, 6, 8, 13, 16, 19, 23, 32, 38, 49mm, etc. the figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm2 ().
The ordinary electric hammer line hanging head diameter 12 hammer hanging home with enough Diangao you don't foam 1 wall so you directly on the OK screw Ning are popular nowAnd when you hit the tiles, don't hold it loosely. It's not broken... Hammer East into just don't need to buy STANLEY Electric is Dr. xilide tick worse
It seems that you are love yourself, what principle out of order are nonsense, if the home, buy a hand drill dual-purpose impact drill, don't feel bad money, cheap goods is not good, I chose the BOSCH power tools, a household is more than 200, enough, not like a hammer on my home. Almost what tools are above is another problem you have wise remark of an experienced person, tile, now need the family decoration as beautiful, with percussion drill tile will make sure to buy a dozen flower tiles, tile special drill, still recommend BOSCH, the first electric drill pattern with the tiles penetrated brick tiles (there is absolutely no then, for defects) impact drill with impact mode continue to play, as in the end what effect depends on your level. Electric tools choose BOSCH or MAKITA, not to mention what I worship, when they can catch up with their Chinese level I definitely choose domestic products. In fact, really not expensive.
