Hammer choose what precautions
Tungsten carbide cross drill, mainly used for all kinds of brick and slightly lower grade concrete drilling, its processing caliber is big, so the power of equipment is also big, usually specifications for the diameter of 30 ~ 80mm.
According to the size of the workload and their own economic ability and selection of hammer. Imported equipment has better performance and higher price. In recent years, domestic electric performance has been greatly improved, the price is relatively cheap, if used properly, will not affect the construction quality. Hammer of the specification is based on the input power division, power drill ability, break through the capacity is strong, but also a corresponding increase in weight. Secondly, it is better to make equipment processing ability than work requirements slightly larger, generally should work requirements than large 10%, 20%, so as not to damage the machine.
There are usually ordinary electric hammer hammer and gas hammer. Electric gas hammer with high pressure air driven hammer drill, due to the compressibility of the air itself is strong, it can avoid the other hammer rigid collision generated by mechanical transmission, so that the vibration is reduced, without pressure operation, time saving, hold steady, flexible operation.
The choice of bits depends on the nature of the work. Often used are: tungsten carbide cement bit, tungsten carbide cross drill, pointed chisel, flat chisel, ditch chisel. Tungsten carbide cement bit is mainly used for drilling various strength grades of concrete, and the most commonly used specifications are diameter 5 ~ 38mm.
