What is a percussion drill

Impact drill, also known as impact drill, is a kind of power tool used for drilling bricks, blocks and light walls and other materials, mainly rotary cutting, both rely on the operator thrust to produce impact force impact mechanism, with vertical reciprocating movement to rely on impact force for drilling, its working principle is similar to the hammer drilling.

The structure of a hammer drill consists of a power switch, a reversing limit switch, a drill chuck, a power supply voltage regulator and a clutch control twist, a two-stage speed change mechanism for changing voltage, an auxiliary handle, a positioning ring, a shell setting screw, a forward and reverse steering control mechanism, a gear set in the machine, and an insulating handle for the housing.

Second, what is the hammer drill used for

Hammer drill is more commonly used in construction projects, and its uses mainly have two points:

1. Drilling

Push the drill bit part of the hammer drill back, put it into a suitable drill bit, align it with the place to be drilled, hold it tight, press the switch, and then rotate the drill bit to create a hole in the brick or wall.

2. Chisel the wall

In addition to rotary drilling, the impact drill also has the effect of forward impact drilling. As long as the drill bit is replaced with a flat chisel or a pointed chisel bit, adjust to the impact gear of the impact drill, and then use normally, you can drill the wall.

Third, the advantages and disadvantages of percussion drill

Percussion drilling relies on impact force for drilling operations, and its advantages and disadvantages are more prominent:

1, the advantages of percussion drill

Hammer drill has good drilling performance, can effectively drill hard strata, and relatively high efficiency, especially suitable for high hardness rock, weathered rock and a variety of hard and brittle geological environment.

2, the shortcomings of percussion drill

The main reason is that it is more difficult to remove debris, and it is very difficult to drill geological holes in soft geology and high viscosity soil layers. In addition, the use of percussion drill has certain limitations.

4. Range of use of percussion drill

The percussion drill is mainly used to punch holes on concrete floors, walls, bricks, stone, wood and multi-layer materials. Drilling and tapping can also be done on wood, metal, ceramic and plastic.
