There are many varieties of power tools, and the world's power tools have developed to more than 500 varieties.

Three characteristics:

1. Lightweight structure, easy to carry and use.

2. Compared with manual tools, it can increase labor productivity several times to dozens of times;

3. Higher efficiency than pneumatic tools, lower cost, less vibration and easier to control.

Nine application areas:

1) In the machinery industry: drilling, tapping, sawing, rust removal, polishing, polishing, tube expansion and fastening of screws, bolts and nuts, etc.

2) Farmland reconstruction, water conservancy construction, tunnel construction, mining: rock drilling, concrete compaction,

3) Railway construction; ballast tamped.

4) In agriculture and animal husbandry: pesticide spraying, shearing.

5) Tea picking and forestry: logging, timber, and branching.

6) Wood processing: sawing, planing, tenoning, sanding.

7) Medical treatment: saw bone, drill bone, remove plaster.

8) In arts and crafts: carving, carpet cutting.

9) Special purpose: cutting steel plates, punching holes (without bending and deforming the workpiece), angle drills to drill the workpieces in small places, magnetic drills can be absorbed on the processed steel parts, self-climbing saw pipe The function automatically cuts large diameter steel pipes, the fixed torque electric wrench can control the bolts to reach a constant tension, and the riveting gun can riveting workpieces on one side.
