1. Product introduction:
The silent electric drill is used to detect criminals in the next room. It is mainly used in anti-hijacking and anti-terrorism investigation tasks of public security and armed police. Police personnel can drill holes in the wall with a silent electric drill without being noticed by criminals, and then go deep into the snake eyes to observe the movement in the house. It is a special equipment used for various hazardous environment investigation operations. The complete system can be quickly installed and set up, and it is easy to operate. In anti-terrorism operations, it is essential to understand the internal situation of the room.
Mute electric drill
 2. Product advantages:
Silent electric drill, first-generation flexible shaft drive, second-generation and third-generation spring propulsion, fourth-generation and fifth-generation motor automatic propulsion, sixth-generation products highlight the advantages of lightness, portability, flexibility and quick operation, and its level and technology far exceed the international similar level. In terms of volume, the noise reduction process of the machine itself and the reduction of friction with the wall can achieve the mute effect. The perfect effect of no-load noise ≤ 28.5DB is realized.

3. Features:
1. The integrated design of the whole machine requires no installation. According to the design principle of human mechanics, it has the dual functions of propulsion and impact. The design concept of hand-held propulsion allows one handle to advance forward, while the other handle continues to exert force, making it easy to punch holes.
2. The whole machine is composed of three parts: power supply, main machine and drill bit. It is simple and portable. It is also equipped with a belt. According to the characteristics of the force, the battery is hung on the waist, which greatly reduces the weight of the main machine.
3. Forward and reverse, adjustable.
4. Power supply: external power supply, which can be slung around the waist, each power supply can work for more than 6 hours.
5. With LED search light, it can work in dark conditions.
6. Drillable types: reinforced concrete walls and brick walls, metal plate walls, glass curtain walls, ceramic curtain walls, wood products, etc.
