Product Description

CQS-3.5 Mining Handheld Percussion Drill

1. Product overview
QS-3.5 mining hand-held percussion drill is widely used in rock, brick wall, concrete and other components. It can be used to drill holes for installing pipelines, and it can also be used for erecting power lines and installing anchor bolts. Chemical construction, road construction, dangerous and humid tunnels, sewers and narrow space operations. Especially in underground mines with gas, it can better reflect the excellent performance of explosion-proof.
The CQS-3.5 pneumatic percussion drill adopts the five-hole drill bit which is one of the common specifications in the market, which is convenient for users to purchase from hardware stores in various places, which greatly facilitates the use of users and reduces the cost.

2. Scope of application
Mainly used for drilling holes in rocks, brick walls, concrete and other components, for installing pipelines, erecting power lines, installing anchor bolts, chemical plants, refineries, construction, heavy industry, dangerous and humid tunnels, underwater and narrow space operations ; Especially in high gas explosion-proof mines, pneumatic explosion-proof no sparks can better reflect safety. It is a tool to improve work efficiency and reduce labor intensity.

3. Product features
Pneumatic percussion drill is a light and dexterous small pneumatic tool, which has the combined functions of simple impact, simple clockwise rotation and both impact and rotation.
High power, pneumatic explosion-proof and no sparks, especially in high gas mines, it can reflect its safety.
The structure is simple and easy to operate. It can be used directly when connected to the air compressor.
It is easy to use, it can work as long as there is a compressed air pipe, and there is no need to pull wires from a long distance.
With mobility and relocation, the volume can be large or small, unlimited, easy to carry, and quick to implement
The shell of the pneumatic impact drill is made of explosion-proof aluminum alloy, with high tensile strength, friction and no sparks, which greatly facilitates underground operations.
Explosion-proof body: It has excellent heat resistance, weather resistance, chemical resistance, fuel permeability resistance, gas permeability resistance, water resistance, steam resistance, ozone resistance, and shock resistance. It is made of ZL102 aluminum alloy. Friction spark explosion-proof test
Gun-type air drill: a more comfortable handheld operation mode, strong power output, easy drilling
One machine with multiple functions: can display multiple operation modes in complex environments
Comfortable hand feeling: Use non-slip matte rubber sleeve to make the palm fully fit and hold the hand firmly.
Lightweight body: the whole machine is only 3.5Kg,
