Pneumatic screwdrivers are used for the assembly of some precision screws, such as car parts, aviation equipment, electronic components, and other small and delicate parts that need to be assembled with screws. Moreover, the working torque range is smaller, and the screws are required to be more precise, taking the car body assembly scenario as an example, loosening screws that are not precise enough will lead to unstable car body structure, which will affect the final product and safety. If you are still looking for a precision screwdriver, the Rongpeng RP7229 air screwdriver can be tried.

Precise torque
The working torque of Rongpeng RP7229 torque screwdriver is 0.75-4N.M, and is equipped with five levels of torque adjustment function, the operator can adjust the torque according to the torque requirements of different application scenarios, and the torque adjustment accuracy can reach ±3%, which means that the error range of its torque output is controlled within 3%, this high-precision torque adjustment function enables it to provide stable tightening effect in various application scenarios and ensure assembly quality. Compared with ordinary screwdrivers, rongpeng RP7229 makes the screwdriver automatically stop working when it reaches the highest torque, which effectively prevents overwork, making the screws too tight and damaging the surface of the object.

Low noise
The assembly of precision screws requires high attention and concentration, because a slight error, too large or too small torque will affect the final result of assembly, workshop workers, operators have to face countless screw assembly in a day, suddenly feel tired, work efficiency will be reduced, and higher noise will produce excessive irritability. The noise level of rongpeng RP7229 is 90db, and the characteristics of low noise provide a quiet working environment and improve work efficiency.

Easy to operate
The Rongpeng RP7229 has a chuck size of 1/4 inch and is equipped with an automatic lock function, so the operator only needs to select the corresponding shape of the drill according to the screw assembly and disassembly of the corresponding scene，simply press down on the claping head and place it into the bit to lock it，making it convenient and fast.
