Strives for perfection, Qi De Li impactor quality is even higher.

It has been more than a year since the QDL (HD) series impactors were put on the market. During this period, the impactors have not appeared any quality problems, and their service life and performance (such as speed, slag removal capacity) have been praised by the outside world. Compared with other brands, Qi Deli impactor has higher performance price ratio. Even so, we are constantly improving our products and pursuing new heights. Recently, Qi Deli drill has invested a lot of money to improve the manufacturing accuracy of the impactor.

Previous manufacturing processes have enabled our impactors to have high-quality performance, and domestic first-class service life. On this basis, we further reduce the dimension tolerance of the impactor and improve the surface quality of the cylinder through the new process. Compared with the previous products, our research and development has achieved the following results:

Longer service life：The surface quality is improved, the friction between the piston and the inner cylinder is reduced, and the scratch between the surface of the piston and the inner cylinder is not easy to occur, thus improving the service life of the impactor.

Lower energy consumption：The reduction of roughness reduces the fit clearance of the workpiece, and the gas has better airtightness in the air chamber. Thus, the compressed energy of the air is efficiently utilized and the energy loss is reduced.

Higher efficiency： the improvement of air-tightness, impactor piston in the movement of the loss of energy is reduced, the surface quality of the improvement makes it suffer less friction, so that the impactor piston more powerful, fast.
