1.

The slender shape reduces unnecessary cross-section changes. Which is more conducive to the spread of the piston impact stress waves, which reduces the peak stress wave, shock wave propagation time increases, the energy transfer efficiency.

2.

In the percussion piston in the impact head design, designed to be equal or close to the area of the handle adapter, and obtain stable small amplitude shock waves, more conducive to smooth transfer.

3.

The piston face designed as an impact surface in contact with the centerline of the shank adapter, to ensure close contact with the impact surface with minimal offset and center, help to improve the energy efficiency in the transport of the piston in the threaded rod and the drill bit avoiding additional stress.
