KINGWELL Shock Absorber Technical Data:
KINGWELL Drilling Shock Absorbers are used to greatly reduce shock and vibration in drilling applications to enhance performance and provide a much smoother drilling operation.
It can greatly reduce the damage (caused by shock) to drill bit, drilling tool, and thus increase drilling speed and save drilling cost.
We have Mechanical Shock Absorber and Hydraulic Shock Absorber.
