In DTH hammers, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH hammers a nearly constant penetration rate regardless of hole length.
• Small to medium size drilling diameters
• Works in low pressure range, capable of drilling shallow to medium hole lengths
