Hammer Products
With the MIROC DTH hammers, we offer most complete down-the-hole drilling solutions. The offering covers hammer sizes from 3 to 12 inches, and drill bits, drill pipes and accessories with different characteristics and functions.
12 inch hammer is characterized by high performance and high penetration rates-or, in other words, high productivity.
Product Description
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
